目的：分析和总结甲状腺髓样癌的 CT 特点。方法回顾性分析经手术病理证实的30例甲状腺髓样癌患者的 CT 表现。结果30例髓样癌中,单发25例(83.3%),多发5例(16.7%)。形态不规则27例(90.0%),边界不清楚26例(86.7%)。病灶不均匀强化伴内部不规则低密度区27例(90.0%),4例(13.3%)可见钙化。4例(13.3%)侵犯气管。29例行淋巴结清扫术,26例证实淋巴结转移(89.7%)。淋巴结边缘清楚12例(46.2%),边缘毛糙14例(53.8%),5例(19.2%)可见钙化。转移淋巴结表现为不均匀强化背景下散在不规则低密度区(100.0%)。结论髓样癌CT特点为不均匀强化伴内部不规则低密度区,转移淋巴结表现为强化背景下散在不规则低密度区,熟悉髓样癌的影像表现有助于提高术前诊断准确性。

Objective To analyze and summarize the CT features of medullary thyroid carcinoma (MTC).Methods 30 patients with MTC proved by surgery and pathology were scanned by CT.And the CT manifestations were analyzed retrospectively.Results In a total of 30 patients,a single lesion in 25 (83.3%)patients and multiple ones in 5 (16.7%)were found with irregular shape in 27 (90.0%),unclear border in 26 (86.7%),heterogenous enhancement with irregular internal hypodensity in 27 (90.0%),cal-cifications in 4 (13.3%)and invasion of trachea in 4 (13.3%).As for the 29 patients underwent the neck surgery ,26 (89.7%) were pathologically confirmed with lymph nodes metastasis.CT showed the metastatic lymph nodes with well-defined border in 1 2 (46.2%)and ill-defined one in 14 (53.8%),calcifications in 5 (19.2%)and heterogenous enhancement with irregular internal hy-podensity in all (100.0%).Conclusion CT features of MTC and metastatic lymph nodes appeared as heterogenous enhancement with irregular internal low attenuation area,which can improve the accuracy of preoperative diagnosis.
