Posterior temporal haematoma associated with anterior communicating artery aneurysm rupture.

We report the case of a 68-year-old man who presented with symptoms suggesting an intracranial haemorrhage. A computed tomography scan showed subarachnoid haemorrhage associated with a remote posterior temporal intracerebral haematoma. Angiography revealed the presence of an anterior communicating artery aneurysm, which was subsequently clipped. Possible causes for the association of a distant intracerebral haematoma with rupture of an anterior communicating artery aneurysm are discussed. This uncommon association should be recognised to avoid incorrect identification of the origin of haemorrhage.
