Imaging findings of perforative appendicitis: a pictorial review.
Appendicitis is common in children. Early diagnosis depends on recognition of characteristic signs and symptoms: right lower quadrant or periumbilical pain, localized tenderness, fever, and leukocytosis. Because these classic features may be difficult to elicit or masked by other complaints, the incidence of perforative appendicitis in children is high. This paper reviews the imaging sequelae with emphasis on CT and sonography findings. Areas of focus include abdominopelvic abscess, peritonitis, pyelephlebitis, pyelethrombosis, and hepatic abscess. Secondary involvement of the urinary and gastrointestinal tracts is also discussed.
