Abstract
Ten patients with pseudotumor cerebri were studied. The diagnosis was based on bilateral papilledema and absence of intracranial masses and hydrocephalus. Based on the radiological findings, 3 groups of patients emerged: (A) Five patients with an empty sella; 4 had an enlarged sella; (B) Two patients with a pituitary adenoma; and (C) Three patients without sellar or pituitary pathology. The onset of symptoms was acute in 4 patients, 2 from group A and 1 each from groups B and C. One patient from group A had a lesion of the chiasma. Two patients from group B and 2 from group C had symptoms and signs suggesting engagement of structures in the cavernous sinus. Pseudotumor cerebri may be caused by bilateral compression of the cavernous sinuses because of acute necrotic swelling of a preexisting pituitary adenoma.Keywords
