Intraneural ganglion cyst - peroneal nerve

Case contributed by Dr Maulik S Patel


Foot drop - 2 mths. NCV - Common peroneal nerve level pathology. Referred for nerve tracing to check anatomy / pathology

Patient Data

Age: 40 yrs
Gender: Male

Peripheral nerve tracing was done from distal thigh to ankle.

  • Common peroneal nerve: hypoechoic / anechoic and thickened in its entire length
  • Articular branch: hypoechoic / anechoic and thickened in entire visualized segment
  • Superficial and deep branches: normal
  • A cutaneous branch from common peroneal nerve: lateral sural cutaneous nerve
    • hypoechoic / anechoic and thickened
  • Distal sciatic nerve, tibial nerve: normal

Case Discussion

Findings suggest an extension of intraneural ganglion cyst from proximal tibio-fibular joint to articular branch of common peroneal nerve, ascent to to common peroneal nerve and descent to a cutaneous branch from common peroneal nerve (possibly lateral sural cutaneous nerve).

No surgical follow up.
