Inflammatory aneurysm and neurocysticercosis: further evidence for a causal relationship? Case report.

Abstract

Two cases of inflammatory aneurysms in patients with neurocysticercosis have been reported previously. Clinical and radiographic studies suggest a causal relationship. A man with neurocysticercosis presented with an acute subarachnoid hemorrhage from a left middle cerebral artery aneurysm. The patient underwent a craniotomy and clipping of his aneurysm. Diffuse inflammatory changes and multiple cysticercal cysts were found throughout the left sylvian fissure. The patient had an uneventful recovery. Angiography suggested an inflammatory rather than a congenital aneurysm. Although rare, neurocysticercosis may induce aneurysm formation in the appropriate setting.
