目的探讨原发性肝细胞癌(HCC)在螺旋CT扫描中的不典型表现及其产生原因。方法选择17例HCC患者,其中男性14例,女性3例;年龄29～71岁,平均年龄52岁。分析经手术病理组织证实的螺旋CT扫描中呈不典型表现的CT征像和病理学改变。结果17例共发现18个病灶为不典型表现,其中10个病灶在动脉期强化明显,门静脉期和延迟期为等密度或高密度;6个病灶在动脉期、门静脉期和延迟期均呈低密度;2个病灶动脉期病灶边缘有环形强化,门静脉期和延迟期仍有持续强化。结论肝癌在螺旋CT 3期增强扫描中有多种不典型表现,病灶的血液供应情况、病理学基础等是其常见原因。
Objective To investigate the atypical manifestations and causes of primary hepatocellular carcinoma (HCC) in spiral CT scans. Methods Seventeen patients with HCC were selected, including 14 males and 3 females, aged 29-71 years with a mean age of 52 years. CT images and pathological changes of atypical CT findings confirmed by surgical pathology were analyzed. Results A total of 18 lesions were found in 17 cases, of which 10 lesions were markedly enhanced in the arterial phase. The portal vein phase and the delayed phase were isodense or high density. The 6 lesions showed low arterial phase, portal vein phase and delayed phase Density; two lesions at the edge of the arterial phase annular enhancement, portal venous phase and the delay is still continued to strengthen. Conclusions There are many atypical manifestations of liver cancer in the spiral CT three-phase enhanced scanning. The blood supply of the lesion and the pathological basis are the common causes.
