case_images: Its size was approximately 36*35*120 mm (Figure 1).
case_images: (a) Blue arrow shows the proximal part of peroneal nerve compressed by the peroneal muscles, blue star shows the intramuscular septation; (b) White arrow points intact peroneal nerve after removal of disrupted muscle; (c) Disrupted peroneus longus muscle

case_images: The mass containing the surface of the peroneus longus muscle was excised from a total of 15 cm, while preserving the peroneal nerve and its branches (Figure 2).
case_images: (a) and (b) Preoperative coronal MRI section showing cyst recurrence. Red arrows indicates the PTFJ connection; (c) Axial MRI section of ganglion cyst recurrence. PTFJ: proximal tibiofibular joint

case_images: PTFJ arthrodesis was planned when the MRI revealed the ganglion cyst originating from the PTFJ (Figure 3).

case_images: Tibiofibular arthrodesis was achieved with a 3.5 mm cannulated screw (Figure 4).
