OBJECTIVE AND IMPORTANCE: Two cases of inflammatory aneurysms in patients with neurocysticercosis have been reported previously. Clinical and radiographic studies suggest a causal relationship. CLINICAL PRESENTATION: A man with neurocysticercosis presented with an acute subarachnoid hemorrhage from a left middle cerebral artery aneurysm. INTERVENTION: The patient underwent a craniotomy and clipping of his aneurysm. Diffuse inflammatory changes and multiple cysticercal cysts were found throughout the left sylvian fissure. CONCLUSION: 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.
