- Usually presents in children with a recent history of upper respiratory infection.
- Diffuse abdominal pain with tenderness not localized to the right lower quadrant.
- Guarding without rigidity
- Generalized lymphadenopathy is present.
|
- Relative lymphocytosis in WBC differential counts is suggestive.
- Negative ultrasound or CT findings help exclude other diagnoses.

Epidemiology and Demographics
The lifetime risk of appendicitis is 8.6 % for males and 6.7 % for females; however, the risk of undergoing appendectomy is much lower for males than for females (12 vs. 23 %) and it occurs most often between the ages of 10 and 30, with a male:female ratio of approximately 1.4:1.
