Intrasellar Aneurysms

"Intrasellar aneurysms that mimic pituitary tumors with are rare with few previous reports. 10% of such aneurysms can cause parasellar syndromes and 1.4-5% of such cases managed by neurosurgeons have been found to extend into the sella tursica. They may present with symptoms of mechanical compression or endocrinopathies. Though absence of endocrine symptoms may distinguish an aneurysm from a pituitary adenoma in most cases, mass effect from an enlarged aneurysm may prove the opposite in rare cases. Though rare, it is quite possible to encounter a patient in the fertility or gynecology clinic with symptoms of hypopituitarism such as irregular periods or infertility. Presentations related to adrenal, thyroid and gonadal deficiencies are most commonly observed with visual impairment being one of the most common presenting symptoms. Most cases of intrasellar aneurysms are diagnosed either at the time of surgical exploration or via imaging, typically MR. Rupture of an intrasellar aneurysm is the most severe complication, which leads to intrasellar bleeding followed by subarachnoid extension. These aneurysms typically mimic pituitary tumors and potentially may have catastrophic outcomes if not appropriately recognized and managed.
