Type B2 Appendiceal Duplication with Appendicitis: A Case Report

摘要

Although rare, anomalies of the appendix do occur and may have serious clinical and medicolegal implications. Fewer than 100 cases have been reported in the literature 1, 2. Collins found only 2 in 50,000 appendices, or 0.004 percent 3. This is a case of cecal appendiceal duplication with both appendices showing inflammation on pathologic exam. Case Report A twelve-year-old male presented to the emergency room with a 36-hour history of periumbilical and right lower quadrant (RLQ) abdominal pain and anorexia. The patient's white blood count (WBC) and differential were within normal limits and his abdominal films were unremarkable. The physical exam was significant for guarding and rebound tenderness in the RLQ. The patient was taken to the operating room for diagnostic laparoscopy and laparoscopic appendectomy. At that time, two cecal appendices were noted (Figure 1, Figure 2), both of which showed signs of inflammation without evidence of perforation or abscess. Laparoscopic appendectomies were performed without difficulty. The patient did well postoperatively and was discharged home the following morning. The final pathology report revealed acute appendicitis for both appendices.
