A Case Report of Left-Sided Appendicitis due to Midgut Malrotation

Acute appendicitis is the most common cause of abdominal pain that still requires emergency surgery. As a result of delayed diagnosis or misdiagnosis, appendicitis perforation, abscess, generalized peritonitis and sepsis develop, and morbidity and mortality increase. Variations in the location of the appendix in the abdomen are one of the most important causes of false or delayed diagnosis. Left-sided appendicitis due to midgut malrotation is extremely rare in clinical practice and can cause laboratory and radiological findings similar to colonic diverticulitis. Its rarity may lead to a wrong diagnosis. We present a case where intravenous contrast computed tomography was crucial diagnostically and helpful for pre-surgical planning in a patient presenting with an acute abdomen on left-sited perforated appendicitis with midgut malrotation.
