Acute abdominal pain is the second leading cause for an emergency room visit after chest pain in adults. A vast proportion of this is for right lower quadrant pain and CT is the modality of choice for evaluating this. Although appendicitis is the most common clinical concern there are several other diseases that involve the ileocecal area and present with RLQ pain. In this exhibit we will review the key CT features of inflammatory conditions (inflammatory bowel disease, appendicitis, epiploic appendagitis, typhlitis, mesenteric adenitis), Infections (TB, amebiasis), neoplasms ( adenocarcinoma, lymphoma, carcinoid) and other conditions including ischemia, cecal volvulus and intussusception which involve the ileocecal area. Emphasis will be on key features that help diagnose or narrow the differential diagnosis along with clinical history and lab work.

Overview Review the normal anatomy of the ileocecal area  Factors to evaluate i.e bowel wall thickening, mesenteric stranding, lymphadenopathy, sinus/fistulous tracts, abscess, pneumatosis coli, free air  Key features of common infectious, inflammatory, neoplastic and other miscellaneous conditions affecting the ileocecal area  Summary
