Giant anterior communicating artery aneurysm with intrasellar extension

Abstract

Introduction: Aneurysms extending into the sella are uncommon with only a few cases reported till date. Most of these arise from either the supraclinoidal or infraclinoidal segments of the internal carotid artery. Research question: Can Anterior communication artery aneurysm present with hypopituitarism due to compression of pituitary gland? Materials & methods: Case report and literature review. Results: We discuss this rare presentation in a middle-aged patient its surgical management and the follow-up course with a review of available literature. Discussion & conclusion: Anterior communicating artery aneurysms extending into the sella are extremely uncommon with only 4 cases reported in literature. They are usually giant aneurysms which are partially thrombosed with presenting with predominantly with mass effect in this case visual impairment and hypofunction of the pituitary.
