The ultrasound appearances of scrotal oedema

Ultrasound has been shown to be a useful tool in the investigation of both acute and chronic scrotal conditions. We describe the ultrasound appearances of scrotal oedema with different aetiologies. A total of eight patients with scrotal oedema resulting from a variety of conditions, including heart failure, idiopathic lymphoedema, hepatic failure and lymphatic and venous obstruction, underwent ultrasound of the scrotum to determine the appearances common to each case. In all cases, similar appearances of a thickened scrotal wall with an `onion' like appearance surrounding normal testicles was seen. The scrotal wall had a jelly like texture. Awareness of the typical appearances of scrotal oedema on ultrasound and a knowledge of its causes is helpful in distinguishing it from other causes of a swollen scrotum.
