Case Discussion

Ganglion cyst in the obturator canal, compressing on the obturator nerve, resulting in denervation oedema and atrophy of the obturator externus, adductor minimus and brevis muscles.  Obturator neuropathy is relatively uncommon and often seen in the setting of pelvis trauma and surgery. May also be associated with a hernia or sports injury.
