Our patient suffered a perineal straddle injury, resulting in right cavernosal artery pseudoaneurysm in combination with a cavernosal-urethral fistula. The urethra failed to heal after several weeks, and the patient presented with severe intermittent urethral bleeding. The pseudoaneurysm was successfully treated by coil embolization, with resolution of the bleeding. The patient recovered completely, with normal erectile and voiding function. This type of injury is very rare in the literature: traumatic cavernosal arterial pseudoaneurysm is known to cause high flow priapism, but in this case additional cavernosal-urethral fistula resulted in a severe urethraggia. This is the only case, to our knowledge, of delayed urethral bleeding from cavernosal artery pseudoaneursym in combination with a cavernosal-urethral fistula.
