Abstract

fetched live from OpenAlex

Mucinous Cystic Neoplasms (MCNs) of the pancreas are rare, typically affecting women and carrying potential for malignant transformation. While complications like fistulas between MCNs and adjacent structures are rarely reported, this case presents the first documented fistula between a pancreatic MCN and the portal venous system. A 56-year-old woman with acute abdominal pain was found to have a 10.4 cm cystic mass in the pancreatic tail, consistent with an MCN. The lesion exhibited high-risk features. During her admission, a progressive venous filling defect, presumed to be a thrombus, developed despite anticoagulation therapy. Percutaneous thrombectomy revealed a communication between the splenic vein and the cystic mass, with mucinous content aspirated, confirming a fistula with direct extension of mucin into the vein. Distal pancreatectomy confirmed the diagnosis of an MCN with high-grade dysplasia and ovarian-like stroma. This case highlights the rare occurrence of a fistula between a pancreatic MCN and the portal venous system, underscoring the importance of early recognition for proper treatment and surgical planning.

Teacher imitation

Not 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.
