Intramuscular Myxoma of the Paraspinal Musculature
Bibliographic record
Abstract
Intramuscular myxomas are uncommon, benign tumors of mesenchymal origin most noted for their occurrence in the left atrium. We present a rare case of intramuscular myxoma involving the paraspinal muscles of an 80-year-old woman, presenting with longstanding lower back pain. There was no focal neurological deficit. Imaging revealed a large lobulated paraspinal mass, with heterogeneous rim enhancement, causing adjacent bony changes and intraspinal extension. Open spinal biopsy with debridement and drainage of a suspected paraspinal abscess was done. The diagnosis of an intramuscular myxoma was however confirmed on histopathology. Intramuscular myxomas, particularly those occurring in distinctly uncommon locations, with aggressive features, can pose diagnostic challenges and should be included in the differential diagnosis of all paraspinal cystic lesions. doi:10.4021/jmc37w

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.
