摘要
目的:探讨多层螺旋CT(MSCT)对甲状旁腺腺瘤的诊断价值。方法:回顾性分析10例经手术病理证实为甲状旁腺腺瘤的CT及临床资料。结果:10例甲状旁腺腺瘤均起源于下甲状旁腺,右侧4例,左侧6例,均位于气管食管沟内。肿瘤大小约0.9cm×1.0cm~3.0cm×8.0cm,呈圆形或卵圆形,边缘光滑完整。平扫肿瘤呈等密度,较正常甲状腺为低密度。增强后10例肿瘤均有不同程度强化,但均较周围血管密度及正常甲状腺密度低,增强后肿瘤呈均匀强化者8例,坏死不均匀强化者2例。结论:MSCT增强及三维重建检查可准确显示甲状旁腺腺瘤的部位、形态、大小及其与周围结构的关系,对临床手术有重要的指导意义。
Objective:To study the value of multi-slice spiral CT(MSCT) in diagnosis of parathyroid adenoma.Methods:Retrospective analysis was performed in clinical data and CT images of 10 cases of parathyroid adenoma proved surgically and pathologically.Results:All of the parathyroid adenomas were originated from the inferior pole of parathyroid gland with 4 cases at the right side and 6 cases at the left side.All located at the recess between trachea and esophagus.The sizes of adenomas ranged from 0.9 cm×1.0 cm^3.0 cm×8.0 cm.The tumors were round or oval,well-demarcated,iso-attenuated yet higher than that of thyroid gland on plain CT scan.After contrast medium administration,the adenomas revealed enhancement with various degrees but lower than that of thyroid and adjacent blood vessels.8 cases of adenomas were enhanced homogeneously,2 cases showed no enhancement in necrosis.Conclusion:The location,shape,size,and the relationship with surrounding structures of parathyroid adenoma could be precisely displayed on enhanced MSCT and 3D reconstruction,which is valuable for surgery.
