Abstract
Abstract Cases of the Month, April–June, 2001 The April Case of the Month (COM). The contributors report a case of a 70 year‐old woman with recurrent meningiomas, one of which showed rhabdoid and lipomatous differentiation. Histopathological study of the first and second previous resections showed only typical meningothelial meningioma. On the third craniotomy, a new tumor specimen showed an admixture of classic meningothelial meningioma with lipomatous and rhabdoid foci. Immunohisto‐chemical studies showed diffuse reactivity for epithelial membrane antigen and vimentin, as well as focal positivity for desmin and smooth muscle actin in the areas with rhabdoid features and S100 protein in the lipomatous foci. The presence of these three different and concomitant histological patterns only in the third surgical resection might support a meta‐plastic origin and, also, corroborates the concept that rhabdoid features are suggestive of an aggressive behavior. The May COM. A 32‐year‐old woman with a history of previous mastoid surgery presented with bilateral extremity weakness and ambulatory instability. MRI revealed a dural‐based mass completely encircling the upper cervical spinal cord. Workup was significant for an abnormally elevated c‐ANCA, positive at a dilution Of 1:128. A portion of the lesion was removed by a posterior surgical approach to decompress the cervical cord. Histologic examination of the dura showed a dense granulomatous infiltrate with vasculitis and giant cells; coupled with the positive c‐ANCA, the Process was felt to be most consistent with Wegener's granulomatosis. Wegener's granulomatosis infrequently involves the dura or meninges and has not previously been reported to affect dura of the cervical cord. Symptomatic improvement followed surgical decompression and high‐dose corticosteroid therapy, with resultant resolution of an elevated c‐ANCA titer. The June COM. A 61 year old female presents with a three week history of increasing confusion, lethargy and headache. A neurological exam revealed dis‐orientation, mild expressive aphasia, bilateral papilledema, and a right pronator drift. She had a craniotomy and resection of tumor. The tumor histologically was consistent with a solitary fibrous tumor displaying malignant features of hypercellularity, marked nuclear atypia, high mitotic activity, and a high proliferation index. This case is unique as the first malignant variant of solitary fibrous tumor to be reported intracranially.

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
