摘要

Colonic diverticulitis is rare in the pediatric population and often presents with nonspecific symptoms that may be misdiagnosed as other causes of acute abdominal pain, such as appendicitis, leading to diagnostic uncertainty and variability in management. We report a case of pediatric colonic diverticulitis and present a systematic review to characterize its clinical presentation, diagnostic challenges and management. Clinical data for the index patient were retrospectively reviewed, and parental consent was obtained. A structured literature search was performed using PubMed, Scopus, and Embase. Studies reporting patients younger than 18 years were included. A 16-year-old male presented with right lower quadrant pain. CT suggested cecal diverticulitis. Worsening symptoms prompted diagnostic laparoscopy, revealing an inflamed diverticulum adjacent to a normal appendix. The postoperative course was uneventful. The review identified 27 studies including 101 patients. Median age was 14 years (IQR 12–16; range 3–17), with 57% male preponderance. Most cases involved a solitary right-sided diverticulum. CT correctly identified diverticulitis in 85%. Complicated disease occurred in 17%. In conclusion, in the pediatric age diverticulitis often arises from a solitary cecal diverticulum and can closely mimic appendicitis. Awareness may improve diagnosis, and uncomplicated cases can be treated conservatively with careful follow-up and appropriate clinical monitoring.
