A 62-year-old man with suspected pudendal neuralgia was admitted to a department of clinical neurophysiology for examination. The patient had experienced increasingly altered sensations in the groin, particularly in form of pain in a sitting position. The neurophysiological studies substantiated the suspicion. Pudendal neuralgia is a painful neuropathic condition. The most frequent cause is entrapment of the pudendal nerve in the pelvis. The diagnosis is made clinically by using Nantes criteria, and neurophysiological studies of the perineum are important supplements when pudendal nerve entrapment is suspected.
