HEMIMEGACEREBELLUM: A REPORT OF ONE CASE
Bibliographic record
Abstract
Objectives: We report clinical and paraclinical features of a patient with an original unilateral hemispheric malformation of cerebellum. Methods: Clinical features, neuropsychological testing, neuroradiological, electrophysiological, metabolic and genetic investigations were performed. Results: This girl is the only child of non consanguineous French Canadian parents. The first neurological examination was performed when she was 2.5 years old and showed a global psychomotor delay (Denver test; DQ=60%). She started to walk at 23 months. Ataxic gait was then observed. She was dysarthric. At the age of 3.5 years, speech remained immature (phonology, syntax). A non-progressive macrocephaly was noticed. Brain MRI at 2.5 years showed a diffusely prominent left cerebellar hemisphere. EEG, genetic and metabolic studies were normal. Brain MRI of the parents was normal. Conclusion: We reported for the first time to our knowledge, an hemispheric cerebellar dysplasia characterized by an “ hemimegacerebellum ” appearance in brain MRI investigation.

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.
