Abstract
A previously healthy, HIV-negative, 40-year-old man presented with a 2-month history of progressive weakness of his left arm. Magnetic resonance imaging revealed an intradural, extra medullary plaque-shaped lesion at C6-T1 levels with high contrast enhancement. Based on the patient's clinical and radiologic findings, it was believed that the patient had an en plaque meningioma, and he was operated on. Histologic examination of the mass revealed granulomas with multinucleated and Langhans-type giant cells, typical of a tuberculoma. Intradural extramedullary tuberculomas should be considered in the differential diagnosis of en plaque meningioma as a rare entity.
