Case in brief

A 75-year-old female presented with acute right upper quadrant pain and was initially suspected to have colon cancer based on CT findings of a mass-like lesion. Colonoscopy revealed an ulcerofungating mass with significant narrowing, but biopsy results were negative for cancer. A follow-up colonoscopy three days later showed improvement, and biopsy confirmed mass-forming ischemic colitis. The patient was treated conservatively and discharged in stable condition after resolution of symptoms.

Diagnostic / clinical pearl

Short-term follow-up colonoscopy and biopsy can effectively differentiate mass-forming ischemic colitis from colon cancer, preventing unnecessary surgical interventions.
