Abstract:
PURPOSE: In this study we evaluated the hypothesis that sella turcica enlarged in size due to increased intracranial hypertension by measuring the sella turcica area using magnetic resonance imaging (MRI) in patients with increased intracranial hypertension and compared to normal controls. METHODS: Brain magnetic resonance (MR) midsagittal images of patients diagnosed with pseudotumor cerebri from 2005 to 2012 at Dankook University Hospital and 10 normal controls who had no overt signs or symptoms of neurological disease and had normal gadolinium-enhanced MR examination of brain were compared. The area of the sella turcica was measured by the double-blind method using Dicomworks v 1.3.5b (Philippe Puech and Loic Boussel, Freeware, France). Statistical analysis was conducted using GraphPad Prism (GraphPad Software, Inc., USA) and Mann-Whitney U-test. RESULTS: The sella turcica areas of 2 pseudotumor cerebri patients were 93 mm2 and 123 mm2 and were significantly larger than in the controls (p = 0.03). CONCLUSIONS: Empty sella which commonly occurs in pseudotumor cerebri can be caused by pituitary gland atrophy but, conversely, can result from the enlargement of the bony sella in response to an abnormal cerebrospinal fluid pressure gradient.
