Cystic lesions of peripheral nerves: Are we missing the diagnosis of the intraneural ganglion cyst?

Figure 12 The intraoperative images of one of these patients. A: Surgical exposure and decompression of the CPN in a 9-year-old girl presenting with foot drop. The intraoperative picture shows a thickened CPN (thick block arrow); the sural communicating branch of the CPN (thick hollow arrow); the articular branch of the CPN (thin block arrow) and the arthrotomy of the PTF joint and a mucinous cyst within it (thin hollow arrow); B: Close up of the CPN, being decompressed with multiple stab incisions with mucin (hollow arrow) within the substance of the nerve. The superficial peroneal branch of the nerve (block arrow) appeared unaffected which correlated clinically. PTF: Proximal tibiofibular; CPN: Common peroneal nerve.
