Abstract

Intracavernous internal carotid artery aneurysms can extend into the sella and simulate pituitary adenomas. Correct radiological differential diagnosis is fundamental. When treating intrasellar masses at the slightest suspicion of a nonpituitary origin, further workup should be considered. The possibility of a vascular lesion simulating a pituitary adenoma should always be evaluated by neurosurgeons and ear, nose, and throat surgeons operating in the sellar region. We report a case of intracavernous carotid aneurysm mimicking a pituitary adenoma and emphasize the need for a critical neuroradiological evaluation for correct diagnosis and to avoid a potentially life-threatening situation. Keywords: Carotid aneurysm; Pituitary adenoma; Differential diagnosis; Transsphenoidal endoscopic approach
