Distal anterior choroidal artery aneurysm: intraoperative localization and treatment.
Distal anterior choroidal artery aneurysms with intraventricular hemorrhage are rare and difficult to treat. We report the case of a 46-year-old woman with a left distal anterior choroidal artery aneurysm presenting as a typical subarachnoid hemorrhage from which she had no focal neurological signs. Because the aneurysm was located within the dominant deep temporal lobe, we used intraoperative computed tomography to guide a probe to the aneurysm to allow minimal dissection. This is the first report of a successfully treated distal anterior choroidal artery aneurysm. Reports of this unusual aneurysm and methods of approaching deep temporal lesions are reviewed.
