Carotid-ophthalmic aneurysmを伴うPituitary apoplexyの1例

Pituitary Apoplexy with An Unruptured Carotid-ophthalmic Aneurysm

I．はじめに

　報告により発生頻度に差はあるが，pituitary apoplexyはそれほど稀な現象ではない．また下垂体腫瘍が脳動脈瘤を合併することもそれほど稀ではない．しかし，脳動脈瘤を合併している下垂体腫瘍がphuitary apoplexyで発症することは極めて稀である．著者らは最近，非破裂carotid-ophthalmic aneurysmを伴い，くも膜下出血で発症したpituitary apoplexyの1例を経験したので報告する．

The association of pituitary adenoma and adjacent cerebral aneurysm is not uncommon and acute hemor-rhage into a pituitary adenoma is also a well recognized condition. However, the simultaneous occurrence of pituitary apoplexy with intracranial aneurysm is very rare. Such a case demonstrates the diagnostic diffi-culty in distinguishing between pituitary apoplexy and rupture of an aneurysm. We reported a patient with subarachnoid hemorrhage in whom a hemorrhage into the pituitary adenoma and a carotid-ophthalmic aneurysm was proven, and discussed the differential diagnosis and treatment.
