Intraparenchymal chordoid Meningioma After Radiotherapy for Hodgkin Lymphoma: A Case Report and Review of the Literature
Bibliographic record
Abstract
Objective: Hodgkin lymphoma can be treated by radiotherapy or chemotherapy alone or combined. Meningiomas account for 1-4.2% of all primary intracranial tumors in children, and chordoid meningioma is a very rare subtype. In this study, we investigated a case of an intraparenchymal chordoid meningioma that developed during the early stage in a patient with Hodgkin lymphoma who had been treated with radiotherapy. Case: A 10-year-old male patient was diagnosed with Hodgkin lymphoma and was treated with a combination of radiotherapy and chemotherapy. He presented at our emergency service 6 years later. He had a fever and was suffering from discomfort and insignificant left hemiparesis (4/5). Contrast-enhanced cranial magnetic resonance imaging (MRI) showed a mass in the right temporoparietal region. The intracranial lesion was surgically excised. The tumor was identified as a WHO grade 2 chordoid meningioma by the pathological examination. The Ki-67 proliferation index was found to be 20-25%. Conclusion: Surgeons must remember that radiation-associated meningiomas may occur in the early stage of the treatment as well as in the late stage. Young patients with grade 2 chordoid meningiomas must be followed-up in case of recurrence, and tumors with high Ki-67 indexes are highly expected to relapse.

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.
