The hamburger sign is used in the diagnosis of appendicitis.[1] The sign is used to rule out that disease, with the physician inquiring if the patient would like to consume their favourite food.[2] If a patient wants to eat, consider a diagnosis other than appendicitis. Anorexia is 80% sensitive for appendicitis.[1] A positive hamburger sign is demonstrated by a patient declining food.[2]
