Examination of the pathological scrotum with dynamic and static ultrasound.

Ultrasound examination was performed on 51 patients with clinically pathological scrotum who all underwent surgery. Twenty patients had extratesticular disease and 31 patients had intratesticular disease. The disease was located correctly by ultrasound in all cases. It was, however, not possible to tell a malignant from a benign lesion, or a teratoma from a seminoma. A combination of contact scanning with direct palpation of the lesion and scanning through a water bath or similar "stand-off' arrangement is recommended.
