Congenital renal arteriovenous malformation: ultrasonic appearance.
We report a case in which a congenital renal arteriovenous fistula was detected using gray scale ultrasonography and arteriographically confirmed. This abnormality should be considered when renal ultrasonography reveals anechoic structures located centrally or peripherally within the kidney in association with an enlarged renal vein.
