目的探讨消化道间质瘤(GIST)的临床影像学特点。方法对21例病理证实的消化道间叶源性肿瘤的X线钡剂造影及CT影像表现及鉴别诊断进行回顾性分析。结果21例消化道间质瘤中发生于食管1例,胃15例,小肠3例及结肠2例。X线钡剂造影:6例显示黏膜变平、撑开或移位,8例表现为充盈缺损,2例显示为外压性改变。CT检查:腔内外生长之肿块密度均匀者12例,内见液化坏死区6例,肿瘤内钙化者2例。增强扫描肿块均有显著强化,17例肿瘤不均匀强化或外围性强化,3例较均匀强化。结论消化道间叶源性肿瘤中以GIST最常见,CT检查在术前诊断中有重要价值。
Objective To investigate the clinical imaging features of gastrointestinal stromal tumors (GIST). Methods A retrospective analysis of 21 cases of pathologically confirmed gastrointestinal barium source radiography and CT imaging features and differential diagnosis of retrospective analysis. Results In 21 cases of gastrointestinal stromal tumors, one case occurred in esophagus, 15 cases in stomach, 3 cases in small intestine and 2 cases in colon. X-ray barium angiography: 6 cases showed mucosal flattening, distraction or displacement, 8 cases showed filling defect, 2 cases showed changes in external pressure. CT examination: the growth of lumen inside and outside the mass density in 12 cases, see liquefaction and necrosis in 6 cases, 2 cases of intracranial calcification. Enhanced scan mass were significantly enhanced, 17 cases of heterogeneous tumor enhancement or peripheral enhancement, 3 cases more evenly enhanced. Conclusions GIST is the most common type of gastrointestinal mesenchymal tumor, and CT is of great value in preoperative diagnosis.
