A thirteen-year old girl presented with acute right lower quadrant abdominal pain for which evaluation suggested appendicitis. At laparotomy, the appendix was normal but a Meckel's diverticulum with an impacted Taenia saginata (tapeworm) was found. The diverticulum was excised and histopathology confirmed diverticulitis from the parasite. Though Meckel's diverticulitis due to parasites has been reported, this is usually from ascaris. Tapeworm causing this complication is rare.
