【摘要】：目的:探讨肝脏炎性肌纤维母细胞瘤(HIMT)的CT表现,以提高对本病的认识。材料和方法:回顾性分析本院经病理证实的6例HIMT的临床资料及CT表现,其中男4例,女2例;年龄48~59岁,平均43岁。6例均行CT平扫及动态增强扫描。结果:6例中,5例单发,1例多发;边界不清4例,边界清晰2例;肝左叶3例,右叶2例,跨肝左、右叶1例。CT平扫均表现为低密度影,密度均匀者2例,密度不均者4例;动态增强扫描动脉期无明显强化2例,轻-中度强化4例;门脉期呈进一步中-重度强化6例,延迟期呈持续性强化5例,强化程度下降1例。另动脉期病变内见供血动脉1例,周围见斑片状异常强化1例;合并肝内胆管扩张1例。结论:HIMT的CT表现多样,动态增强扫描可充分反映病变的病理学特征,结合临床资料,应考虑到本病的可能;但最终确诊仍依赖于病理和免疫组织学检查。
[Abstract]:Objective: to investigate the CT findings of hepatic inflammatory myofibroblastoma (HIMT) in order to improve the understanding of the disease. Materials and methods: the clinical data and CT findings of 6 cases of HIMT confirmed by pathology in our hospital were retrospectively analyzed, including 4 males and 2 females, aged 4859 years with an average age of 43 years, all underwent plain CT scan and dynamic contrast-enhanced CT scan. Results among 6 cases, 5 cases had multiple solitary lesions, 4 cases had unclear border and 2 cases had clear boundary, 3 cases had Zuo Ye, 2 cases had right lobe, 1 case had transhepatic left, 1 case had right lobe, all showed low density, homogeneous density in 2 cases, and uneven density in 4 cases. There were no obvious enhancement in arterial phase in dynamic contrast enhanced scan in 2 cases, mild to moderate enhancement in 4 cases, moderate to severe enhancement in 6 cases in portal phase, persistent enhancement in 5 cases in delayed phase, and decrease in enhancement degree in 1 case. In the other stage, the donor artery was found in 1 case, the surrounding lesion in 1 case, and the intrahepatic bile duct dilatation in 1 case. Conclusion the CT manifestations of the disease are diverse and dynamic enhanced scan can fully reflect the pathological features of the disease. The possibility of the disease should be considered in combination with clinical data, but the final diagnosis still depends on the pathological and immunohistochemical examination.
