#1707701 Unruptured Giant Internal Carotid Artery Aneurysm Inducing Panhypopituitarism: A Case Report

Internal carotid artery aneurysms extending into the sellar region are a rare phenomenon, comprising only 1-2% of all intracranial aneurysms. Intrasellar aneurysms, while uncommon, can lead to hypopituitarism due to their mass effect, potentially resulting in severe complications such as lethargy, coma, arrhythmia, and even death. Therefore, we must be alert for it in patients with giant intrasellar aneurysm. We herein report a case of hypopituitarism caused by intrasellar aneurysm. Notably, hypopituitarism triggered by aneurysmal compression may persist, and post-surgical restoration of pituitary function poses significant challenges, often necessitating long-term hormone replacement therapy,
