Giant Appendicolith: A Case Report and Review of the Literature.

Acute appendicitis is one of the most prevalent causes of an acute abdomen. Although the cause of appendicitis is not completely understood, the theory of luminal obstruction is a popular belief, with appendicoliths being a common etiology. While appendicoliths are quite common, giant appendicoliths >2 cm are rare. Although previous reports cite only two or three other occurrences of giant appendicoliths, we found at least 11 reported cases in the literature. We present a young male diagnosed preoperatively on computed tomography to have a large appendiceal mass of 2.2 cm. This case is presented for the rarity of giant appendicoliths along with a review of the literature. © Association of Military Surgeons of the United States 2020. All rights reserved.
