目的 探讨胃平滑肌瘤(Gastric Leiomyoma)的CT特征。方法 回顾性分析 经手术病理证实、长径≥1cm的26例胃平 滑肌瘤的CT资料。结果 26例胃平滑肌瘤 中，24例位于贲门且累及胃食管连接部 (esophagogastric junction, EGJ)，2例 位于胃体。22例呈腔内生长，1例腔外生 长，3例呈腔内外生长。22例瘤体长径与 胃壁平行。20例形态规则，6例形态不规 则。26例瘤体密度均匀，增强扫描均呈 轻度均匀强化。结论 直径大于1cm的胃平 滑肌瘤多位于贲门且累及EGJ，沿胃壁生 长，密度均匀，增强扫描轻度均匀强化。

Objective To investigate the CT findings of gastric leiomyoma. Methods Retrospective analysis for CT data was carried out in 26 patients with gastric leiomyoma (long diameter≥1cm) that was confirmed by surgical pathology. Results Among 26 cases of gastric leiomyoma, the tumor in 24 cases was located at cardia with esophagogastric junction (EGJ) involvement, 2 at gastric body.The tumor showed endo-luminal growth in 22 cases, extra-luminal growth in 1 cases and duplex growth in 3 cases. The long diameter was parallel to the gastric wall in 22 cases. the shape of tumor was regular in 20 cases and irregular in 6 cases. The density of tumor was homogeneous in 26 cases, all showing slightly homogeneous enhancement in the enhancement scan. Conclusion Most gastric leiomyoma with diameter＞1 cm was located at cardia and involved the EGJ, cling-to-wall growth with homogeneous density，the enhancement scan showed slightly homogeneous enhancement.
