甲状旁腺腺瘤的CT诊断

CT diagnosis of parathyroid adenoma

目的探讨甲状旁腺腺瘤的CT表现,提高对甲状旁腺腺瘤的认识水平。方法对临床及手术病理证实的甲状旁腺腺瘤3例的CT表现和临床资料作回顾性分析。结果3例甲状旁腺腺瘤CT显示均位于甲状腺下方食道气管隐窝区,右侧2例,左侧1例。肿瘤呈卵圆形,边缘光滑完整,大小2～4cm,平均2.3cm,密度均匀,呈明显强化。3例均合并纤维囊性骨炎,1例合并肾结石。结论CT可准确显示甲状旁腺腺瘤的部位,大小、形态及其并发症,对临床治疗具有重要意义。

Objective To investigate the CT features of parathyroid adenoma and improve the understanding of the disorder. Methods CT images and clinical data of 3 cases of parathyroid adenoma proved by clinic and pathology were retrospectively studied. Results All adenomas were located at esophagotracheal recess （2 on lhe right side and 1 on left side）. The adenomas were oval, well demarcated and homogeneous in density, sized 2 to 4cm （2.3cm on average） in diameter,the adenoma were strongly enhanced after the contrast agent was given. Fibrecystosteitis were complicated in all 3cases, while renal stone was found in 1 case. Conclusion CT can precisely assess the location, shape, size and the complication of parathyroid adenoma, which is valuable for clinical management.
