Dilated venous channels traversing the sella and connecting the two cavernous sinuses were seen on contrast-enhanced MR images in four patients with angiographically proved carotid fistulas. The anatomy and variations of these so-called intercavernous sinuses are discussed and are demonstrated in Latex-injected anatomic specimens. Direct visualization of the intercavernous sinuses on contrast-e...

A 64-year-old nulliparous woman presented with clinical signs of thyroid and adrenocortical insufficiency. Subsequent hormonal investigations demonstrated a failure of all anterior pituitary functions. Pneumotomo-encephalography revealed a large arachnoid herniation, leading to the diagnosis of primary empty sella turcica syndrome with secondary panhypopituitarism. This unusual observation emph...

Two sisters who died at the age of 2.5 years and 5 weeks are described. Both showed signs of panhypopituitarism. At necropsy, no hypophysis could be found in the first child and a rudimentary and partly ectopic hypophysis was found in the other. Both children had a flat, poorly developed sella turcica, and the sellar anomaly could be seen in skull x-rays. These patients represent a hereditary s...

The paper presents anatomical considerations on the abnormal ossification, which occurred around the dorsum of the sella turcica in the human skull of the female individual. Probably the morphological alterations of the sellar region were associated with extensive heterotopic ossification of the dura mater attached to the dorsum of the sella turcica and the posterior clinoid processes. The anal...

Trans-nasal sphenoid sinus foreign body is a rare condition. We report a case of trans-nasal gun bullet within the sphenoid sinus with breach of the floor of the sella turcica. A 42-year-old soldier presented a few weeks after a gun battle with a history of headache. The skull x-ray demonstrated a foreign body in the region of sphenoid sinus and sella. Multidetector-row CT with multiplanar refo...

The detailed surgical procedure of the transsphenoidal surgery for pituitary abscess has scarcely been described previously because it is a very rare clinical entity. The authors reported two cases of primary pituitary abscess. In case 1, the anterior wall of the sella turcica was reconstructed with the vomer bone after irrigating the abscess cavity, but the sella was not packed by fat for fear...

There is a surge in fungal infections of the central nervous system due to an increase in the incidence of immunocompromised state and widespread use of antimicrobials. Despite myriad clinical presentations and skull base syndromes associated with Aspergillus infections, aspergilloma in the sella is relatively rare. We report a rare case of aspergilloma of the sella and parasellar region in a p...

The empty sella syndrome (ESS) presents a varied clinical and radiographic picture. It may remain asymptomatic or may stimulate an intrasellar growth thereby causing diagnostic and therapeutic problems. An air encephalogram (AEG) is required for diagnosis. The purpose of this paper is to review the clinical and radiological features of the ESS and to discuss the pathogenetic mechanisms involved.

PURPOSE To document the accuracy of CT and MR of the sella turcica for detecting adrenocorticotropic hormone-secreting adenomas in Cushing disease. METHODS The radiologic findings of the sella turcica prior to transsphenoidal surgery are reviewed in 141 patients who had biochemical evidence of pituitary-dependent Cushing disease. Axial thin-collimation CT scans with sagittal and coronal refor...

The aim of this study was to assess and compare the dimensions of Sella Turcica in 90 subjects grouped as Group A (Skeletal Class I: ANB 0-4°, Wits value -1to 0.5 mm)1.4 and Group B (Skeletal Class II: ANB>4°, Wits value >0.5 mm) aged 14-30 years each having 45 subjects. For Group A Width (W) of Sella Turcica10 is found to be 15.33 mm + 2.77 S.D, Depth (D) 6.43 mm + 1.45 S.D, Area (A) 66.05 mm2...
