Congenital pelvic arteriovenous malfo rmation are rare lesions, especially in males. Diagnosis was establish ed by arteriography and contrast-enhanced computed tomography scan. Su rgical resection of the AVM relieved our patient of all symptoms. Howe ver, endovascular therapy, either as primary treatment or followed by conventional surgery is the treatment of choice.
