Pituitary dysfunction in adults are often associated with tumors of the gland and manifests with mass effects and hypopituitarism. MRI of pituitary region often provides confirmation of the diagnosis and assists in planning neurosurgery.
A 69 years old female evaluated for chronic headache was found to have a supra-sellar mass lesion that mimicked a pituitary tumor, with biochemical evidence of hypopituitarism. Cerebral angiogram confirmed the diagnosis of an aneurysm of the intracavernous internal carotid artery. She was successfully treated with coil embolization of the aneurysm and achieved resolution of symptoms and return of biochemistries to normal.
Carotid aneurysm can mimc pituitary tumours clinically and radiologically on MRI scan. This rare possibility should be considered in evaluating supra-sellar masses to avoid catastrophic consequences.
成人垂体功能障碍常与垂体肿瘤相关，表现为占位效应和垂体功能减退。垂体区域的磁共振成像（MRI）常有助于确诊，并辅助神经外科手术规划。
一名69岁女性因慢性头痛接受评估，发现鞍上有一占位性病变，疑似垂体肿瘤，并有垂体功能减退的生化证据。脑血管造影证实为海绵窦段颈内动脉瘤。她通过动脉瘤弹簧圈栓塞术成功治疗，症状缓解，生化指标恢复正常。
颈内动脉瘤在临床和MRI扫描上可模拟垂体肿瘤。在评估鞍上肿块时应考虑到这种罕见可能性，以避免灾难性后果。
