Operative management of C3-C6 intramedullary gangliocytoma
Bibliographic record
Abstract
Background: Gangliocytoma is a WHO grade 1 tumour which is typically found in the brain. Incidence of this pathology occurring in the spinal cord is rare, accounting for 0.1%-0.4% of intramedullary spinal cord tumors. Methods: We present the case of a previously healthy 23-year-old male with bilateral weakness and accompanying sensory deficits progressing over several months. Magnetic resonance imaging (MRI) of the spine showed a C3-C6 enhancing, intramedullary mass. C3-6 laminoplasty and resection of the tumour was preformed under neurophysiologic monitoring. Post-operatively the patient had no new neurologic deficits. Results: Final histopathology was consistent for gangliocytoma with extensive calcifications as confirmed by two separate neuropathologists. Gross total resection was not possible due to decreased motor evoked potentials detected by electrophysiologic monitoring. Post-operative MRI revealed a residual tumour measuring 58×15×25 mm with no further abnormal foci of enhancement. Conclusions: Gangliocytoma of the cervical cord is exceedingly rare, however its natural history is unclear. In our experience, maximal safe resection is warranted with the goal of preserving neurological status.

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.
