Caudate haemorrhage caused by pseudoaneurysm of accessory middle cerebral artery

Year: 2015

Type: article

Abstract: A 68-year-old man experienced a right caudate haemorrhage with intraventricular haemorrhage. Although a subarachnoid haemorrhage was not shown clearly, our investigation demonstrated an aneurysm-like vascular pouch located in the anomalous vessel arising from the A2 segment of the right anterior cerebral artery. Rupture of the vascular pouch was considered to be the cause of the caudate haemorrhage. Neck clipping was performed. In intraoperative observation, the anomalous vessel was diagnosed as a right accessory middle cerebral artery. Histopathology of the saccular wall showed only an adventitia and a fibrin layer, indicating a pseudoaneurysm. We routinely perform detailed vascular evaluation for any cerebrovascular disease. A meticulous vascular survey makes it possible to obtain valuable clues in cases such as caudate haemorrhage due to pseudoaneurysm of the accessory middle cerebral artery, leading to prevention of rebleeding.
