Eosinophilic granuloma mimicking a pituitary tumor.

The authors present the case report of a patient in whom hypopituitarism, diplopia, and visual field defects were due to eosinophilic granuloma. Radiographic studies were suggestive of a pituitary tumor and subsequent histological evaluation showed replacement of the anterior pituitary by histiocytic cells. Eosinophilic granuloma should be included in the differential diagnosis of an intrasellar mass.

Embolization of a traumatic arteriovenous fistula of the scalp with radiopaque Gelfoam pledgets. Case report and technical note.

A large traumatic arteriovenous malformation of the scalp was embolized with Pantopaque-saturated Gelfoam pledgets, which made fluoroscopic monitoring of the radiopaque emboli possible. Postembolization angiography demonstrated complete occlusion of the malformation. There is still no clinical or physical evidence of recurrence after an 8-month follow-up period.
