摘　　要：目的 探讨胃部异位胰腺的CT表现特点及MSCT对胃部异位胰腺的诊断价值.方法 回顾性分析本院37例经手术病理证实的胃部异位胰腺患者的临床及MSCT资料,患者扫描前均做好胃部充盈及低张准备,采用多层螺旋CT进行三期增强扫描及三维重建.从病变位置、大小、形态及强化方式分析该类病变的CT特点.结果 37例胃部异位胰腺病理切片所见均为正常胰腺组织,患者平均年龄为（47±1）岁,CT表现均为单发病灶,大小为0.8～4.7 cm,与胃壁呈广基底相连.18例（48.7％）发生于胃窦,29例（78.4％）起源于胃黏膜及黏膜下层,27例（73.0％）为卵圆形,18例（48.7％）的病变强化方式近似于正常胰腺组织.结论 胃部异位胰腺的CT表现有一定的特征,熟悉其特点有助于与胃部良恶性肿瘤相鉴别.Objective To investigate the multi slice spiral CT （MSCT） features and diagnostic value of gastric ectopic pancreas. Methods Clinical and MSCT data of 37 cases with gastric ectopic pancreas proved by pathology and surgery were retrospectively an- alyzed. After stomach filling and hypotonic preparation, patients underwent contrast-enhanced scanning with three phases and three- dimensional reconstruction. The location, size, shape and contrast enhancement pattern of lesions were analyzed. Results The path- ological findings of 37 cases were normal pancreatic tissue. The mean age of the patients was 47% 1 years. Solitary lesion connected with the stomach wall in a wide base was seen in all cases, and the size ranged from 0.8 to 4.7cm. 18 cases （48.7% happened in the gastric antrum, and 29 cases （78.4% ） originated in the gastric mucosa and submucosa. 27 cases （73.0%） were oval. Contrast- enhancement pattern was similar to that of the normal pancreatic tissue in 18 cases （48.7%）. Conclusion Gastric ectopic pancreas has certain CT characteristics. It can help to differentiate gastric ectopic pancreas from benign and malignant gastric tumors to famil- iar with these features.
