Congenital Brain Tumors: Diagnostic Pitfalls and Therapeutic Interventions
Bibliographic record
Abstract
Congenital brain tumors are rare, accounting for 0.5% to 4% of all pediatric brain tumors. A 10-year retrospective study based on autopsy and neurosurgical clinical reports with a diagnosis of congenital/fetal/neonatal brain tumor identified 6 cases. Four cases were diagnosed antenatally by neuroradiology. Clinical outcomes in 5 cases resulted in death; 1 patient with choroid plexus papilloma underwent successful resection of the tumor and is still alive. Tumor pathologies consisted of 2 teratomas, 2 choroid plexus papillomas, 1 gemistocytic astrocytoma, and 1 glioblastoma multiforme. A literature review of all fetal cases specific to the pathologies presented in this series was also performed. Relative to the literature, this series contains a rare case of congenital gemistocytic astrocytoma. This series further sheds light on the diagnostic, histological, prognostic, and therapeutic differences between congenital brain tumors and tumors of the same pathology in older pediatric and adult populations.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
