Subarachnoid hemorrhage as a result of fungal aneurysm at the posterior communicating artery associated with occlusion of the internal carotid artery: case report.
BACKGROUND
Fungal or "true" mycotic aneurysms of the intracranial circulation are very rare. Rupture of a fungal aneurysm is fatal in almost 100% of cases.


METHODS
We report a 65-year-old woman with a ruptured fungal aneurysm on the posterior communicating artery associated with occlusion of the internal carotid artery. She had a past history of gastric malignant lymphoma and subsequent granulocytopenia. She survived after surgical treatment including trapping of the aneurysm and a superficial temporal artery-to-middle cerebral artery bypass.


CONCLUSIONS
Improved immune response at the time of the onset of subarachnoid hemorrhage, as well as additional vasoreconstructive surgery, may have contributed to favorable outcome after surgical treatment.
