AXR AP (left) shows a non-obstructive bowel gas pattern and a soft tissue mass in the hepatic flexure obscuring the inferior margin of the liver (Currarino sign). AP image from an air enema (above right) shows the soft tissue mass has been reduced from the hepatic flexure to the cecum. AXR AP taken after the air enema (below right) shows disappearance of the soft tissue mass from the cecum and reflux of a large amount of air into the terminal ileum.
