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 his/her 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]
