A classic sign of appendicitis in children is which symptom?

• A. Peri-umbilical pain migrating to the right lower quadrant with fever and guarding
• B. Left lower quadrant pain
• C. Nausea only
• D. Headache and photophobia

Answer: (A)

In children with appendicitis, the hallmark pattern is visceral pain that begins around the umbilicus and then migrates to the right lower quadrant as the inflammation localizes to the appendix. This migration happens because initial visceral pain is poorly localized, and once the peritoneum over the appendix becomes irritated, the pain becomes sharply focused in the lower right abdomen. Fever and guarding reflect the inflammatory response and peritoneal irritation, making these together a classic presentation. Left lower quadrant pain isn’t typical for appendicitis and suggests other conditions; pain described as nausea alone is non-specific, and headaches with photophobia point to neurologic or migraine causes rather than abdominal inflammation.
