Abstract
Plexiform schwannoma (PS) is an infrequent variety of benign nerve sheath tumor characterized by multi-nodular (plexiform) architecture and the individual thin capsule. The pre-operative diagnosis of PS is difficult. In this report, we describe a case of PS presented in the cerebellopontine angle (CPA) space. Our case involved a 32-year-old woman with one-month history of worsening verbal vagueness associated with unstable gait. MRI revealed a solid-cystic mass with in the left CPA region. The mass was resected completely, and the diagnosis of PS was confirmed by histopathology. While schwannoma commonly occurs in the head and neck, CPA space PS is rare, and pre-operative pathological diagnosis of PS is difficult. MRI studies of PS revealed distinctive features that we found useful in pre-operative diagnosis.

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 it
