Intraventricular neurocysticercosis mimicking colloid cyst

Abstract

The authors recently encountered a unique case of anterior third ventricular neurocysticercosis in which the cyst exhibited an unusually high signal on T1-weighted magnetic resonance imaging. The lesion's signal intensity and location made differentiation from colloid cyst difficult. Intraventricular neurocysticercosis should be included in the differential diagnosis of a colloid cyst.
