Neurocysticercosis Presenting as Midbrain Syndrome

Abstract

Brainstem is infrequently involved in patients with neurocysticercosis, usually, it occurs in association with disseminated form of neurocysticercosis. We are reporting two cases who had large multiple cysticercus lesions and presented as acute midbrain syndrome. The diagnosis of neurocysticercosis was established by presence of characteristic granulomatous extraaxial lesions around the midbrain, and in cerebral parenchyma, along with strongly positive ELISA for cysticercal antigen in cerebrospinal fluid as well as in serum. Both patients responded well to corticosteroids. However, repeat follow-up CT scan in one case did not show significant alteration in the size of the lesion.
