MRI Findings of Dysplasia Epiphysealis Hemimelica: A Case Report

Dysplasia epiphysealis hemimelica, also known as Trevor's disease, is a rare disorder characterized by osteochondral overgrowth of one or more epiphyses and usually affecting the lower limbs. It typically presents in childhood, with painless swelling or deformity around the involved joint. We report a case of recurrent dysplasia epiphysealis hemimelica which presented as a large popliteal mass four years after excision of the initial lesion.
