AB The differential diagnosis for ulcerating small bowel strictures is extensive and includes exposure to non-steroidal anti-inflammatory drugs (NSAIDs), Crohn’s disease, infections, gastrointestinal lymphoma and vasculopathy. It also encompasses the exceptionally rare and poorly understood diagnosis of cryptogenic multifocal ulcerative stenosing enterocolitis (CMUSE), often a diagnosis of exclusion and considerable difficulty. We present a case of persistent proximal jejunal ulcerating stenoses in a 75-year-old Caucasian man, which continued despite cessation of NSAIDs. After extensive clinical, radiographic, laboratory and ultimately surgical pathological appraisal—as well as failure to improve with both misoprostol and budesonide—he was diagnosed with CMUSE and managed with limited small bowel resection. In the presentation of this case, we aim to underscore the diagnostic challenges that clinicians face in differentiating CMUSE from other more common diagnoses, particularly NSAIDs-induced enteropathy.
