CYSTICERCOSIS PRESENTING AS A MASS LESION AT FORAMEN OF MONRO

Cysticercosis is a parasitic infestation that commonly affects the central nervous system. This is a report of computed tomography findings in a patient with a noncaleified cyst causing asymmetric lateral ventricular obstruction at the foramen of Monro. The lesion was isodense and uniformly enhancing, an unusual finding possibly related to presentation early in the course of the disease. This disease should he considered in the differential diagnosis of the lesions at the foramen of Monro in patients with appropriate residence or travel history. © 1979 Raven Press, New York.
