Double jeopardy - pituitary apoplexy complicated by ruptured aneurysm of the internal carotid artery within an adenoma: a case report.

Background: 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.

Emergency surgical removal of a migrated coil during embolization of a giant internal carotid artery aneurysm: illustrative case.

Background: Coil migration during endovascular treatment for an intracranial aneurysm is rare. When it occurs intraoperatively, it often mandates prompt endovascular retrieval or, as a salvage maneuver, microsurgical extraction if it fails endovascularly.

Observations: The authors presented a case of immediate coil migration during embolization of a giant intracranial cavernous segment of the internal carotid aneurysm.
