Surgical Management and Role of Medical Therapy in Ruptured Aneurysmal Neurocysticercosis

Abstract

We describe the case of an 80-year-old Hispanic male with an acute subarachnoid hemorrhage (SAH) due to an inflammatory middle cerebral artery (MCA) aneurysm rupture. Two years prior to this episode, the patient had undergone a resection of a left intracranial neurocysticercosis lesion. A current CT, CTA and MRI showed significant SAH, a left MCA aneurysm and a cystic lesion compatible with neurocysticercosis. Intraoperatively, this aneurysm was found to be adjacent to a neurocysticercosis cyst, a diagnosis confirmed by surgical pathology. Only a few cases of subarachnoid hemorrhage due to an inflammatory brain aneurysm have been reported. Due to the associated higher incidence of intraoperative rupture and difficulty clipping, our paper highlights the importance of considering an inflammatory origin in patients with a history of neurocysticercosis and subarachnoid hemorrhage. This is the oldest patient on record reported for this diagnosis and surgery.
