Abstract:
Arteriovenous malformations (AVM) are most commonly found in the gastrointestinal tract, and presentation can range from asymptomatic to massive gastrointestinal hemorrhage. This case highlights a unique presentation of AVMs. During a screening colonoscopy, a 5-cm mass was discovered in the transverse colon encompassing 25% to 50% of the circumference of the lumen. Biopsies showed polypoid AVM with overlying inflammatory polyps without evidence of malignancy or dysplasia. There are many treatment options for AVM removal. In this case, since suspicion for malignancy was high, the patient underwent surgery and will be closely monitored.
