Summary

Aphthous ulceration in the colon is typically linked to Crohn's disease. This case report details the first instance of aphthous ulceration identified in pseudomembranous colitis using barium examination.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Diagnostic Imaging

Background:

  • Aphthous ulceration of the colon is a recognized finding in various forms of colitis.
  • Crohn's disease is the most common etiology associated with colonic aphthous ulcerations.
  • Previous literature has not documented aphthous ulceration in the context of pseudomembranous colitis.

Observation:

  • A patient diagnosed with pseudomembranous colitis presented with distinct aphthous ulcerations.
  • These ulcerations were visualized and confirmed through barium examination of the colon.
  • This finding represents a novel association between pseudomembranous colitis and aphthous ulceration.

Findings:

  • The barium examination successfully demonstrated aphthous ulcerations in a patient with pseudomembranous colitis.

  • This case expands the known spectrum of colonic ulceration presentations.
  • The diagnostic utility of barium studies in identifying subtle mucosal lesions is highlighted.

    • Implications:

    • This report suggests that pseudomembranous colitis should be considered in the differential diagnosis of colonic aphthous ulceration.
    • Further research may be warranted to understand the underlying mechanisms linking Clostridium difficile infection and aphthous ulcer formation.
    • Clinicians should be aware of this potential association when interpreting imaging studies in patients with pseudomembranous colitis.
