Sigmoid Diverticulitis in an Obese Pediatric Patient Without Genetic Predisposition

Sigmoid diverticulitis has historically been a rare cause of abdominal pain in pediatrics, with minimal cases documented in the literature. The patient studied is one of the first reported cases of acquired pediatric uncomplicated sigmoid diverticulitis in whom lifestyle was the main contributing factor, as all associated known genetic risk factors were absent. Given the rarity of the diagnosis, many pediatricians may not consider the diagnosis; however, with the increasing incidence in younger patients, consideration of diverticulitis on the differential diagnosis with lower abdominal pain, especially in patients predisposed to diverticular disease, is increasingly important to avoid misdiagnosis and potential delays in appropriate treatment.
