Sudden onset of severe headache is the most common presentation of a ruptured intracranial aneurysm. Similar symptoms can be caused by pituitary apoplexy, and radiological examination is needed to distinguish between the two. Development of infarction and/or haemorrhage of the hypophysis with concomitant unruptured cerebral aneurysm has been described. However, intratumoural aneurysm within a pituitary adenoma presenting with the ictus of both pathologies is extremely rare.
