Primary Intrasellar Coccidioidomycosis Simulating a Pituitary Adenoma

Abstract

Abstract The case of a 68-year-old woman who had relatively acute, unilateral ophthalmoplegia is reported. Radiological studies indicated a mass lesion involving the pituitary gland and left cavernous sinus. Pathological tissue obtained by the transsphenoidal approach revealed the presence of a Coccidioides granuloma. This pathological entity should be considered when evaluating patients with a pituitary mass and ophthalmoplegia.
