A Potentially Hazardous Superficial Ulnar Artery, Supernumerary Lung Fissures, Undescended Caecum and Many More– A Cadaveric Case Report of Multiple Anomalies

Introduction: Anatomical anomalies, though often isolated, can occasionally present as multiple deviations within a single individual, offering valuable insight into the complexity and diversity of human anatomy. Case report: This cadaveric case report details a rare combination of anatomical variations observed during routine dissection at a tertiary care medical college in Chennai in 2025. A 68-year-old male cadaver was found to have four distinct anomalies: a superficial ulnar artery (SUA) arising from the axillary artery; a supernumerary fissure in the right lung creating a fourth lobe; an undescended caecum and appendix located in the subhepatic region; and bilateral absence of the plantaris muscle. The superficial ulnar artery followed an unusual superficial course, increasing the risk of iatrogenic injury during procedures such as venipuncture or intravenous cannulation. The supernumerary fissure, categorized under Craig & Walker Type II classification, divided the inferior lobe of the right lung, a variation that may complicate pulmonary surgery. The subhepatic positioning of the caecum and appendix, while often asymptomatic, could mimic hepatobiliary pathology and present diagnostic challenges in cases of acute appendicitis. Conclusion: This report contributes to the growing body of literature on anatomical variations by documenting a unique confluence of multiple anomalies not previously reported together. Recognition and understanding of these variations are crucial in preoperative planning, imaging interpretation, and surgical safety.
