Diagnosing<unk>  could be very difficult because of the condition's many similarities to appendicitis. However, a medical history of ulcers and use of NSAIDs could be an indicator. When patients present with right lower quadrant pain their vitals, such as blood pressure, pulse, oxygen saturation, and temperature, are monitored. A complete blood count (CBC) is done to determine the number of white blood cells present in the patient’s blood and test for leukocytosis, a condition in which the white blood cells are above the normal levels. Abdominal examination usually discloses generalized tenderness, rebound tenderness in the right iliac fossa, guarding, and rigidity. A physical examination that is positive for abdominal pain categorized as McBurney’s point tenderness, Von Blumberg's sign, Rovsing's sign, Dunphy's sign and Psoas sign, could all indicate acute appendicitis and lead to misdiagnosis. However, these physical examination findings are also present in<unk> . In order to diagnose<unk> , a CT or ultrasound may be performed, which would reveal a ruptured peptic ulcer and free fluid surrounding the area of the appendix. Diagnosis through laparoscopy can also be done to distinguish between acute appendicitis and<unk> . Since there has been very few cases of<unk>  recorded to this day, most studies on this condition include observations of the patient from onset to recovery and on site medical decision making.
