Anaplastic medulloblastoma in a child with Duchenne muscular dystrophy
Bibliographic record
Abstract
A 9-year-old boy with known Duchenne type muscular dystrophy (DMD) presented with signs of increased intracranial pressure. Radiological investigations revealed a lesion in the midline of the posterior fossa. Subtotal resection was performed. Pathology findings were consistent with the diagnosis of anaplastic medulloblastoma. The postoperative lumbar CSF was positive for malignant cells. Postoperatively, the patient showed severe neurological deterioration and lost his capacity to walk. He was treated with craniospinal radiation followed by nonintensive chemotherapy. At 30 months postsurgery, he was still in complete remission but had not recovered his walking ability. This is the second report of a malignant brain tumor in a boy with DMD. The possible link between the 2 conditions is discussed, as are ethical considerations regarding the management of medulloblastoma in children with DMD.

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.
