Portal Vein Thrombosis and Cavernoma Formation in a Patient With Small Vessel Vasculitis
Bibliographic record
Abstract
Caput medusa or palm tree sign refers to dilated tortuous paraumbilical veins acting as portosystemic shunt in patients with portal vein thrombosis (PVT). We present an asymptomatic male patient who was diagnosed to have chronic PVT with cavernoma formation. His initial presentation was acute exacerbation of chronic obstructive lung disease. He was known to have small vessel vasculitis resulting in ischemic bowel resection. Bowel ischemia and surgical intervention are predisposing factors of PVT which is underdiagnosed clinically and when diagnosed, is diagnosed with delay. Early diagnosis has a good prognosis and can potentially avert morbidity. J Med Cases. 2015;6(10):447-449 doi: http://dx.doi.org/10.14740/jmc2272w

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
