| 目的 探讨特发性甲状旁腺功能减退症的颅脑MRI表现。方法 回顾性分析27例特发性甲状旁腺功能减退症的颅脑MRI,观察病灶的位置与分布、形态及信号特点。结果 27例颅脑MRI表现为双侧基底节区片状对称性异常信号,21例双侧丘脑、齿状核片状异常信号,9例双侧放射冠-半卵圆中心见片状对称性异常信号;27例T1WI上见高信号区,其中4例基底节区病灶内见小片状低信号;26例T2WI及T2-FLAIR见高或稍高信号,1例见稍高、低混杂信号。结论 特发性甲状旁腺功能减退症的颅脑MRI表现具有一定特征性,双侧基底节区、丘脑及齿状核对称短T1稍长T2异常信号具有很高的诊断价值。 |

| Objective To assess the MRI features of cerebrum in idiopathic hypoparathyroidism (IHP). Methods MR images of 27 IHP patients were analyzed retrospectively emphasized on the location, appearance and signal intensity of the lesions. Results MRI showed symmetric abnormal signals in basal ganglia in 27 patients, in thalami and dentate nucleus in 21 patients, and in corona radiata-centrum ovale in 9 patients. All the lesions were hyperintensity on T1WI. Local hypointensity in basal ganglia was found in 4 patients, while hyperintensity or slight hyperintensity on both T2WI and T2-FLAIR were found in 26 patients, and slight hyperintensity with hypointensity on both T2WI and T2-FLAIR in 1 patient. Conclusion MRI of IHP has some features. Symmetric high signals on both T1WI and T2WI in basal ganglia, thalami and dentate nucleus have important diagnostic value for IHP. |
