Mycotic (Aspergillus) arteritis resulting in fatal subarachnoid hemorrhage: a case report.

A seventy-one year-old Japanese man suffering from carcinoma of the common bile duct died from subarachnoid hemorrhage secondary in intracranial mycotic arteritis (MA). Repeated cultures of the discharge from the draining tubes, the tip of intravenous hyperalimentation catheters, blood, sputum, and urine failed to grow any fungus. Autopsy disclosed MA due to Aspergillus at the terminal portion of the right internal carotid artery close to the posterior communicating artery.
