[Cerebrovascular disease and neurocysticercosis]. / Doença cerebrovascular e neurocisticercose.

We report three cases of stroke secondary to neurocysticercosis. The first one is a 36 years old man with bilateral middle cerebral artery occlusions who had presented acute right hemiparesia and aphasia. MRI demonstrated several enhancing subarachnoid cysts surrounding the occluded vessels, a right parietal racemose cyst and a left temporal large infarction area. Angiographic study showed total occlusion of left middle cerebral artery and a subtotal occlusion of right middle cerebral artery. The second one is a 42 years old man with vasculitis of small cortical vessels who presented with headache, seizures and focal neurological deficit. CT scan demonstrated several calcifications and a left temporal infarction area. Cerebral angiographic study was normal. The third case was a woman, 53 years old, with a past history of six stroke events and an actual behavior disturbance and seizures. MRI demonstrated several cortical and subcortical infarction areas and cisternal cysts. Angiographic study showed diffuse arteritis of basilar and carotid arterial system. In all three cases CSF study showed linfomonocitic pleocytosis and positive ELISA for cysticercosis.
