A rare case of acute abdomen: acute appendicitis in a patient with midgut malrotation

Acute appendicitis (AA) is the most common pathology requiring surgery in patients presenting to the emergency department with abdominal pain. AA is usually suspected and diagnosed with abdominal pain localized to the right lower quadrant based on anamnesis and physical examination findings. Atypical anatomical localizations of the appendix vermiformis often do not give typical anamnesis and examination findings and cause delays in diagnosis and treatment. In the presence of Midgut Malrotation (MM) and Situs Inversus Totalis (SIT), the appendix is localized in the left lower quadrant due to malrotation. In this article, we report a case of midgut non-rotation that presented with left lower quadrant pain and was diagnosed with acute appendicitis.
