title: Intraneural ganglion of the common peroneal nerve.
abstract: The authors report a fifteen-year-old patient with an intraneural ganglion cyst of the common peroneal nerve, with paralysis of the anterior tibial muscles which was subacute in onset. The lesion was radically removed using microtechniques. Such a purely intraneural location has rarely been described. The use of the surgical microscope and pathological study of the peroneal articular branches allows one to reject the possible synovial origin of this lesion. The different hypotheses regarding aetiology are discussed, as well as the possible lines of treatment.
