A 9-year-old child presents with fever and abdominal pain around the umbilicus that localizes to the right lower quadrant; what is the most likely diagnosis?

The main idea being tested is how pain from abdominal inflammation presents in children. When the appendix becomes inflamed, the initial pain is often felt around the umbilicus because the midgut’s visceral nerves refer pain there. As the inflammatory process worsens, the pain typically shifts and localizes to the right lower quadrant, often with fever. This migratory pattern is a classic clue for appendicitis in a child. In this scenario, a 9-year-old with fever and abdominal pain that starts near the umbilicus and moves to the right lower quadrant fits this pattern well. Other conditions don’t usually show the same migratory course: gastroenteritis tends to produce diffuse pain with vomiting and diarrhea; a urinary tract infection commonly presents with dysuria and urinary symptoms rather than localized RLQ pain; Meckel’s diverticulum can mimic appendicitis but is more often associated with painless bleeding or less typical fever and localization.
