Retroperitoneal Actinomycosis Mimicking a Malignant Neoplasm of Adrenal Gland
Bibliographic record
Abstract
Actinomycosis is a chronic disease characterized by abscess formation, tissue fibrosis, and draining sinuses. In this study, we aimed to present the clinical and radiological findings of a rare pathology, retroperitoneal actinomycosis case mimicking adrenal tumor and review the literature. Physicians must be aware of typical clinical presentations (such as cervicofacial actinomycosis following dental focus of infection, pelvic actinomycosis in women with an intrauterine device, and pulmonary actinomycosis in smokers with poor dental hygiene), but also that actinomycosis may mimic the malignancy process in various anatomical sites. Actinomycosis manifests as tumor-like lesions mainly in the cranio-cervical region (60-80%), thorax (10-15%), abdomen (5-20%) and exceptionally in retroperitoneal organs. Positron emission tomography (PET) revealed hypermetabolic mass lesion 63 × 52 × 73 mm in size on the left adrenal gland showed a standardized uptake value (SUV) of 18.2. The patient underwent left adrenalectomy. The pathologic examination revealed actinomycosis. The patient was treated with antibiotics.

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.
