【摘要】 目的探讨MSCT对肝脏转移性间质瘤的诊断价值。方法回顾性分析18例经临床及病理证实的肝脏转移性间质瘤的MSCT资料。结果 18例中,原发灶位于食管下段1例,胃8例,小肠7例,肠系膜1例,腹膜后1例;其中多发16例,单发2例;15例为囊实性,壁厚薄不均,3例为实性;肿瘤呈圆形或类圆形,最大径8～150mm;平扫17例呈不均匀较低密度,边界相对较清晰,1例出现不均匀钙化;增强强化不均匀,9例明显强化,7例中等强化,2例轻度强化;15例囊实性肿瘤中央可见未强化坏死区。结论肝脏转移性间质瘤常多发,大小不等,边界相对清晰,少有钙化;多数肿瘤内部可见低密度坏死囊变区,增强以明显强化或中等强化多见,MSCT对其诊断具有重要价值。更多还原

【Abstract】 Objective To assess the diagnostic value of multi-slice computed tomography(MSCT) for hepatic metastatic gastrointestinal stromal tumors.Methods The MSCT findings of 18 cases of hepatic metastatic gastrointestinal stromal tumors confirmed by histopathological examinations were retrospectively analyzed.Results Among 18 cases,the tumor originated from esophagus in 1 case,from stomach in 8 cases,from small bowel in 7 cases,from mesentery in 1 case,from posterior-peritoneum in 1 case.Sixteen cases were multiple tumors and 2 were single tumor;15 cases were cystic tumors and 3 were solid tumors.All tumors were round or oval,the maximal diameter was 8～150 mm.In plain scan,17 cases showed heterogeneous low density,1 case showed calcification.Most tumors showed heterogeneous intensity in contrast enhancement and 15 cases showed necrosis in the center of tumors.Conclusion MSCT has important value for the diagnosis of hepatic metastatic gastrointestinal stromal tumors.更多还原
