Question: A 28-year-old woman with cystic fibrosis, mild lung disease, and exocrine pancreatic insufficiency, without previous surgery, consulted for a 2-week history of right lower quadrant abdominal pain. The patient denied associated symptoms such as fever, diarrhea, or constipation. Physical examination revealed a painful palpable mass at the right lower abdominal quadrant. Blood tests, including C-reactive protein, were within normal limits and fecal calprotectin was high (234 μg/g feces; normal, <50 μg/g feces).
