摘　　要：目的分析肝脏炎性肌纤维母细胞瘤的影像学特点并分型。方法收集本院病理证实为肝脏炎性肌纤维母细胞瘤的患者22例,分析其影像学特点,并对其进行分型。结果 22例患者共发现23个病灶。肝脏炎性肌纤维母细胞瘤的典型影像特点包括晚期高强化(13/20)、中心坏死(12/23)及边缘包壳(12/23)。有核果型为最典型的形态学分型(8/23),其次为无核果型(7/23)。结论肝脏炎性肌纤维母细胞瘤多为单发结节样病变,病灶中心可见"虫蛀隧道"样坏死、边缘可见包壳、形似"有核果"为典型表现,晚期强化及边缘强化为其特征性表现。Objective To assess the radiological imaging findings of hepatic inflammatory myofibroblastic tumor and to discuss the appropriate morphological classification. Methods A total of 22 patients with hepatic inflammatory myofibroblastic tumor confirmed by pathology were enrolled. Imaging performance of hepatic inflammatory myofibroblastic tumor were analyzed and the lesions were classified into appropriate type based on the imaging findings. Results Totally 23 lesions were found in 22 patients. The typical imaging features included great enhancement at later phase （13/20）, moth-eaten central necrosis （12/23） and peripheral shell （12/23）. ＂Seed in fruit＂ was the most typical classification （8/23）, followed by ＂Seedless fruit＂ （7/23）. Conclusion Hepatic inflammatory myofibroblastic tumur typically shows as a single nodular lesion with moth-eaten necrosis and peripheral shell like a ＂Seed in fruit＂. The enhancement at later phase （especially the peripheral enhancement） can be regarded as a particular feature.
