Distal anterior choroidal artery (AChA) aneurysms are infrequent. We discuss the case of a 59-year-old patient who presented with an isolated intraventricular hemorrhage (IVH) secondary to a ruptured distal AChA aneurysm. Initial noninvasive cerebral computed tomography angiography revealed no evidence of an underlying vascular pathology. The patient underwent further digital subtraction cerebral angiography, which revealed an aneurysm arising from the distal AChA segment. The aneurysm was successfully treated with surgical clip ligation. The current study highlights the importance of considering a ruptured distal AChA aneurysm as a potential source of isolated IVH.

Key-words:

Distal anterior choroidal artery aneurysm - intraventricular aneurysm - intraventricular hemorrhage
