Objective To summarize the clinical and MRI features of epithelioid and non-epithelioid hepatic angiomyolipoma (Epi-HAML and non-Epi-HAML). Methods We retrospectively collected and analyzed 133 cases of liver surgery performed at Zhongshan Hospital of Fudan University and postoperative pathology confirmed as HAML during 2011-2018. According to pathological type，they were divided into Epi-HAML group and non-Epi-HAML group; and were divided into three sub groups: smaller than 3.0 cm， 3.0-5.0 cm and larger than 5.0 cm according to tumor diameter. We compared these groups by studying their MRI images，tumor markers and other blood tests. Results Most of the patients were diagnosed without specific symptoms(83.6%). Epi-HAML patients tended to show more symptoms compared with non-Epi-HAML patients (P<0.05). There was little difference between these two groups in age，gender, history of disease, or serum tumor makers.A total of 141 HAML lesions were discovered after surgery，87 were Epi-HAML and 64 were non-Epi-HAML. The differences of diagnosis accurateness, T2WI, diffusion weighted imaging（DWI), enhancement mode and fat component between the two groups were significant (P<0.05). When we grouped these lesions by tumor diameter (0.7-2.9 cm, 3.0-5.0 cm, 5.1-20.5 cm), the appearance of necrosis, cysts, hemorrhage, tumor vessels, early draining veins and perfusion disorders showed significant difference（P<0.05). Conclusion There are significant difference between the two groups of HAML in T2WI, DWI, enhancement mode and fat signal.The imaging features such as tumor vessels and early drainage veins are more prominent when the tumor diameter is larger than 5 cm.
