Diverticulosis of the appendix with diverticulitis: case report.
Diverticulum of the appendix is rarely encountered. A case of appendiceal diverticulosis is described. A 46-year-old male patient was sent to our hospital with presentation of acute appendicitis-like symptoms. The appendix was removed by laparoscopic appendectomy, and it showed erythematous change with local peritoneal reaction and omental shift at the tip. Pathological examination revealed three diverticula in the appendix. One of them was inflamed but the appendix itself was not. All three diverticula were pseudodiverticula, lacking muscularis propria. The appendix in this case showed only focal inflammatory change, which differs from what occurs in acute appendicitis, where diffuse inflammation of the appendix is usually noted. In cases of an appendix with only focal erythematous change, minor lesions such as diverticulitis may be revealed by pathological examination, and an appendectomy is still warranted. Diverticulitis of the appendix cannot be differentiated from acute appendicitis preoperatively. Image studies including abdominal computed tomography scan, ultrasonography, and plain film cannot improve the diagnosis. To our knowledge, diverticulosis of the appendix has never been reported in Taiwan.
