摘　　要：目的 :探讨食管平滑肌瘤的影像学诊断和鉴别诊断。方法 :回顾性分析经手术病理证实 2 4例食管平滑肌瘤的影像学表现。结果 :常规食管X线钡餐造影示腔内型 16例 ,表现为圆形或半圆形充盈缺损 ,腔外型 8例 ,表现为局部轻度受压。其中 2 1例行CT检查 ,显示圆形和椭圆形及马蹄型肿块 ,增强扫描呈均匀强化。 16例行MR扫描显示肿块 ,矢状位和冠状位肿块与食管关系密切。结论 :食管平滑肌瘤X线钡餐造影检查是首选检查方法 ,但有时定性诊断较难 ,CT与MRI扫描能确定肿瘤大小、范围、性质及与其他病变鉴别。Objective:To discuss imaging diagnosis and distinguish of esophagus leiomyoma.Methods:Analysis 24 cases imaging display of oesophagus leiomyoma with pathology provement.Results:16 cases intracavity type show with round or half-round filling defect on X-ray image,8 cases extra cavity type with light press partly in barium meal examine.21 cases are accepted with CT scanning showing round or half-round and hoof shape lump.16 cases are accepted with MR scanning,showing tumor is close connected to oesophagus on sagittal plane and coronal plane. Conclusion:X-ray examine is the first choice for oesophagus leiomyoma,but difficult for determing nature of tumor.CT and MRI scanning can not only confirm the size of tumor but also differentiate it from other cancer.
