Polycythaemia Vera Presenting As A Porta Hepatis Mass.
Bibliographic record
Abstract
Polycythaemia Vera (PV) is a myeloproliferative disorder in which bone marrow has increased production of red blood cells, white blood cells and platelets. The hallmarks of the disease are veno-occlusive events, secondary to increased blood viscosity. Polycythaemia Vera rarely presents with portal vein thrombosis below age of 55 years especially in absence of any chronic liver disease. We report a case of 30-years-old South Asian male presenting with abdominal pain, weight loss and vomiting for 3 months. On evaluation, he was found to have oesophageal varices. Furthermore, CT scan showed infiltration at porta-hepatis and portal venous thrombosis. Polycythaemia Vera was diagnosed with a positive JAK2 mutation and increased haemoglobin. Laparoscopy was done to perform biopsy of the porta-hepatis mass. Biopsy showed engorged vessels with no sign of malignancy. Patient underwent repeated sessions of upper GI endoscopy for band ligation and multiple sessions of venous phlebotomy which drastically improved his blood indices. He was started on lifelong aspirin and was advised regular follow-ups. With early recognition and prompt management patients can be prevented from potential complications which can prove to be detrimental.

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.
