The radiological findings on barium enema examination of 239 patients with thyroid deficiency (192 hypothyroid and 47 myxedematous) were reviewed. A new radiologic finding of transverse ridging superimposed on megacolon is described in myxedema and an explanation for this finding is postulated. The colonic findings associated with thyroid deficiency are presented.
