Partial segmental thrombosis of the corpus cavernosum presenting to the ED

Bedside ultrasonography of the dorsal penis, obtained by the emergency physician (EP), revealed an abnormally enlarged and edematous proximal left corpus cavernosum (CC) compared with the right, extending proximally into the pelvis (Fig. 1). Serum testing for hypercoagulable disorder including international normalized ratio, prothrombin time, activated partial thromboplastin time, fibrinogen, anticardiolipin antibody, lupus anticoagulant, β-2 glycoprotein, and serum protein electrophoresis, was normal. Partial segmental thrombosis of the corpus cavernosum most typically presents as unilateral, firm, proximal penile or perineal mass and has been associated with erectile dysfunction, penile pain, perineal pain, painful erections, dysuria, and decreased urinary flow [1].
