The aim of this study was to investigate the MRI features and classification of 23 fetal hepatic hemangioendothelioma (HAE) and to compare the prognosis of HAE-I and HAE-II. The results showed that fetal HAE-I tends to be more vascular in the lesion, and the larger the focus, the more prone to complications. Once complications occur, the prognosis is poor; however, in HAE-II, the lesions are always smaller, there is a lack of vascularity, they are homogeneous, and the prognosis is good. Our study demonstrated that the MRI features and classification of HAE can effectively predict and guide prognosis.
