摘　　要：目的探讨食管小细胞未分化癌的临床影像学特点。方法回顾性分析35例经病理检查证实的食管小细胞未分化癌的临床及影像学资料,所有病例均行X线双对比食管造影检查,其中20例进行了CT检查。结果35例患者中原发于颈段2例,胸食管上段4例,胸食管中段19例,胸食管下段10例。肿瘤大体类型及X线表现多数为髓质型及蕈伞型。病变范围大多数较长,≥5 cm 22例占63.2%。淋巴结、内脏转移多见,20例CT检查患者中,17例发现有淋巴结转移,5例远处脏器转移。结论食管小细胞未分化癌是高度恶性肿瘤,CT检查对淋巴结及内脏转移具有重要的诊断价值,联合临床及X线等影像学检查有助于临床分期和掌握手术适应证。Objective To evaluate the clinical and radiographic findings of primary small cell carcinoma of the esophagus. Methods 35 patients with pathologically proved primary esophageal small cell carcinoma were retrospectively analyzed. All patients underwent double - contrast esophagography, and CT was performed in 20 patients. Results Of the 35 patients, the primary tumor was located in the cervical esophagus in 2 patients, upper thoracic in 4, middle thoracic in 19, and lower in 10. Gross specimen and X - ray finding were mainly medullary and fungating types . The range of lesions was longer then 5em was 63.2% , metastasis was common. CT showed lymph nodes metastasis in 17/20 （ 85% ） cases, viscera metastasis in 5/20 （ 25% ） cases. Conclusion The clinical and X - ray findings of small cell carcinoma of the esophagus were similar to sequamous and adenocarcinoma . The CT was useful in diagnosis for lymph nodes and viscera metastasis, combined with clinical and X - ray finding will help to master the clinical stage and surgical indication.
