title: [Contribution of sonography to the diagnosis of colonic tumors].
abstract: Though also in future roentgenological and endoscopic bioptic techniques determined the practice in the diagnostics of tumours of the large intestine the routine use of sonography may shorten the way to diagnosis in numerous cases when the so-called cocard phenomenon (= infiltrated intestinal wall) is proved. On the other hand, the cocard phenomenon may serve as an additional criterion of malignity when a roentgenological and/or endoscopic suspicion of malignoma at first cannot be confirmed bioptico-histologically.
