ABSTRACT

Introduction: it’s suggested to use Nantes criteria, image and neurophysiology studies to rule out differential diagnoses. Clinical case: 25-year-old female, lumbar pain, radiating to right gluteal and dyspareunia. Three of the five Nantes criteria were integrated and no response to conservative treatment. Electromyography reports demyelinating sensory neuropathy of the right pudendal nerve. An analgesic block of the pudendal nerve guided by tomography was made. Results: follow-up after two and four months showed 90% improvement, decreased pain, no dyspareunia, VAS 2 of 10 and ODI 10%. Conclusions: diagnostic suspicion is crucial for the timely management of pudendal nerve neuralgia.
