摘　　要：目的 探讨胃异位胰腺、神经鞘瘤、平滑肌瘤MSCT的表现。方法 回顾性分析经病理证实的10例胃异位胰腺、11例胃神经鞘瘤和11例胃平滑肌瘤的临床特征、病变发生部位及MSCT表现。结果 3组病例在发病年龄、发生部位、病灶形态及动态增强CT扫描上均具有一定差异,胃异位胰腺以中年男性胃窦粘膜下多见,部分病灶可以合并脂肪变;胃神经鞘瘤以中老年女性胃体多见、部分跨胃腔内外生长,少数病灶可以合并钙化;胃平滑肌瘤以中老年男性胃底粘膜下。病灶形态胃异位胰腺以扁平状多见,神经鞘瘤以类圆形多见,长短径比值差异有统计学意义,胃平滑肌瘤介于两者之间。动态增强扫描异位胰腺及神经鞘瘤明显强化,平滑肌瘤中度强化,差异有统计学意义;异位胰腺延迟期强化程度减退,神经鞘瘤持续性强化。结论 MSCT扫描及后处理技术可以清晰显示病变发生位置、病变形态、大小及病灶内部细节如脂肪变等,动态增强扫描三者强化程度及方式各异,对于三者的鉴别具有很高的价值。Objective To evaluate the value of CT differential diagnosis of gastric ectopic pancreas,gastric schwannoma and gastric leiomyoma. Methods 10 patients with gastric ectopic pancreas, 11 patients with gastric schwannoma and 11 patients with gastric leiomyoma which underwent CT scan and then were proved by pathology. To analyze the clinical characteristics, pathological location and Ms CT features of all cases. Results There were differences in age, location, shape and dynamic contrastenhanced CT scan among the three groups. Gastric heterotopic pancreas was mostly seen under the submucosa of gastric antrum in middle-aged men, there was fat tissue in four patients. Gastric neurinoma wad mostly seen in the gastric body of middle-aged and old women, duplex growth in 4 cases and calcification was found in 1 case. Gastric leiomyoma was mainly under the gastric fundus mucosa in middle-aged and old men. The heterotopic pancreas of stomach wad mostly flat, and the schwannoma was mostly round, there was significant difference of the ratio of long and short diameter. The ratio of gastric leiomyoma between the two. Dynamic contrast-enhanced scan showed significant enhancement of heterotopic pancreas and schwannoma, moderate enhancement of leiomyoma, and difference between them were significant. Conclusion Ms CT scanning and postprocessing technology could clearly show the location, shape, size and internal details of the lesions, such as steatosis. Dynamic contrast-enhanced scanning had different degrees and ways of enhancement, which wad of great value for the identification of them.
