Laparoscopic approach was used to confirm the diagnosis and to perform appendectomy. Trocars placement was tailored for this peculiar case. Discussion: One third of patient with acute appendicitis complains abdominal pain in an unexpected location due to various anatomical position of appendix. Left-sided acute appendicitis is a cause of misdiagnosis and it can occur in association with anatomical anomalies such as situs viscerum inversus and midgut malrotation. Laparoscopic surgery may represent a valuable approach in terms of differential diagnosis and treatment in these patients.
