Bony outgrowth is seen arising from left proximal fibular metaphysis, directed away from the epiphysis posterolaterally. Lesion shows relatively uniform cartilage cap measuring approx. 2.7mm in maximum thickness. It is compressing / mildly splaying peroneus longus and soleus muscles anteriorly, posteriorly respectively.
Common peroneal nerve is compressed, splayed at lateral / posterior aspect of the lesion with edema in tibialis anterior muscle in mid / distal leg.
Case Discussion
Above findings are suggestive of fibular osteochondroma with compression of common peroneal nerve causing denervation edema in tibialis anterior muscle.
