PURPOSE This study was performed to assess the reproducibility of identifying the sella turcica landmark in a three-dimensional (3D) model by using a new sella-specific landmark reference system. MATERIALS AND METHODS Thirty-two cone-beam computed tomographic scans (3D Accuitomo® 170, J. Morita, Kyoto, Japan) were retrospectively collected. The 3D data were exported into the Digital Imaging a...

BACKGROUND Dopamine agonists are widely used in the treatment of pituitary prolactinomas. We report a case of inferior mesial frontal lobe (gyrus rectus) and chiasmal herniations into an enlarged sella following successful medical treatment of a pituitary macroadenoma. METHOD A 71-year-old healthy man presented to medical attention with visual complaints. On examination, he was found to have ...

The empty sella Syndrome, is a condition resulting from herniation of the subarachnoid space through diaphragma sella, displacing normal pituitary gland. Empty can be two types: partial or complete. Partial means, cerebrospinal fluid fills less than 50% sella. Total means more with thickness gland being < 2 mm. This case 40-year-old female, recurrent attacks sudden and excruciating pain in head...

INTRODUCTION Ectopic pituitary adenoma is defined as adenoma that occurs outside the sella without any continuity with the normal pituitary gland [1]. Since its description for the first time in 1909 by Erdheim in the vomero-sphenoidal region, about 75 cases have been reported in literature [2-12]. Sphenoid sinus followed by the suprasellar region remains the most common site for these adenomas...

The purpose of this study is to determine the anatomical features of the sphenoid sinus using computerized tomography (CT). 100 Sudanese subjects were investigated for CT sinuses; Characterization of the sphenoid sinus and seven horizontal and vertical measurements were evaluated. Onodi cell was found in 13 subjects, 10 of them were sellar and 3 were pre-sellar. Pneumatization was of the sellar...

The purpose was to compare the sella turcica morphology of individuals within pairs of monozygotic twins with normal karyotype and to analyze the similarity between the observed morphology and the morphology of non-twins at the same age with normal karyotype. Profile radiographs from 84 individuals of 42 twin pairs (18 male and 24 female pairs, aged 18-23 years) comprised the material. Sella tu...

Autoimmune hypophysitis (AH) is an inflammatory disease that can present either as empty sella or as pituitary mass. A 16-years-old girl was admitted at our Unit for primary amenorrhea. A pituitary MRI performed 2 years before for severe headache demonstrated a large sellar and suprasellar lesion. As a craniopharyngioma was suspected, the consultant neurosurgeon suggested the removal of the les...

Age determination of unknown dead bodies in forensic personal identification is a complicated process which involves the application of numerous methods and techniques. Skeletal remains are less exposed to influences of environmental factors. In order to enhance the accuracy of forensic age estimation additional properties of bones correlating with age are required to be revealed. Material and ...

Sheehan syndrome is the clinical manifestation that results due to necrosis of pituitary gland resulting from severe postpartum haemorrhage during pregnancy and one causes empty sella, complete absence gland. Partial sella term given when part visible on imaging. The hormonal deficiencies syndromes are thus respectively named as complete/empty partial syndrome. Incidence especially extremely ra...
