摘要
目的分析肝炎性肌纤维母细胞瘤的CT表现,提高影像诊断准确率。方法选择2013年1月至2018年8月南京医科大学附属南京医院8例经手术或穿刺病理确诊的肝炎性肌纤维母细胞瘤患者,其中男性4例,女性4例;年龄50~65岁,平均年龄57.5岁。行CT平扫及增强扫描,总结CT影像特点。结果 6例显示不均匀渐进性强化,以轻、中度强化为主,病灶中央部分强化程度低于边缘部分;1例呈门静脉期边缘轻度环状强化,1例显示不明显轻度分隔强化,另1例合并有门静脉左支闭塞,并于周围可见侧支循环产生。结论肝炎性肌纤维母细胞瘤的CT表现具有一定特点,但仍需与肝内恶性肿瘤相鉴别,确诊依靠肝穿刺或手术行病理学检查和免疫组织化学检查。
Objective To analyze the CT features of hepatic inflammatory myofibroblastic tumor, and improve the accuracy of imaging diagnosis. Methods From January 2013 to August 2018, 8 patients with hepatitis myofibroblastoma diagnosed by surgery or puncture pathology were enrolled, which included 4 males and 4 females, aged 50-65 years old with mean age of57.5 years old. The CT scan and enhanced scan were performed to summarize the characteristics of CT images. Results Six cases showed inhomogeneously mild and progressive enhancement, with focal central enhancement lower than margin. One case showed slightly ring-like enhancement on portal venous phase and 1 case exhibited slightly septal enhancement. Meanwhile, one case showed occlusive phlebitis of left portal vein with development of collateral circulation. Conclusion It is demonstrated the CT imaging of hepatic inflammatory myofibroblastic tumor has some characteristic features, but need to be differentiated from hepatic malignant tumors. The liver biopsy or surgery with pathology inspection could make the definite diagnosis.
