复发性喉癌CT诊断

目的：着重研究复发性喉癌的CT表现特征及诊断价值。材料和方法：对经活检/手术和病理证实的56例复发性喉癌CT资料进行回顾性研究。结果：本组56例复发性喉癌以术后多种喉部和颈部组织结构受侵为主要CT表现特征。喉旁不规则强化肿块23例,占40%;颈淋巴结肿大16例,占28.6%;喉软骨破坏3例,占5.3%;颈动脉鞘受累5例,占8.9%;颈椎骨质破坏2例,占3.6%;气管造漏口癌5例,占8.9%。结论：喉癌术后的定期CT复查,可及时发现复发性喉癌,能为临床诊断提供重要CT影像学信息。

Recurrent Laryngeal Carcinoma

Objective:Study of the CT features and its diagnostic value in recurrent laryngeal carcinoma.Materials and Methods:CT findings of 56 cases with recurrent laryngeal carcinoma proved by biopsy or operation were analyzed retrospectively.Results:There were 56 cases of recurrent laryngeal carcinoma having CT findings invaded by multiple laryngeal and neck structcres,palapharyngeal irregular intensified mass that have normal ovenlying mucosa of laryngeal cavity in 23 cases(40%),and are not detectable on endoscopy;ealaged cervical lymph nodes 16 cases(28.6%);thyroid cartilage/cricoid cartilage destraction 3 cases(5.3%);internal carotid artery and internal jugular vein involvement 5 cases(8.9%);cervical vertebral 2 cases(3.6%)and carcinoma of the orifice of tracheotomy in 5 cases(8.9%).Conclusion:CT Reexamination after operation with laryngeal carcinoma may be one of the importent method in early diagnosis of postoperative tumor recurrence and decision of appropriate treatment.
