Final answer:

The thumbprint sign on an x-ray usually indicates ischemic colitis, a condition characterized by the loss of blood flow to the colon, causing inflammation and injury.

Step-by-step explanation:

The phrase "thumbprint on x-ray" often refers to a finding seen in a condition ischemic colitis. Ischemic colitis is a medical condition that occurs when there is a temporary loss of blood flow to the colon, leading to inflammation and injury to the colon. On an abdominal radiograph, ischemic colitis can present with a "thumbprint" sign, which is caused by localized edema in the wall of the intestine.


This is a nonspecific sign but is associated with ischemic colitis and other forms of colonic inflammation or infection such as pseudomembranous colitis. The radiograph findings are not as common as CT findings but can be used in conjunction with a patient's clinical presentation and other diagnostic modalities to reach a diagnosis.
