复发性喉癌的CT表现

CT Manifestations of Recurrent Laryngeal Carcinoma

目的 :探讨复发性喉癌的CT表现及其诊断价值。材料和方法 :回顾性分析经手术及喉镜病理证实的 2 2例喉癌术后复发的CT表现。结果 :复发灶位于残留的喉结构内 10例 ,已行全喉切除的喉床内 11例 ,已清扫的淋巴结处 1例 ,其中 12例并淋巴结转移。 2 2例复发灶密度均不均匀 ,且呈不均匀增强。复发灶累及胸廓入口 1例、甲状腺 10例、食管 7例、颈总动脉 13例和气管 3例。结论 :CT能够诊断喉癌术后有无复发 ,明确复发灶部位、大小、形态、密度、范围、累及器官及淋巴结转移情况。

Purpose:To explore the CT manifestations and evaluate the CT diagnostic value for the recurrent laryngeal carcinoma. Materials and Methods: 22 cases of recurrent laryngeal carcinomas,confirmed by surgery and pathology were analyzed retrospectively. Results:Local recurrence in the remaining larynx was found in 10 cases,in larynx-resected bed in 11 cases and in lymph node-cleared bed in 1 cases,12 cases of them had lymph node metastasis at the same time. On CT scan,all recurrent foci were inhomogeneous hyperdensity with inhomogeneous enhancement. Of 22 recurrent foci,one was found in thoracic inlet,10 in thyroid,7 in esophagus,13 in common carotid artery and 3 in trachea. Conclusion:CT scans can provide reliable images for diagnosis of recurrent laryngeal carcinoma,and clearly depict recurrent focal features,such as location,size,density and extension,as well as the involved organs and lymph node metastasis.
