目的探讨胃憩室的CT表现。资料与方法回顾性分析经手术病理证实的10例胃憩室的临床和CT特征。结果10例单发憩室位于贲门附近6例,胃体小弯侧2例,肾上腺区1例,胃窦1例。憩室直径2～10cm。CT平扫示含气-液平面囊性肿块6例、对比剂填充肿块1例、呈不均匀软组织肿块2例,含气软组织肿块1例。7例增强检查,4例呈典型薄壁肿块,1例肾上腺区不均匀强化肿块,1例先天性胃憩室合并腺癌呈胃底贲门区憩室壁不规则增厚,1例胃憩室合并胃肠间质瘤(gastrointestinal stromal tumor,GIST)呈胃小弯侧憩室口部和内侧壁局限性增厚。结论CT能提示胃憩室的诊断,明确诊断有时需要上消化道钡餐或内镜检测。
Objective To investigate the CT findings of gastric diverticulum. Materials and Methods Retrospective analysis of 10 cases of gastric diverticulum confirmed by surgery and pathology clinical and CT features. Results 10 cases of single diverticulum located in the vicinity of the cardia in 6 cases, 2 cases of gastric lesser curvature side, 1 case of adrenal gland, 1 case of antrum. Diverticulum diameter 2 ~ 10cm. CT scan showed 6 cases of gas-liquid cystic mass, 1 case of contrast-filled mass, 2 cases of uneven soft tissue mass and 1 case of soft-tissue mass. 7 cases of enhanced examination, 4 cases showed a typical thin-walled mass, 1 case of uneven enhancement of the adrenal mass, 1 case of congenital gastric diverticulum with adenocarcinoma was gastric cardia diverticulum wall irregular thickening, 1 case of gastric diverticulum with gastrointestinal The gastrointestinal stromal tumor (GIST) presents a localized thickening of the mouth and medial wall of the diverticulum in the lesser curvature of the stomach. Conclusion CT can prompt the diagnosis of gastric diverticulum, a clear diagnosis sometimes need upper gastrointestinal barium meal or endoscopy.
