In adults, the gland is slightly larger in females compared to males. The anterior lobe, adenohypophysis, forms about 75–80% of the gland and is a center for hormone synthesis, including thyroid stimulating hormone (TSH), adrenocorticotrophic hormone (ACTH) and prolactin. The sella turcica is a bony depression in the sphenoid bone. The sella turcica is a bony depression in the sphenoid bone. 11, No. Completing the formation of the saddle posteriorly is the dorsum sellae which is continuous with the clivus, … The sella is covered by a dural reflection (i.e., diaphragma sellae) above which lies the suprasellar cistern. Sella Turcica is a bony cavity housing the pituitary gland, which is located in the brain and responsible for secreting a number of hormones. The above photos are from young rats ranging from 2.5 – 8 weeks of age. It lies in a small depression called the sella turcica which is Latin for “Turkish saddle”. Treatment entails supporting the patient and addressing any associated endocrine dysfunction present. However, some may develop a constellation of symptoms including hypopituitarism, inferior displacement of the optic tracts with associated visual disturbance, rhinorrhea, and other symptoms pertaining to elevated intracranial pressure (ICP). As the roentgen image of the sella is dependent on the configuration of the sphenoid bone, dorsum sellæ, and clinoid processes, observation was limited to the variations found in these structures. These techniques are limited because they do not necessarily reflect true pituitary size. ScienceDirect ® is a registered trademark of Elsevier B.V.

The various averages for these dimensions are given in Figure 1, under their respective headings. Reliability of … While the shape and size of the sella turcica can vary slightly, depending on the person and the age, it is usually very easy to … Although variations exist, the sella turcica generally should not exceed an anteroposterior dimension of 16 mm or a vertical depth of 12 mm on a lateral skull radiograph. Anatomy [edit | edit source]. Do cervical spine X-rays for trauma have clinically significant incidental findings? 110, No. He found the average length measurement of the fossa to be 1.16 cm. The sella is bordered laterally by the cavernous sinuses, superiorly by the diaphragma sella (dural fold), anteroinferiorly by the sphenoid sinus and posteriorly by the pontine cistern. Adjacent to the posteroinferior aspect of the cavernous sinus lies Meckel’s cave, which harbors the gasserian ganglion. 19.5 and 19.6), medical therapy for macroadenomas, spontaneous pituitary apoplexy, trauma, infection, autoimmune disease, and Sheehan syndrome.4, Olga Moshkin, ... Kalman Kovacs, in The Pituitary (Third Edition), 2011. If you have empty sella syndrome, your sella turcica is … At this stage of development the pituitary gland is small and pale pink in color. 42, No. Also, the floor of the sella turcica is normally well defined by a single cortical line. The two can be differentiated on imaging because the posterior lobe characteristically demonstrates increased T1 signal on unenhanced images, while the anterior lobe is isointense to gray matter on T1-weighted images. Fitzgerald also concluded that there was an inverse ratio between the length of the fossa and the anterior measurement of the base. The sella turcica is a structure in the skull which is designed to support the pituitary gland.This important gland at the base of the brain releases a number of different hormones from its snugly positioned spot in the sella turcica. Journal of Cranio-Maxillofacial Surgery, Vol. The volume is the product of one-half length × width × height. The sella turcica is a spherical depression in the superior surface of the sphenoid bone. and the average anterior and posterior depth measurements to be 0.70 and 0.78 cm., respectively. Ray N.

It is usually larger in females than in males - in females the superior border tends to be convex, whereas in males it is usually concave. Radiology department of the University of Toronto, Canada and the Radiology department the Medical Centre Alkmaar, the Netherlands. 4, 13 September 2009 | The European Journal of Orthodontics, Vol. The prevalence of pituitary metastasis in autopsy series of cancer patients ranges up to 26.7% with most reports quoting around 3–5%. Ramsey Ashour, ... Harry van Loveren, in Chordomas and Chondrosarcomas of the Skull Base and Spine (Second Edition), 2018. Sella Turcica and Parasellar Region. It is divided into three fragments and consists of an anterior wall, a floor, and a posterior wall. The greatest transverse measurement, or width, represents the distance between the lateral boundaries of the fossa. Jeffrey A. Hashim, Juan E. Small, in Neuroradiology, 2019, The empty sella turcica was first described in 1949 as a condition where the sella turcica is only partially filled by the pituitary gland, which appears flattened against the sellar floor (Fig. The anteroposterior diameter of the sella has been defined as a line connecting the tuberculum with the farthest portion of the posterior sella wall. A Comparison of two Radiological Methods of Measurement, Radiographic Determination of the Growth of the Pituitary Fossa in Pre-school Children, Further roentgenographic studies of the sellaturcica in abnormal children, On the dimensions of the hypophyseal fossa in man. \ Medical Definition of sella turcica : a depression in the middle line of the upper surface of the sphenoid bone in which the pituitary gland is lodged Learn More about sella turcica The pituitary gland normally sits within the sella. The two can be differentiated on imaging because the posterior lobe characteristically demonstrates increased T1 signal on unenhanced images while the anterior lobe is isointense to gray matter on T1-weighted images. Sella turcica – a saddle-shaped depression. Subcranial Relationships The pituitary gland and sella are located in the cranial base below the center of the brain (Fig. Sharon E. Oberfield MD, ... Daniel Esten Hale MD, in Pediatric Secrets (Fifth Edition), 2011. Shown Sella turcica, anterior and posterior clinoid processes, dorsum sallae, and clivus are shown. Lateral to the sella turcica are the cavernous sinuses containing the carotid arteries and cranial nerves III, IV, V1 (ophthalmic division of trigeminal nerve), and VI. The anterior lobe, adenohypophysis, forms about 75–80% of the gland and is a center for hormone synthesis, including thyroid-stimulating hormone, adrenocorticotropic hormone (ACTH), and prolactin. The most common symptom reported by people with primary em… There are two general types of pituitary tumours—hormone secreting and nonsecreting. Eric C. Bourekas, ... H. Wayne Slone, in Handbook of Neuro-Oncology Neuroimaging (Second Edition), 2016. This chapter focuses on the anatomic basis of the microsurgical and endoscopic approaches to the sellar and parasellar regions. Dennis M. Marchiori, in Clinical Imaging (Third Edition), 2014. Hypophyseal fossa – the deepest part of the sella turcica, where the pituitary gland is located. However, in the first 6 weeks of life the anterior pituitary is bright as well on T1-weighted images in 82%.3 The size and configuration of the pituitary gland are thought to vary by age and sex. The height of a normal gland can be up to 9 mm.4 The gland tends to enlarge during puberty and pregnancy. Copyright © 2021 Elsevier B.V. or its licensors or contributors. 317, American Journal of Physical Anthropology, Vol. The pituitary gland normally sits within the sella. The sella turcica is a protruding bone of the sphenoid bone (sphenoid bone) at the inner base of the skull. In an autopsy study of 739 cancer patients, one-half of the pituitary metastases constituted the only metastatic deposit in the CNS. 2 Trends in the radiological study of pituitary adenoma Therefore, caution must be exercised in suggesting pituitary gland pathology in young adolescent patients and women of child-bearing age. The sellar floor may become sclerotic in some cases of craniopharyngioma and nasopharyngeal carcinoma [1]. The vertical or depth measurement was taken along a line dropped from the antero-posterior line to the deepest point on the floor of the sella. - Anterior and posterior clinoids are superimposed. Intrasellar, parasellar, or suprasellar fat and calcifications may be excellent indicators of pathology. The pituitary gland, which weighs about 0.5 g in the adult, is the only structure of … Investigators have also attempted to use the area and the volume of the sella turcica to serve as better predictors of pituitary disease. The suprasellar cistern contains the supraclinoid internal carotid arteries, pituitary stalk, and the optic nerves, chiasm, and tracts. Recent studies report an overall incidence on imaging of 12%.3 Most patients with an empty sella on imaging are asymptomatic. Sella Bony anatomy. Marcel Maya, Barry D. Pressman, in The Pituitary (Fourth Edition), 2017. 1, Orthodontics & Craniofacial Research, Vol. Focal erosion of the lateral margins secondary to an aneurysm, focal erosions of the floor by pituitary lesions, and selective erosion of the posteroinferior floor secondary to chronic increased intracranial pressure [3,4] are some of the more dependable findings. 2, American Journal of Medical Genetics Part A, 10 March 2008 | Journal of Oral Pathology & Medicine, Vol. Initial enthusiasm emphasized visualization of small areas of sella floor erosion and/or depression. Access to the sella… Eric C. Bourekas, ... H. Wayne Slone, in Handbook of Neuro-Oncology NeuroImaging, 2008. An empty sella can be completely asymptomatic. The length of the fossa was more influenced by variations in the posterior measurement than in the anterior measurement. Sellar width is defined as the wid… The depth measured perpendicular to the sella floor, from a line drawn between dorsum and tuberculum, should not exceed 13 mm in most cases. According to Taveras and Wood [1], 17 mm is the upper limit of normal for the maximum anteroposterior diameter of the sella. 5, 1 December 2011 | The Journal of Psychiatry & Law, Vol. The gland itself is composed of an anterior lobe, intermediate (vestigial) and posterior lobe. Anteriorly, the sella turcica is bound by the tuberculum sellae and anterolaterally by the anterior clinoid processes. Thickening of the tuberculum or of the clinoid processes, and blistering of the planum sphenoidale have frequently been reported in association with meningiomas of the sella turcica. The sella turcica is a bony depression in the sphenoid bone. The cavernous sinus is made up of very thin walled veins that make up a venous plexus. Other patients may develop an empty sella secondarily in response to pituitary surgery or radiotherapy for adenomas (Figs. The sellar floor can be studied on frontal radiographs angled tangentially to the plane of the floor (Caldwell view). Sella Turcica – Upright Lateral 6. The pituitary gland normally sits within the sella. …portion of this seat, or sella turcica (“Turk’s saddle”), is actually wall-like and is called the dorsum sellae. 21, No. SELLA TURCICA Simplified - Anatomy | Presented By Dr. Afshan Jabeen Former Jr. Resident Doctor, JPNTC, AIIMS Anatomy of the Sella Turcica The anterior, posterior, and inferior walls of the sella turcica are bony while the lateral walls and roof are made of dura that slings between the anterior and posterior clinoid processes. 6, Neurosurgery Clinics of North America, Vol. This represents the true antero-posterior dimension of the outlet of the pituitary fossa. The pituitary gland, sella turcica and the parasellar region can be involved by a wide variety of nonneoplastic tumor-like lesions as well as by numerous benign and malignant neoplasms. ANATOMY. In the sphenoid bone, the anterior boundary of the sella turcica is completed by two small eminences, one on either side, called the middle clinoid processes, while the posterior boundary is formed by a square-shaped plate of bone, the dorsum sellae, … 2, © 2021 Radiological Society of North America, Incidence and morphometry of sellar bridges and related foramina in dry skulls: Their significance in middle cranial fossa surgery, A CBCT Investigation of the Association between Sella-Turcica Bridging and Maxillary Palatal Canine Impaction, The Enigma behind Pituitary and Sella Turcica. Blood Supply. The pituitary (hypophyseal) fossa or sella turcica is a midline, dural lined structure in the sphenoid bone, which houses the pituitary gland. Diaphragma sellae • Forms roof of sella turcica • covers the pituitary gland, except in its center, which transmits the pituitary stalk • thin, tenuous structure not an adequate barrier for protecting the suprasellar structures during transsphenoidal operation • deficiency of the diaphragma sellae assumed to be a precondition to formation of empty sella. The dimensions of the sella turcica in normal, specimens were measured in the antero-posterior, vertical, and transverse directions. The sella turcica is a bony depression in the sphenoid bone. Pituitary tumour, most common cause of enlargement of the sella turcica, the bone cavity in the head in which the pituitary gland is located. An enlarged sella turcica is a significant finding, suggesting the presence of a pituitary neoplasm, empty sella syndrome, extrapituitary neoplasm, or possibly a normal variant of the patient's anatomy. The sella is bordered laterally by the cavernous sinuses, superiorly by the diaphragma sellae (dural fold), anteroinferiorly by the sphenoid sinus, and posteriorly by the pontine cistern. Empty sella is the presence of CSF within an enlarged sella turcica. From these he concluded that the length of the fossa reaches its maximum when the posterior measurement of the basis cranii is greatest, and varies directly with it. The cavernous sinus receives venous blood from the following: 5, The British Journal of Radiology, Vol. Criteria The sella turcica is visualized without rotation or tilt as indicated by the following: - Sella turcica and clivus are demonstrated in profile. 32, No. Anteroinferiorly, the foramen rotundum conducts V2 (maxillary division of trigeminal nerve). A small sella turcica may be associated with pituitary insufficiency, but the correlation is poor [1] and most small sellas are of no significance. The anterior boundary of the sella turcica is completed by two small eminences, one on either side, called the middle clinoid processes, while the posterior boundary is formed by a square-shaped plate of bone, the dorsum sellæ, ending at its superior angles in two tubercles, the posterior clinoid processes, the size and form of which vary considerably in different individuals. Eval. The pituitary gland normally sits within the sella. The sphenoid sinus is inferior and anterior to the sella turcica, the paired cavernous sinuses are lateral, the suprasellar cistern and its contents are superior, and the basilar artery and brainstem are posterior . A variety of conditions can lead to sellar enlargement, including tumors of the pituitary or functional hypertrophy of the pituitary, which may occur in primary hypothyroidism or primary hypogonadism. However, in the first six weeks of life the anterior pituitary is bright as well on T1-weighted images in 82% [3]. This has been referred to as the empty sella syndrome (Figs. The cavernous sinus is located on either side of the sella turcica and superior to the sphenoid bone. Cope, in a study of the pituitary fossa in fifty skulls, concluded that normally there is a great variation in its size, so that there is no particular age at which any special increase occurs. His study of the various shapes of the fossa showed the oblong and cuboidal types to prevail. An area greater than 130 mm2, and a volume greater than 1092 mm3, have been reported to be abnormal [2]. The antero-posterior measurements were taken from the most dorsal point of the tuberculum sellæ in the sagittal plane to the anterior edge of the dorsum sellæ in the same plane.

The real designation of the sella turcica, however, was introduced to the anatomical nomenclature by the anatomist Adrianus Spigelius (1578-1625) in … The appearance of two cortical lines is known as a “double-floor” sign, suggesting osseous erosion of the floor by an expansile mass. The posterior lobe, neurohypophysis, is connected to the hypothalamus by the pituitary stalk and receives hormones from the hypothalamus via the pituitary stalk (i.e., antidiuretic hormone). It is covered also by the brain coverings and has no connection with the exterior of the cranium… Read More 4, American Journal of Orthodontics and Dentofacial Orthopedics, Vol. He also measured the length, breadth, anterior depth and posterior depth of the fossa. Therefore, caution must be exercised in suggesting pituitary gland pathology in young adolescent patients and women of childbearing age. THE roentgenologic interpretation and significance of changes, in and about the sella turcica are so dependent on an accurate knowledge of the normal and pathologic anatomy of this structure that this study was undertaken in an effort to demonstrate in a series of 110 cases the normal and pathologic changes found postmortem. The seat of the saddle is known as the hypophyseal fossa, which holds the pituitary gland.The hypophyseal fossa is located in a depression in the body of the sphenoid bone.Located anteriorly to the hypophyseal fossa is the tuberculum sellae.. Anterolateral to the gasserian ganglion, V3 (mandibular division of trigeminal nerve) exits through the foramen ovale. There are five types of hormone-secreting pituitary tumours, named according to the cells that produce the particular hormone. Fitzgerald, in a study of one hundred skulls, endeavored to show a relationship between the size of the pituitary fossa and the skull. The Sellar spine was first described by Lang (1977). Surgery may be warranted. Numerous studies of the “normal” sella turcica size were performed and reported prior to CT and MR. Enlargement of the sella turcica was thought to be an indicator of pituitary pathology, as were distortion of shape and contour of the sella. Metastases are also the most frequent tumor of the eurohypophysis, which is affected about twice as often as the adenohypophysis. The sella is bordered laterally by the cavernous sinuses, superiorly by the diaphragma sellae (dural fold), anteroinferiorly by the sphenoid sinus, and posteriorly by the pontine cistern. The posterior lobe, neurohypophysis, is connected to the hypothalamus by the pituitary stalk and receives hormones from the hypothalamus via the pituitary stalk (i.e. The sella turcica is a midline depression in the sphenoid bone which contains the pituitary gland and distal portion of the pituitary stalk. 2 Anatomy of the Sellar and Parasellar Region Albert L. Rhoton Jr. In adults, the gland is slightly larger in females when compared to males. Aneurysms may demonstrate eggshell or other calcification patterns. 39, No. This review is based on a presentation given by Walter Kucharczyka and was adapted for the Radiology Assistant by Marieke Hazewinkel. Empty sella syndrome, in contrast, is merely a description of what is seen on an imaging study, and there is no typical set of clinical signs or symptoms associated with this imaging finding. Dorsum sellae – forms the posterior wall of the sella turcica. This chapter provides a well-illustrated review of the sellar tumors. The gland itself is composed of an anterior lobe, intermediate (vestigial) lobe, and posterior lobe. Posterior to the sella are the posterior clinoid processes, dorsum sellae, and interpeduncular cistern containing the basilar apex and cranial nerves III and IV. ; The anterior borders of the sella are formed by the anterior clinoid processes of the lesser sphenoid wing and the tuberculum sellae, while the posterior border is formed by the dorsum sellae. Anatomically, the sella turcica has been expressed as variable. Sella turcica: A depression in the base of the skull where the pituitary gland is situated. Anatomy. Meningiomas frequently calcify, and on rare occasions pituitary tumors calcify (pituitary stone). That line corresponds to the plane of the diaphragma sellae. Strictly speaking, empty sella syndrome is not a syndrome at all, since a syndrome is a set of medical signs or symptoms that tend to occur together. On a coronal section through the brain the reference structure is the pituitary gland which lies in the sella turcica. The pituitary gland is thus situated in almost the centre of the cranial cavity. Unfortunately this has not withstood the close scrutiny of subsequent carefully performed radiologic/pathologic/surgical studies [3,4]. The sella turcica from Latin (turkish chair) is a saddle-shaped depression in the dorsal surface of the basisphenoid's body; with a median depression corresponding to the pituitary gland, the hypophysial fossa (Fossa hypophysialis), limited caudally by a plate more or less prominent and lifted forward: the dorsum sellae. A wide range of normal exists, and this has been expanded with information gained from CT and MR. For instance, visualization of an “enlarged” empty sella in an asymptomatic patient indicates that sella turcica size alone is not a valid determinant of pituitary disease. He adopted two measurements, one taken from the tip of the ethmoid spine of the sphenoid to the anterior limit of the optic groove (anterior measurement of the basis cranii), the other from the opisthion to the middle of the dorsum sellæ (posterior measurement of the basis cranii). antidiuretic hormone (ADH)). 14-9).14 The depth of the sella is measured as the greatest distance perpendicular to a line connecting the tip of the dorsum sellae to the tuberculum sellae. Thin-section (1–2 mm), high-resolution, multidirectional tomography was initially expected to improve the sensitivity for diagnosis of pituitary lesions, particularly microadenomas. Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username. The size and configuration of the pituitary gland is thought to vary by age and sex. It was called the sella turcica (the Turkish saddle) because of its resemblance to a saddle used by the Turks which had supports in the front and back. The name reflects the anatomic shape of the saddle-like prominence on the upper surface of the sphenoid bone in the middle cranial fossa, above which sits the pituitary gland. The dural roof of the … 39, No. 27, No. The gland tends to enlarge during puberty and pregnancy. The name goes back to the Belgian anatomist and professor of anatomy and surgery Adriaan van den Spieghel (1578 - 1625). Its most important value is its relative stability, practicality and the ease of location of both points Sella and Nasion. The sella and surrounding processes were removed in toto and the soft tissues dissected from the bone. The sella turcica ("Turkish saddle") is a concave, midline depression in the basisphenoid that contains the pituitary gland (also called the hypophysis). The sella turcica is an indentation in the sphenoid bone at the base of your skull that holds the pituitary gland. These figures do not vary greatly from those obtained by other observers, and various discrepancies are probably due to the different methods of measurement elected. Abstract THE roentgenologic interpretation and significance of changes, in and about the sella turcica are so dependent on an accurate knowledge of the normal and pathologic anatomy of this structure that this study was undertaken in an effort to demonstrate in a series of 110 cases the normal and pathologic changes found postmortem. The average length of the sella is 10.5 mm and a range of 5 - 16 mm and an average width of 14.0 mm and a range of 10 - 16 mm.
