Presentation
Intermittent rectal bleeding and abdominal pain.
Patient Data
Thickening of the rectosigmoid loops wall and submucosal fat deposition are seen associated with the mural enhancement and water restriction.
Mesenteric vascular congestion of the sigmoid colon associated with multiple reactive lymph nodes within the rectosigmoid mesentery also is seen.
Case Discussion
Endoscopic rectal biopsy: Sections show the non-oriented tangential view of the large intestinal mucosa with marked infiltration of acute and chronic inflammatory cells, composed of lymphocytes, plasma cells and PMNs with characteristic lymphoid aggregation and foci of crypt involvement (cryptitis) without crypt abscess formation. The crypt architecture shows mild variation in size with goblet cells depletion. The epithelial lining of gland also shows mild reactive atypia.
Diagnosis: Chronic active colitis suggestive for IBD (ulcerative colitis).
