摘要
目的探讨甲状腺嗜酸细胞腺瘤(HCA)的MSCT表现。方法回顾性分析20例经手术和病理证实的HCA患者的MSCT及临床资料,并复习文献。结果 20例HCA患者中,10例病灶位于左叶,9例位于右叶,1例两侧叶均被累及。病灶大小0.6cm×1.3cm～4.0cm×5.2cm,形状呈圆形或卵圆形,边缘光滑,边界较为清楚,以实性成份为主。CT平扫呈不均匀低或等密度影,边界欠清;双期增强扫描,病灶实性部分均有不同程度明显强化,以动脉期强化为著,但较正常甲状腺及周围血管密度低,部分囊变区无强化。结论 MSCT表现结合相关的临床资料,对HCA的诊断有一定的提示作用,确诊依赖病理。
Objective To explore the multi-slice spiral CT（MSCT） findings of hurthle cell adenoma of the thyroid gland （HCA）. Methods The clinic data and MSCT findings of 20 cases with pathologically proven HCA were analyzed retrospectively. Results Among all 20 cases, 10 were located in left lobe, 9 cases were located in right lobe and one ease in both of two lobe. The sizes of adenomas ranged from 0.6 cm×1.3 cm～4.0 cm×5.2 cm. The shape of tumors were round or oval well-demarcated, and the boundary of tumous was clear. The solid part of mass showed isodense or hypodense on plain CT scan. And in the arterial and venous phase, it showed enhancement markedly with various degrees but lower than that of thyroid gland and adjacent blood vessels, cystic areas in the mass revealed no contrast enhancement. Conclusion Conbined the MSCT appearances with the relevant clinic data is useful for the diagnosis, but the final diagnosis depends on pathology.
