A febrile 9-year-old male complains of nausea and vomiting for the past 3 hours. His 'belly button' started to hurt immediately prior to EMS arrival. He has had a loss of appetite for the past 12 hours. What should you suspect?

Pain that starts around the belly button and then moves to the lower right side, along with fever and vomiting, is classic for appendicitis in a child. The early central (visceral) pain comes from the appendix and is poorly localized; as irritation worsens and the lining of the abdomen becomes inflamed, the pain localizes to the right lower quadrant. Anorexia and fever support an inflammatory/infectious process. In contrast, gastroenteritis typically causes diffuse abdominal cramps with vomiting and often diarrhea, without such a characteristic migratory pattern to the RLQ. Mesenteric ischemia is unlikely in a child and usually presents with severe pain out of proportion to exam in older patients with vascular disease. Pancreatitis in children is uncommon and usually presents with epigastric pain, sometimes radiating to the back, not the migratory RLQ localization. So the presentation most strongly points to appendicitis, and the patient should be transported promptly for surgical assessment.
