MSFinals-1324
A 20-year-old male has been referred by his doctor due to experiencing severe bloody diarrhoea on and off for the past three months. After undergoing a barium enema, it was discovered that he has multiple ulcers and signs of inflammation that extend from his rectum to the mid transverse colon. A colonoscopy was performed and biopsies were taken from various sites, revealing acute and chronic inflammation that is limited to the mucosa. What is the most probable diagnosis for this patient?
