Ruptured intracranial aneurysms arise on or near the circle of Willis. Peripheral aneurysms are much less common and are often related to trauma or infection. We present the case of a 7-month-old male infant with subarachnoid hemorrhage. Angiography disclosed a large aneurysm arising distally from the left middle cerebral artery. The infant was operated on successfully and his condition is normal.
