A 61 year-old-man presenting to the emergency department with severe dehydration resulting from intermittent episodes of diarrhoea and profuse mucous discharge from the rectum, found to have villous adenoma. a Sagittal T2-weighted MRI and b axial T2-weighted MRI reveal a carpet-like “hairy” lesion covering the mucosa of the rectum (arrows). The lumen of the rectum is distended and fluid filled (arrowhead) with no proximal obstruction. c Contrast-enhanced MRI reveals enhancement of the thickened abnormal mucosa (arrows)
