Penile fracture due to "rolling over in bed injury".

Traumatic rupture of the corpus cavernosum is an infrequently reported condition. The injury involves rupture of tunica albuginea of one or both corpora with or without rupture of urethra resulting from injury incurred to an erect penis. This commonly results from forcible manual deflection of an erect penis, forceful attempt at vaginal penetration and hitting perineum, fall onto erect penis, sexual maneuvers etc. “Rolling over in bed” is a very rare etiology. Characteristically, a cracking sound is heard with sudden pain followed by detumescence, swelling and discolouration.
