Superselective angioembolization in posttraumatic pseudoaneurysm of corpora cavernosa presenting as acute urinary retention.

Pseudoaneurysm of corpora cavernosa is rare and its presentation as acute urinary retention has not been reported in the literature so far. We report a 47-year-old gentleman who presented with acute urinary retention. Doppler ultrasound revealed pseudoaneurysm of corpora cavernosa at bulbar urethra region with 2 feeder vessels with turbulent flow inside. Selective internal pudendal artery angiogram was done and two feeder arteries from bilateral pudendal arteries were confirmed. Trans perineal thrombin & fibrinogen instillation and selective coil embolization of left internal pudendal artery were done, leading to complete obliteration of pseudoaneurysm and alleviation of patient's symptoms.
