title: Ultrasonic diagnosis of hypernephroma extending into the inferior vena cava.
abstract: Extension of hypernephroma into the inferior vena cava was demonstrated by ultrasound. When a solid renal lesion is encountered, it is suggested that the inferior vena cava be scanned. The possible significance of gray scale scanning as a more precise diagnostic tool and its use in tumor staging are discussed.
