title: Primary ultrasonic detection of a double carcinoma of the colon.
abstract: Abdominal sonic scanning revealed two irregular, circular masses with light central reflexes followed by an acoustic shadowing effect. The diagnosis of two colonic tumors was subsequently confirmed by barium enema examination and surgery. Ultrasonic examination is capable of detecting colonic tumors above a certain unspecified size.
