An Incidentally Found True Portal Vein Aneurysm Secondary to Left Liver Lobe Aplasia in a Non-Cirrhotic Pregnant Woman Presented With Ovarian Torsion
Bibliographic record
Abstract
We report a rare case of coexistence of true portal vein aneurysm (PVA) with left liver lobe aplasia in a non-cirrhotic pregnant woman presented with ovarian torsion. We discussed the clinical and radiologic findings of a true PVA with left liver lobe aplasia found incidentally in a 27-week pregnant woman presented with acute abdomen and operated for a right side ovarian torsion. Portal vein diameter measured over 20 mm is called as PVA. PVA is an uncommon entity, and most of these aneurysms are acquired and detected in patients with underlying hepatocellular disease and portal hypertension. To the best of our knowledge, there is no report about PVA development secondary to left liver lobe aplasia in English literature. We found this association incidentally in a pregnant woman with normal hepatic parenchyma and no findings of portal hypertension.

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.
