 A 56-year-old man was admitted to our hospital due to lower right abdominal pain. Blood tests revealed that, inflammation reaction was positive and a cystic mass was pointed out on abdominal CT. We suspected appendiceal mucocele from the CT findings, suggesting the possibility of acute appendicitis with abscess formation and necessitating emergency surgery on hospital day 1. Laparotomy showed the appendix swollen and twisted counter clockwise 720 degrees at the root of the appendix. Laparoscopic appendectomy was performed. The resected appendix was filled with mucin. Pathological findings showed the appendiceal wall had hemorrhage and necrosis, but without malignancy. We diagnosed torsion of the appendiceal mucocele. To our knowledge, torsion of the appendiceal mucocele is rare, with only 12 reports in Japanese literature including our case. It's difficult to diagnose whether the appendiceal cyst is benign or malignant before surgery. We suggested that laparoscopic appendectomy is useful as a total biopsy for diagnosis.
