In a lateral C-spine radiograph, the sign is caused by a thickened free edge of the epiglottis, which causes it to appear more radiopaque than normal, resembling the distal thumb.
Severe UC can be characterized by various polyps, colonic shortening, loss of haustrae (the small bulging pouches in the colon), and narrowing of the colon.

Fecal calprotectin, a marker of colon inflammation, may be elevated. Computed tomography of the abdomen is not routinely necessary, but may show thickening or inflammation in the distal colon (sigmoid colon) with associated diverticulosis. Treatment may consist of antibiotics, aminosalicylates (mesalamine), or prednisone. In rare cases, surgery ...
