Cystic intraneural tumors filled with gelatinous material and referred to as "ganglions" are rare and may not be diagnosed without exploration.The patient, a healthy 49-year-old male, injured his right ankle in August, 1973, after which pain in the right calf and knee was developed. Shortly thereafter, the patient developed right footdrop.In March, 1973, the patient was admitted to our hospital. An EMG showed extensive denervation of the tibialis anterior. The peroneal nerve was normal on palpation preopeatively.When explored at surgery, the nerve was found to have a fusiform swelling with a nodular appearance. On incision of the nerve, clear gelatinous viscid material was identified and evacuated. Microscopic examination of portion of the cyst wall revealed no neoplasia. The patient has been doing well at 6 months postoperating, showing moderate return of function.
