Acute appendicitis of the subhepatic appendix is uncommon, and a preoperative diagnosis is difficult without a thorough understanding of the various anatomical locations. Cross-sectional imaging is indispensable for prompt diagnosis and subsequent treatment. Surgery is the standard treatment for perforated appendicitis in the subhepatic region. In this study, we present a case of subhepatic appendicitis with an unusual presentation.
A 28-year-old man presented to our emergency department with a 3-day history of diffuse right abdominal discomfort, diarrhea, fever, and vomiting. Physical examination revealed rebound soreness and guarding in the right upper and lower quadrants. Laboratory tests revealed high levels of C-reactive protein and serum bilirubin and neutrophilic leukocytosis. Abdominal computed tomography revealed an undescended cecum and a subhepatic appendix with an intraluminal appendicolith, fat stranding, and peri-appendiceal fluid. The patient underwent open exploration and appendicectomy, during which the subhepatic perforated appendix was excised. The patient's recovery was uneventful.
Appendicitis classically presents with right iliac fossa pain.
Anomalous positions of the appendix can give rise to clinical challenges.
Perforation in subhepatic appendicitis masquerades as acute cholecystitis.
Undescended cecum could give rise to the rare anatomical position of the appendix.
