Endovascular treatment of intracavernous carotid aneurysm with hyperprolactinaemia

Abstract

A 42-year-old woman presented with headache, galactorrhoea, marked hyperprolactinemia and normal neurologic examination.CT MR and MR-angiography showed an intracavernous carotid artery aneurysm with minimal displacement of the pituitary stalk. Treatment by embolisation using GDC coils allowed exclusion of the aneurysm.Galactorrhoea resolved and serum prolactin levels fell to normal after eight months. Followup MR showed absence of the aneurysm, although the discrete mass effect persisted, suggesting that hyperprolactinaemia was due to pulsatility.
