Successful treatment of anaplastic meningioma metastatic to cervical lymph nodes
Bibliographic record
Abstract
BACKGROUND: Cervical lymph node metastases of meningioma represent an important diagnostic and treatment challenge. Not only has this entity been rarely described, but successful treatment has never been reported in the literature. METHODS AND RESULTS: This case report was conducted using reviews of the literature. A 58-year-old man with a history of resected anaplastic meningioma was referred for a right neck mass. Excisional biopsy revealed metastatic meningioma, and a metastatic workup was negative. Modified radical neck dissection showed positivity in 5 lymph nodes. The patient received adjuvant intensity-modulated radiation therapy (IMRT), for a mean target dose of 60 Gray (Gy). Two years after treatment, the patient was disease free. Eleven cases of cervical lymph node metastasis of meningioma were identified in our literature search, and none described successful treatment of this entity. CONCLUSION: Cervical lymph node metastasis of anaplastic meningioma is potentially treatable with surgical resection and IMRT, although further studies with long-term follow-up are necessary.

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.
