Abstract

Two cases of pituitary-dependent Cushing's syndrome are described in which the computed tomography (CT) examination was negative; as the hormone dynamic investigations were directed towards the presence of corticotropin (ACTH) secreting pituitary formations, magnetic resonance imaging (MRI) of the pituitary was performed, which evidenced the presence of such lesions; subsequent neurosurgery confirmed in both cases the location indicated by MRI. In conclusion, the higher sensitivity of MRI compared to CT in the diagnosis of ACTH secreting pituitary adenomas can be noted.

摘要

本文描述了两例垂体依赖性库欣综合征患者，其计算机断层扫描（CT）检查结果为阴性；由于激素动态检查旨在发现分泌促肾上腺皮质激素（ACTH）的垂体病变，因此对垂体进行了磁共振成像（MRI）检查，结果证实存在此类病变；随后的神经外科手术在两例患者中均证实了MRI所示的病变位置。总之，可以注意到MRI在诊断分泌ACTH的垂体腺瘤方面比CT具有更高的敏感性。
