Abstract
Sellar region aneurysms comprise a diverse group of cerebral aneurysms and may mimic the presentation of a cystic pituitary mass (cystic adenoma, craniopharyngioma, Rathke cleft cyst).
The repercussions of failure to diagnose an intrasellar aneurysm may be catastrophic. Fortunately, the advent of MRI and noninvasive vascular imaging (CT and MR angiography) has improved the ability to detect these lesions prior to any surgical intervention.
Most patients presenting with intrasellar aneurysms will have unruptured aneurysms that present secondary to mass effect on surrounding structures.
The most common signs and symptoms are headache, visual loss, endocrinopathy, hyponatremia, and cranial nerve paresis. Hyperprolactinemia and hypogonadism are the most common endocrinopathies associated with these lesions.
