MRI
After a plain radiograph, MRI was performed.
Multiple exostoses of the proximal and distal femora, as well as the proximal tibiae and fibulae. The largest left sided exostosis is seen posteromedially in the distal femoral metaphysis in the coronal and axial T1W MRI images. The hamstring and pes anserine muscles and popliteal neurovascular structures are displaced by this large exostosis. The cartilaginous cap measures 4mm thick, as seen in the axial T2W MRI image.
