title: Intracranial mycotic aneurysm caused by Aspergillus--case report.
abstract: A 75-year-old female with chronic renal failure diagnosed as Wegener's granulomatosis was receiving steroids and immunosuppressive agents when subarachnoid hemorrhage developed. Cerebral angiography showed a fusiform aneurysm arising from an angular branch of the left middle cerebral artery. Hemorrhage occurred and the aneurysm was excised by emergency surgery. Microscopic examination of the aneurysm revealed dense infiltration of hyphae identified as Aspergillus. She died of subsequent hemorrhage. Autopsy showed numerous Aspergillus hyphae in the lung. Fungal mycotic aneurysm should be considered in the differential diagnosis of an immunocompromised patient with subarachnoid hemorrhage.
