The co-existence of cerebral aneurysms and pituitary adenomas is rare. Here, we report a patient with a coexisting anterior communicating artery aneurysm and a pituitary adenoma and review the available literature concerning this phenomenon. There is a debate in the literature regarding any causal relationship between aneurysms and pituitary tumors, although there are many reports of aneurysms caused by trauma or radiation following treatment of pituitary tumors. These simultaneous lesions are best diagnosed with magnetic resonance imaging with magnetic resonance angiography. Craniotomy for simultaneous aneurysm clipping and resection of the pituitary tumor is the best treatment option.
