Which of the following findings is most likely to be present on colonoscopy of this patient?? A: Pseudomembranes overlying regions of colonic inflammation, B: Patchy inflammation of mucosa with cobblestone appearance and intervening areas of normal mucosa, C: Confluent inflammation of the colonic mucosa with edema, fibrin-covered ulcers, and loss of vascular pattern, D: Normal colonic mucosa, E: Numerous polyps extending throughout the colon,  <response>: This is a clinical vignette describing a 22-year-old woman with a 6-month history of lower abdominal pain, bloody diarrhea, weight loss, and a family history of colon cancer. She has physical exam findings consistent with left lower quadrant tenderness concerning for colitis. Lab studies show anemia, leukocytosis, and positive p-ANCA concerning for inflammatory bowel disease. A colonoscopy is planned to evaluate for colitis. The key findings pointing towards ulcerative colitis are the young age, chronic bloody diarrhea, weight loss, abdominal tenderness, anemia, and positive p-ANCA. Given the chronicity and systemic symptoms, this is likely moderate-severe colitis. The most likely colonoscopic finding in ulcerative colitis is confluent colonic inflammation with ulcers and loss of vascular pattern.Pseudomembranes are seen in C. difficile colitis. Cobblestoning and patchy inflammation is more characteristic of Crohns disease. Normal mucosa and polyps would not correlate with her symptoms.C: Confluent inflammation of the colonic mucosa with edema, fibrin-covered ulcers, and loss of vascular pattern
