[Congenital giant diverticulum of the descending colon (author's transl)].

At the autopsy of an 80 years old women an about 60 cm long vermiform deverticulum of the colon was detected originating immediately distal from the left colic flexure and running retroperitoneally downnard versus the promontorium. On the basis of topography, histology and length this structure was interpreted as a congenital traction deverticulum.
