目的分析6例儿童原发性肝细胞肝癌的MSCT特征,以期提高对该病的认识水平。方法回顾性分析6例经手术病理证实的儿童原发性肝细胞癌患者的MSCT检查资料,包括CT平扫及动态增强扫描图像,总结儿童原发性肝细胞肝癌的MSCT表现特点及鉴别要点。结果甲胎蛋白(AFP)阳性者3例,阴性1例,其余2例未做该项检查。CT平扫表现为腹部软组织密度肿块影,边界较清楚,密度不均匀,其中1例可见点状钙化。1例较均匀轻度强化,4例明显不均匀强化,1例明显均匀强化。2例肠系膜根部或腹主动脉旁淋巴结肿大。结论儿童原发性肝细胞肝癌的MSCT表现有一定的特征性,结合临床资料及生化检查,有助于提高儿童肝细胞肝癌的术前诊断率。
Objective To analyze the features of MSCT in 6 cases of primary hepatocellular carcinoma in order to improve the level of understanding of the disease. Methods A retrospective analysis of 6 cases of pathologically confirmed primary hepatocellular carcinoma in children with MSCT examination data, including CT scan and dynamic contrast-enhanced scan images, summarize the characteristics of children with primary hepatocellular carcinoma and MSCT features of the differential points. Results AFP positive in 3 cases, negative in 1 case, the remaining 2 cases did not do this test. CT scan showed abdominal mass density of soft shadow, the border more clearly, the density is not uniform, one case showed punctate calcification. 1 case was more uniform mild enhancement, 4 cases significantly uneven enhancement, 1 case was significantly enhanced. 2 cases of mesenteric lymph nodes or abdominal aortic lymph nodes. Conclusion MSCT of children with primary hepatocellular carcinoma has certain characteristics. Combined with clinical data and biochemical tests, it is helpful to improve the preoperative diagnosis rate of hepatocellular carcinoma in children.
