An Unusual Case of Hepatic Abscess
Bibliographic record
Abstract
A case of recurring primary hepatic actinomycosis is reported. A 50-year-old man presented with fever, weight loss and multiple hepatic masses. A diagnosis was obtained by cytological examination of a biopsy sample taken from the largest hepatic mass, which revealed the presence of Actinomyces species. The patient was treated with penicillin for 12 months and did well. Seven years later, he presented with similar symptoms but with a single large liver mass and a pulmonary infiltrate in the right lower lobe. Liver biopsy showed an inflammatory pseudotumour, and lung biopsy showed the presence of Actinomyces species. Again, the patient was treated with penicillin. Five months later, the patient was doing well, and a follow-up computed tomography scan showed partial regression of the hepatic pseudotumour. This case indicates that hepatic actinomycosis can recur several years after an appropriate treatment and stresses the need for careful follow-up in such patients.

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.
