摘 要:报告甲状旁腺机能减退症(简称甲旁减)24例,其中特发性甲旁减10例,手术后继发性甲旁减2例,假性甲旁减10例,假假性甲旁减2例,并结合临床、血生化改变和CT进行分析。结果发现本病临床表现多样化,CT以颅内多发性对称性钙化为特点,且钙化数目与病程有关。四型的鉴别有赖于临床及血生化检查。 关键词:甲旁减 假性甲旁减 脑CT

Abstract:24 cases with hypoparathyroidism were reported, of them,10 cases were idiopathic hypoparathyroidism,2 post-thyroidectomy complicated with hypoparathyroidism,10 cases pseudohypoparathyroidism and 2 cases pseudo-hypoparathyroidism.An analysis on their clinical and blood biochemical changes and brain CT scans was carried out. The results show that the clinical manifestations of the disease are varied. The characteristics of brain CT scans are multiple symmetrical intracranial calcifications and the numbers of calcification are related to the course of the disease.The differential diagnosis of four types depends on the clinical and blood biochemical examination. Key words:Hypoparathyroidism Pseudohypoparathyroidism Brain CT▲
甲状旁腺机退减退症(简称甲旁减)是以多种神经精神症状和低血钙为特点的临床综合征。随着脑CT在临床的广泛应用和血生化检查手段的进步,其检出率有很大的提高。近10年我们共收治甲旁减24例,现报告如下,并结合文献进行讨论。
临床资料
一般资料:本组24例,男15例,女9例;年龄9~64岁,平均25.8岁;发病距做脑CT扫描时间:2周~10年;其中2例有甲状腺手术史。24例如下:特发性甲旁减10例,手术后继发性甲旁减2例,假性甲旁减10例,假假性甲旁减2例。 临床资料:癫痫发作18例,占75%,均为强直-阵挛发作,2例合并有复合部分发作;10例有手足搐搦病史;2例有肢体不自主震颤,此外还有肢体麻木、视乳头水肿、共济失调、神经衰弱综合征及兴奋、焦虑等神经精神症状。5例智能低下,韦氏智商14~86分。4例有体态和/或骨骼异常,如身材矮小、头尖、掌庶骨短等。 血生化检查:24例病人均做了血钙、血磷测定,其中11例做了甲状旁腺激素(PTH)测定,10例做了降钙素(CT)检查,结果见附表。
