Clinical and imaging mimickers of acute appendicitis in the pediatric population.

OBJECTIVE: The purpose of this article is to present the imaging appearance of common mimickers of appendicitis in children with right lower quadrant pain.

CONCLUSION: The majority of children who undergo imaging for suspected appendicitis will end up having an alternative diagnosis. These mimickers can be gastrointestinal, genitourinary, or pulmonary. Familiarity with these alternative diagnoses can aid in the challenging task of imaging right lower quadrant pain in the pediatric population.
