Isolated Visceral Small Artery Fibromuscular Hyperplasia-Induced Ischemic Colitis Mimicking Inflammatory Bowel Disease
Bibliographic record
Abstract
A unique case of fibromuscular hyperplasia (FMH) of the visceral vasculature is presented. A 31-yr-old patient presented with a chronic colitis initially diagnosed as ulcerative colitis 1 yr earlier. On presentation, the endoscopic appearance showed deep linear ulcerations and cobblestoning and was more consistent with Crohn's disease. Biopsies of the area, however, suggested an ischemic etiology. The patient failed to respond to local 5ASA and prednisone therapy and progression of the disease led to a left hemicolectomy. A diagnosis of a small vessel fibromuscular arteriopathy was made on the resected specimen. This is the first case presentation of FMH mimicking inflammatory bowel disease. The lack of any systemic involvement of FMH with isolated small vessel disease has never been reported and serves as an index case of which clinicians should be aware. The literature is reviewed and the possible implications are discussed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
