Аннотация
OBJECTIVE: Aneurysms originating from perforating branches of the middle cerebral artery are quite rare. Most of them arise from the lenticulostriate arteries, frequently located within the basal ganglia. We report a perforating artery aneurysm that was entirely embedded within the limen insulae.
CLINICAL PRESENTATION: A 41-year-old man presented with an insular hematoma without subarachnoid hemorrhage caused by rupture of a small aneurysm on a perforating artery of the proximal middle cerebral artery supplying the insula.
INTERVENTION: This rare aneurysm was resected via the transsylvian-insular approach.
CONCLUSION: Although very rare, perforating artery aneurysms should be considered in young or middle-aged patients with an atypical intracerebral hematoma. This report discusses radiological and surgical characteristics of this unusual aneurysm.
