Abstract

The occurrence of coincidental intracranial aneurysms with tumors of pituitary origin is very rare. Silent intracranial aneurysms located distant from the lesion to treated have little relevance to surgical management of most patients. However, aneurysms of the major arteries adjacent to pituitary and suprasellar mass are an additional hazard to surgical treatment. We experienced silent multiple aneurysms located just below the bifurcation of both internal carotid arteries associated with symptomatic pituitary adenoma(acromegaly). Transfrontal removal of the pituitary eosinophillic adenoma was carried out without treatment of the aneurysms. The angiographic data considered significant to the safety of the procedure. So the necessity of the cerebral angiography is stressed to show the precise relationships of vessels to masses in the pituitary region. Also the possible reasons for the occurrence of aneurysms in association with these tumors were discussed.
