Abstract

Trevor's disease, also known as dysplasia epiphysealis hemimelica, is a rare developmental disorder presented with epiphyseal overgrowth involving one or multiple epiphyses. Here we report the radiologic findings of two cases of dysplasia epiphysealis hemimelica in a 4-year-old boy in the knee without symptom and a 10-year-old boy in the ankle with pain. The former was observed for eight years and the latter was treated with surgical resection.

  Fig. 1 4-year-old man with Trevor's disease in the right distal femur. A. Initial oblique (A) radiograph shows multiple calcific foci in the postero-medial aspect of the epiphysis of the right distal femur (arrow). B. Sagittal sonography (B) shows epiphyseal cartilaginous overgrowth, containing multiple echogenic foci (arrow). C-E. Axial T2-weight image (C), axial T1-weight image (D) and axial enhanced T1-weight image (E) show the presence of asymmetric epiphyseal cartilaginous overgrowth (small arrows), which contain multiple ossifications, in the postero-medial aspect of the distal femur (arrows).

• 

  Fig. 2 4-year-old man with Trevor's disease in the right distal femur. Follow-up oblique radiographs after 12 months (A), 24 months (B), 54 months (C) and 8 years (D) show that calcific foci are maturated and becomes confluent with the epiphysis of the distal femur (arrows).

• 

  Fig. 3 4-year-old man with Trevor's disease in the right distal femur. Follow-up after 8 years, axial T2 weight image (A) and coronal T1 weight image (B) show normal bone contour and signal intensity in the distal femur with disappearance of the dysplasia epiphysealis hemimelica findings.

• 

  Fig. 4 10-year-old man with Trevor's disease in the left talus. Initial AP radiograph (A), unenhanced axial (B) and coronal (C) CT show irregular ossified mass, arising talus, in the antero-lateral aspect of the talus (arrows).

• 

  Fig. 5 10-year-old man with Trevor's disease in the left talus. Follow-up study after 2 years due to recurred ankle pain, oblique radiograph (A), unenhanced axial (B) and coronal (C) CT show recurred mass in the antero-lateral aspect of the talus (arrows).
