Enteritis and colitis are common causes of acute abdominal pain. Their differential diagnosis is broad, including infectious, inflammatory and ischemic etiologies, each with different management strategies. The purpose of this exhibit is to review the multidetector computed tomography (MDCT) appearance of common infectious, inflammatory, and ischemic forms of acute enteritis and colitis with emphasis on distinguishing clinical and imaging features.

Infectious enteritis and colitis Risk factors Clinical presentation Causes (bacteria, virus, parasite) Distribution patterns according to cause Bowel and mesenteric findings Inflammatory causes - Crohn’s disease and ulcerative colitis (UC).  Demographics Clinical presentation Differences in distribution Gastrointestinal findings including features unique to each Mesenteric findings Extragastrointestinal manifestations Ischemic enterocolitis Risk factors Clinical presentation CT findings in bowel and mesentery (arterial vs venous compromise, time course) Vascular findings Prognosis
