Q

6 year old with periumbilical pain yesterday, now presents with RUQ tenderness and guarding, but no rebound tenderness…best diagnostic test to determine if surgery is necessary?

CT with contrast, because best way to rule out appendicitis is via CT with contrast

-Don’t be tricked into steering way from thinking appy just because there is no rebound tenderness and going after ruling out something like Yersinia, mesenteric adenitis, or Crohn’s
