甲状旁腺机能减低脑部改变的CT评价

CT in the evaluation of cerebral changes due to hypoparathyroidism

目的:探讨甲状旁腺机能减低的病因、发病机制、脑部CT表现和鉴别诊断。方法:本文对11例甲状旁腺机能减低患者的临床和CT资料进行回顾性分析,全部病例均行平扫。结果:11例均显示对称性基底节钙化,钙化还可见于小脑齿状核、丘脑、侧脑室壁、中脑和大脑皮质下等区域,对称或不对称。结论:CT扫描能清楚显示甲状旁腺机能减低患者的脑内特征性的钙化,对本病的诊断具有很大的价值。

Objective： To investigate the etiology pathogenesis, CT findings of the brain and differential diagnosis of hypoparathyroidism. Methods： CT manifestations and clinical data of 11 cases with hypoparathyroidism were analysed retrospectively. Plain scan were taken in all cases. Results： Symmetrical calcifications in bilateral basal ganglia were found in all cases of this group. Symmetrical or non-symmetrical calcification were also found in bilateral dentate nuclei, thalami, walls of lateral ventricles, midbrain and cerebral subcortical areas. Conclusions： CT scan clearly showed specific calcifications in the brain of hypoparathyroidism and was valuable for diagnosing.
