摘要
目的:探讨食管平滑肌类肿瘤的影像学诊断。方法:回顾分析46例手术病理证实的食管平滑肌类肿瘤的临床、X线、CT资料。结果:46例中良性38例,恶性8例,良性病变大小在1～6cm之间,恶性病变在4～12cm之间;X线检查:良性病变呈圆形或椭圆形充盈缺损,侧面呈弧形、半圆状充盈缺损,病变与食管壁的夹角多呈钝角,其表面粘膜皱襞展平消失,部分有单发或多发性小溃疡;恶性病变正面呈不规则圆形或椭圆形,其表面粘膜破坏,有多发溃疡形成,相应部位腔外有软组织影。CT扫描:良性表现为管腔内外软组织影,密度均匀,边缘光整,恶性表现为管腔内外软组织影,密度不均匀,边缘不光整,有分叶,强化时有边缘强化征象。结论:X线钡餐检查与CT扫描结合应用能提高食管平滑肌类肿瘤的诊断正确率及其良恶性的鉴别能力。
Objective: To investigate the imaging diagnosis of esophageal leiomyoma. Methods: The clinical symptoms as well as X-ray and CT appearances of pathologically proved esophageal leiomyoma in 46 patients were reviewed. Results: In 46 cases 8 patients had malignant lesions, while 38 patients had benign lesions. The size of benign lesions was 1～6cm, the size of malignant lesions was 4～12cm. Benign lesions showed round filling defect in A-P position, arc-shaped filling defect in lateral view on X-ray imaging. The angle between lesion and the wall of esophagus was mainly obtuse. The surface mucosa of esophagus at the lesion was flattened and disappeared, yet there were solitary or multiple ulcers among some patients. Benign leiomyoma of esophagus showed soft-tissue mass intrinsic or extrinsic to the esophageal wall with homogeneous density, regular margin, while the malignant lesion showed extrinsic soft tissue mass, inhomogeneous in density, irregular or multilobular margin on CT, the lesion edge enhanced after injection of contrast media. Conclusion: Combination of X-ray barium radiography and CT will improve the diagnostic accuracy of esophageal leiomyoma and the ability in differentiating malignant from benign lesions.
