[Traumatic rupture of the diaphragm - a problem of radiological diagnosis (author's transl)].

Traumatic ruptures of the diaphragm are frequently missed, resulting in a delayed diagnosis. Six patients with this entity are presented and the literature is reviewed. Several radiological findings which are easily overlooked, are described. The so-called pseudodiaphragm effect, due to herniated bowel or stomach and mimicking an elevated diaphragmatic leaflet, is emphasized.
