Unusual Presentation of a Dysembryoplastic Neuroepithelial Tumor Mimicking a Pontomesencephalic Cavernous Hemangioma
Bibliographic record
Abstract
Dysembryoplastic neuroepithelial tumor is a rare benign neoplasm that usually occurs in children and young adults and is characterized by intractable seizures that are refractory to medication. Since its description and inclusion in the World Health Organization classification of brain tumors, an increasing number of cases have been reported. The tumor is preferentially, but not exclusively, located in the supratentorial cortex. Rare cases of other locations have been reported. We describe the clinical, imaging and pathologic features of a case of dysembryoplastic neuroepithelial tumor arising in the pons of a 26-year-old woman, an unusual extracortical location, mimicking a cavernous hemangioma. doi: http://dx.doi.org/10.4021/jmc718w

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.
