Giant diverticula or reduplications of the intestinal tract can produce a variety of bizarre radiographic findings. One of two giant diverticula of the colon was demonstrated by barium enema examination in this presented case. These reduplication cysts were apparently the cause of rectal bleeding in a 67-year-old patient.
Duplications are spherical or tubular structures which possess a well-developed smooth-muscle layer and are lined with mucous membrane; they are found at any level from tongue to anus and are usually intimately attached to some portion of the alimentary tube.3 Communication with the intestinal tract is relatively rare.
Giant diverticula of small bowel and colon have been reported.1,3-6 The radiographic studies in these cases showed localized air collections or collections of contrast material in apposition to bowel. In some cases, giant diverticula, instead of being congenital, may be acquired. Differentiation is generally considered to relate to the presence or absence
