May-Thurner syndrome is a clinical condition that results from narrowing of the left common iliac vein lumen due to pressure from the right common iliac artery as it crosses anterior to it. We describe an atypical case of May-Thurner syndrome in a 23-year-old woman that presented only continuous pain in pudendal zone without vascular symptoms. The Doppler ultrasound, nuclear magnetic resonance and others complementary analyses show the presence of a pelvic venous congestion syndrome and we hypothesized that this condition produced a neuropathic compression of the pudendal nerve in Alcock's canal. Patient was treated with the technique of pudendal nerve blockade by trans-gluteal via. An important reduction in pain of pudendal zone was showed.
