Pearls Oy-sters: Small but consequential: Intracerebral hemorrhage caused by lenticulostriate artery aneurysm

摘要

Olivier Heck, Rene Anxionnat, Serge Bracard, Nancy, France: Cai et al.1 described a case of ruptured LSA aneurysm treated with surgery after a hemorrhage recurrence. They concluded that urgent treatment was necessary to minimize rebleeding risks.The surgical or endovascular treatment of these aneurysms is possible but risky as they are located deep in the brain and close to sensitive cerebral tissue.2 Very few cases of ruptured LSA aneurysms are reported. Their natural history and specifically the risk of hemorrhage recurrence are unclear.3 Several cases of spontaneous involution free of hemorrhage recurrence have been reported.In our institution, we encountered 3 recent cases of ruptured LSA aneurysms revealed by deep cerebral hematomas and we treated them conservatively. There was no hemorrhage recurrence and follow-up angiography demonstrated spontaneous thrombosis in 2 of the 3 cases.
