- The case highlights the need for thorough imaging and careful surgical navigation in rare anatomical variants.

## Abstract

Left-sided acute appendicitis (LSAA) is an extremely rare cause of acute abdominal pain, and even the most experienced surgeons may encounter it only a few times in their careers. While acute appendicitis remains the most common indication for emergency gastrointestinal (GI) surgery, its diagnosis is typically straightforward. However, in cases of situs inversus totalis (SIT), the atypical anatomical positioning can obscure the clinical picture and lead to diagnostic uncertainty, often mimicking other left-sided pathologies and potentially resulting in delayed treatment and complications. This case report presents the surgical challenges encountered during an appendicectomy in a patient with SIT, emphasizing the importance of thorough preoperative imaging and meticulous intraoperative navigation. A nine-year-old boy with no prior history of SIT presented with left iliac fossa pain, fever, and vomiting - symptoms consistent with acute appendicitis. Clinical examination and diagnostic workup, including laboratory tests, abdominal ultrasound, and echocardiogram, confirmed an inflamed appendix located in the left lower quadrant with dextrocardia. Given the altered anatomical configuration, a laparoscopic appendicectomy was performed with particular attention to the reversed anatomy. The procedure was completed successfully, and the patient had an uneventful postoperative recovery. Although rare, documenting such cases in detail is essential to enhance clinical awareness and guide effective management. Increasing familiarity with LSAA in SIT can help reduce diagnostic delays and surgical complications while contributing to the broader understanding of rare anatomical variants in surgical practice.
