We present the case of a 21 year old patient with an incomplete tear of the tunica albuginea occurred after violent masturbation. The diagnostic assessment was performed first clinically, then with ultrasound and with 3 Tesla MRI. 3 Tesla MRI, owing to its high resolution, allowed to exactly detect the tear location leading to precise preoperative planning. After adequate diagnosis through imaging and proper planning, we were able to perform a selective minimally invasive surgical approach to repair the lesion.
