摘要
目的探讨甲状腺癌术后复发的CT表现并评价CT对其诊断价值。方法回顾性分析经手术及病理证实的30例甲状腺癌术后复发的CT表现。结果复发灶位于:残留的甲状腺组织内13例,已切除的甲状腺处12例,已清扫的淋巴结处复发5例;其中复发合并颈淋巴结转移11例。30例复发灶密度均低于甲状腺固有的密度,复发灶易累及周边结构:胸廓入口14例,喉部(甲状软骨、环状软骨、声带、杓会厌皱襞)8例,颈总动脉16例,气管19例和食管13例。结论CT能够诊断甲状腺癌术后有无复发;明确复发灶部位、大小、范围、形态、密度、累及器官和淋巴结转移情况。
Objective To explore the CT manifestations of recurrent thyroid carcinoma, and evaluate the value of CT diagnosis. Methods The CT foundings of 30 patients with recurrent thyroid carcinoma confirmed by surgery and pathology were analyzed retrospectively. Results The recurrence of 13 cases located in the remaining thyroid,12 cases in the thyroid resected bed,and 5 cases in the lymph node cleared bed.There were 11 cases with recurrent thyroid carcinoma and cervical lymph node metastases. The density of the neoplasms in 30 cases was lower than that of thyroid. The recurrent tumor invaded the following adjacent structures:14 cases in thoracic inlet,8 cases in larynx (thyroid cartilage, cricoid cartilage,vocal cord and aryepiglottic fold),16 cases in common carotid artery,19 cases in trachea and 13 cases in esophagus. Conclusion CT is of diagnostic value for recurrent thyroid carcinoma,and can depict the tumor features clearly, such as location,size,density and extension,as well as the involved organs and lymph node metastases.
