Abstract
Cerebral aneurysms are most often located on the proximal segments of the arteries of the circle of Willis, with some predisposition towards the anterior communicating artery. However, aneurysms can develop on any cerebral arteries including abnormal ones. In this clinical observation, a case of rupture of an aneurysm located in the distal segment of the hypertrophied medial frontobasal artery is presented. The case was complicated by the presence of an aneurysm on the middle cerebral artery, the rupture of which, according to the conclusion from the primary vascular center, caused subarachnoid hemorrhage, while an aneurysm of the frontobasal artery was not detected. It was only after the patient was transferred to a regional vascular center and a targeted review of angiograms during the preparation of the patient for surgery that a distal aneurysm of the frontobasal artery was detected, which, according to the intraoperative picture, was the cause of the hemorrhage.
