read this first: abdominal pain in ED

• see as for RIF pain but not appendicitis
• diverticulitis
  • usually age > 50yrs
  • usually left sided pain, tenderness with altered bowel habits, tenesmus, low grade fever
• epiploic appendagitis
  • clinically indistinguishable from diverticulitis or appendicitis depending on which side it is on and accounts for some 7% of cases thought to be diverticulitis
  • mainly chubby women 20-60yrs age
  • a self limiting disease, and thus correct identification on CT prevents unnecessary surgery
  • potential complications that have been reported include adhesions, local abscess formation, intussusception, intraperitoneal loose bodies, bowel obstruction, and peritonitis
  • perhaps 40% of those who do not have surgical excision, have recurrent episodes
