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 evluate the CT imaging features of hepatic inflammatory myofibroblastic tumor(HIMT), so as to improve its diagnostic accuracy. Materials and Methods: The clinical and CT imaging findings of 6 cases of HIMT which confirmed by pathology in our hospital were analyzed retrospectively, including 4 males and 2 females, aged from 48 to 59 years old, mean age was 43 years old. Pre- and post-contrast CT images were examined for all six cases. Results: Five of six cases were single lesion, the other one was multiple. Clear margin was in four cases and unclear margin in two cases. Three cases were located in the left lobe of liver, 2 cases were in the right lobe of the liver and 1 case was located both the left and right lobe. In the pre-contrasted enhancement CT scan, heterogeneous(n=2) or homogeneous(n=4) hypo-density were shown in six cases. No enhancement(n=2) or mild/moderate enhancement(n=4) was shown in arterial phase respectively. Delayed enhancement was shown in the portal phase(n=6) and the delayed phase(n=5). Moreover, on the arterial phase image, feeding artery were shown in one case, having patchy enhancement around it in one case. The dilatation of the intra-hepatic bile duct was seen in one case. Conclusion: The dynamic contrast enhancement CT features of HIMT are multiple characteristic, which correlate with its pathologic findings. But the final diagnosis relies on pathology and immunohistochemistry examination.
