Rectocolonic calcification due to schistosomiasis: A clinicoradiologic study

Four patients who had intravenous pyelography were found to have radiologically visible calcification of the rectocolon and urinary tract due to schistosomiasis. All four patients had mild proctocolitis colonoscopically and multiple calcified schistosomal ova were found in the submucosa histologically. The authors believe that radiologically visible rectocolonic calcification is more common than reported and that it is associated with a clinically mild or latent form of schistosomiasis. © 1984, American Society of Colon and Rectal Surgeons.
