Imaging of dysplasia epiphysealis hemimelica (Trevor's disease)

Abstract

Dysplasia epiphysealis hemimelica (DEH; synonyms; Trevor's or Trevor Fairbank disease) is a rare developmental disorder of the skeleton characterized by asymmetric osteochondral overgrowth of the cartilage of a medial or lateral epiphysis or epiphyseal equivalent. Imaging plays an important role in the diagnosis and management of DEH and in assessing the need for biopsy to differentiate it from more sinister diseases. There is no recent comprehensive review of the imaging of DEH and the purpose of this article is to describe the modern radiological manifestations of DEH.
