    This study describes a rare case of ischemic colitis that mimicked colon cancer on barium imaging. The condition presented as a distinct narrowing in the colon, highlighting diagnostic challenges.

    Area of Science:

    • Gastroenterology
    • Radiology
    • Pathology

    Background:

    • Ischemic colitis is a condition caused by reduced blood flow to the colon.
    • Differential diagnosis of colonic narrowing is crucial for appropriate patient management.
    • Barium examinations are a common imaging modality for evaluating colonic abnormalities.

    Observation:

    • A patient presented with symptoms suggestive of colonic obstruction.
    • Barium examination revealed a short, circumferential narrowing of the colon.
    • This finding closely resembled the appearance of an annular colon carcinoma.

    Findings:

    • The observed colonic narrowing was ultimately diagnosed as ischemic colitis.
    • The imaging findings mimicked malignancy, posing a diagnostic challenge.

  • This case highlights an unusual presentation of ischemic colitis.

    • Implications:

    • Radiologists and gastroenterologists should consider ischemic colitis in the differential diagnosis of annular colonic lesions.
    • Unusual presentations of ischemic colitis can mimic colonic cancer, necessitating careful evaluation.
    • Accurate diagnosis is essential to avoid unnecessary surgical intervention for benign conditions.
