Roentgenologic studies obtained in 58 children with the severe form of kwashiorkor and 19 with the mild form, or at the beginning of clinical manifestations revealed that plain roentgenograms of the abdomen often demonstrate the presence of fluid levels in the small intestine. The principal roentgenologic signs of this disease are based on disturbances of motor function. The roentgenologic picture varies from case to case and depends on the severity and duration of the disease. The whole alimentary tract may be affected in the severe cases. Despite clinical improvement and even cure, the roentgenologic abnormalities may persist for a long period of time.
