CT在食管平滑肌瘤诊断和鉴别诊断中的价值

The Value of CT in Diagnosis and Different Diagnosis of Esophageal Leiomyoma

目的 回顾总结 1 7例术前食管钡餐造影考虑食管平滑肌瘤的CT扫描 ,探讨CT对食管平滑肌瘤在诊断和鉴别诊断中的价值。方法 平滑肌瘤 1 0例 ,食管囊肿 1例 ,支气管囊肿 1例 ,纵隔淋巴结核 2例 ,结节病 1例 ,另 2例为迷走右锁骨下动脉。复习分析所有病例的食管钡餐造影和CT检查。结果 所有病例食管钡餐均见圆形或卵圆形充盈缺损。食管平滑肌瘤CT显示食管一侧壁软组织结节或肿块 1～ 4cm大小 ;两例囊肿性病变 ,呈低密度结节 ;结节病及淋巴结核者可见纵隔多发淋巴肿 ;CT清楚显示迷走血管的血管结构。

Purpose To investigate the value of computed tomography in diagnosis and different diagnosis of suspected esophageal leiomyoma. Methods 17 patients suspected esophageal leiomyoma with barium esophagogram were examined by CT. The diagnosis was based on histopathologic findings: leiomyoma ( n =10),esophageal duplication cyst ( n =1),bronchogenic cyst ( n =1),TB lymphadenopathy ( n =2),sarcoidosis ( n =1),aberrant right subclavian artery ( n =2). CT and barium esophagogram were compared and analysis. Results All 17 cases showed round or elliptical filling defects on esophagogram. On CT scans there was soft tissue nodule or mass(1～4cm in Diameter) of esophageal wall in all patients with leiomyoma. Two cystic lesions showed lower attenuation nodules. There were multiple mediastinal lymphadenopathys in the cases with sarcoidosis or tuberculosis. CT clearly displayed the abnormal vessels in the cases of aberrant right subclavian artery. Conclusion CT is valuable in improving ability of different diagnosis of esophageal leiomyoma. [
