title: Inflammatory aneurysm due to neurocysticercosis.
abstract: A 69-year old man presented with a subarachnoid hemorrhage associated with a large intracerebral hematoma in the right temporal lobe. The oblique views of cranio-orbital computerized tomographic angiography (CTA) were suspicious for an aneurysm on a middle cerebral artery branch. At surgery, a cystic mass was found in the Sylvian fissure, associated with an aneurysm on a distal branch of the anterior temporal artery. The aneurysm was not situated at a bifurcation of the artery and was located beneath the cyst. It was secured by trapping. Pathological examination revealed that the cystic lesion was neurocysticercosis and that the aneurysm was inflammatory. We report a ruptured inflammatory aneurysm of a distal branch of the anterior temporal artery associated with neurocysticercosis, and present the histological findings. We believe this is the first report of such an inflammatory aneurysm with histological confirmation.
