Idiopathic Hypertrophic Pachymeningitis as a Rare Cause of Spinal Cord Compression
Bibliographic record
Abstract
Hypertrophic pachymeningitis is a chronic diffuse inflammatory fibrosis of dural mater. We herein report a rare case of spinal cord compression caused by idiopathic spinal hypertrophic pachymeningitis. A 49-year-old man, with a history of HIV infection, presented with worsening thoracic back pain and right leg pain for one year. A continuous epidural mass from T1 to T4 and a second ventral epidural mass at L5 were found on the MRI scan of the spine. Laminectomy and spinal cord decompression were performed, and the histopathology reported fibrosis with mixed inflammatory cellular infiltrates in the dural mater without any evidence of mycobacterial and fungal infection. The diagnosis of idiopathic spinal hypertrophic pachymeningitis was concluded. He received steroids therapy and recovered full neurological functions. The existing English literature on this rare disease was reviewed and discussed. doi:10.4021/jmc637w

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.
