Fig. 4. 21-year-old afebrile man with history of gastroesophageal
reflux and dull right lower quadrant pain. He was suspected to have
appendicitis. Contrast-enhanced CT scan shows inflammation of cecum
(curved solid arrow) and terminal ileum (straight solid
arrow) without evidence of appendicitis. Note pericolonic inflammatory
changes (open arrow). CT findings are similar to typhlitis. Patient
had eaten Chinese food before symptoms and Escherichia coli colitis
developed.
