Basilar aneurysm and coarctation of the aorta

Abstract

A 31-year-old male presented with subarachnoid haemorrhage due to a basilar tip aneurysm associated with an incidental coarctation of the aorta (CoA). The aneurysm was treated with endovascular coiling. Patients with CoA frequently harbour intracranial aneurysms at a young age. The occurrence of basilar tip aneurysm associated with CoA is extremely rare. The relevant literature on the subject is discussed.
