Spinal Atypical Teratoid Rhabdoid Tumor in a 14-Year-old Child With Down Syndrome: A Case Report
Bibliographic record
Abstract
Individuals with 21 trisomy or Down syndrome (DS) are known to have an increased risk of acute leukemia, while they rarely develop solid or central nervous system (CNS) tumors. Atypical teratoid rhabdoid tumor (ATRT) is a highly aggressive CNS-WHO grade 4 neoplasm, which has never been reported in association with Down syndrome. We present a case study of a 14-year-old female with Down syndrome, diagnosed with intradural-extramedullary spinal ATRT. The chief complaints included bilateral lower limb weakness, constipation, and urinary incontinence for 2 weeks. Surgery was scheduled, and a biopsy was taken. The histopathology, immunohistochemistry, and molecular analysis confirmed the diagnosis of the ATRT-MYC/group 2B subgroup. This report highlights the challenges of managing a patient with complex medical conditions. Moreover, it adds to the existing literature on CNS tumors in patients with Down syndrome.

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.
