Presentation
Abdominal pain, fever, diarrhea.
Patient Data
Wall thickening with submucosal edema, mucosal hyperemia, and surrounding stranding involving the distal ileum through rectum. Mild reactive inflammation of the appendix.
Case Discussion
Typical appearance of infectious colitis involving the ileum and entire colon (through rectum).
There is little justification to broad report "nonspecific colitis/enteritis" due to the long segment involvement and clinical presentation. This appearance would not be expected with ischemia as it involves multiple vascular distributions. Regarding inflammatory colitis (specifically ulcerative colitis), while it can involve both the colon and ileum ("backwash ileitis") the ileal segment is usually a few cm rather than such a long segment as in this case. Additionally, there is no loss of the haustral fold pattern typical of ulcerative colitis (lead pipe colon).
