Abstract: Objective To investigate the magnetic resonance imaging (MRI) characteristics and pathological features of hepatic epithelioid hemangioendothelioma (HEHE).Methods MRI characteristics and clinical data of 8 patients with pathologically diagnosed HEHE from March 2012 to May 2017 were retrospectively analyzed. All patients underwent MRI scan. MRI performance and the related pathology were analyzed by 2 senior physicians. Results All 8 HEHE cases manifested as multiple intrahepatic lesions, including 3 cases with lung metastasis and 1 case with both lung and vertebral metastasis. MRI revealed that intrahepatic lesions were hypointense on T1 weighted imaging but hyperintense on T2 weighted imaging. In dynamic contrast-enhancement, lesions showed progressive or ring enhancements. Signs of hepatic capsular traction and lollipop were also observed.Conclusion HEHE has some special MRI characteristics, which is still further confirmed by the pathology.
