Intra-operative findings were: i) a mass approximately 15x9x4 cm arising from the two heads of the gastronemius muscle at its origin in the popliteal fossa; ii) a yellowish-pink mass closely related to the posterior tibial artery at its origin in the fossa, the mass had to be dissected and removed piecemeal around the neurovascular bundle to prevent injury; iii) the soleus muscle had to be stripped off the gastronemius and the latter was detached at the gastrosoleus junction; iv) the cut surface of the mass was solid and yellowish with numerous ecchymotic patches (Figure 2).
