Right-sided Diverticulitis Mimics Appendicitis

BackgroundRight-sided diverticulitis is a rare source of right lower quadrant pain in Western society; however, it is quite common in Asian societies. Right-sided diverticulitis presents very similarly to appendicitis, with right lower quadrant pain, fever, nausea, and laboratory abnormalities, and is often seen in young patients.ObjectivesIn this report, we present a case of right-sided diverticulitis. We review right-sided diverticulitis’ diagnosis and management. It is important to diagnose right-sided diverticulitis because it is a good mimic of appendicitis and ideally should be diagnosed before a patient has unnecessary surgery.Case ReportA 26-year-old Asian woman presented for evaluation of right lower quadrant pain and fever. She was initially thought to have appendicitis clinically, but had right-sided diverticulitis diagnosed by computed tomography (CT) scan. She was admitted and received intravenous antibiotics and bowel rest. Her right-sided diverticulitis resolved in 3 days.ConclusionsSevere right lower quadrant pain in young patients of Asian descent can be right-sided diverticulitis. Right-sided diverticulitis is a benign condition managed medically that mimics appendicitis. CT imaging seems to be the best way to avoid unnecessary surgery.
