A case of metastatic adenocarcinoma of the prostate arising in a meningioma
Bibliographic record
Abstract
We present the case of a 70-year-old man who had a prostate adenocarcinomathat metastatized to a previously unknown cranialmeningioma. Central nervous system (CNS) metastases are veryuncommon in patients with prostate cancer, and metastases topre-existing primary CNS tumours are even more uncommon. Rareevents like this can cause diagnostic uncertainty, as shown by thiscase. This case is a reminder for clinicians to consider prostatemetastases in patients with known prostate carcinoma and focalneurological symptoms.Nous décrivons le cas d'un homme de 70 ans présentant un adénocarcinomemétastatique de la prostate secondaire à un méningiomeintra-crânien non diagnostiqué auparavant. Les métastasesau niveau du SNC sont très rares chez les patients atteints de cancerde la prostate et les métastases sont encore plus rares dansle cas de tumeurs primitives pré-existantes au niveau du SNC.La rareté de ces cas peut soulever des incertitudes au niveau dudiagnostic, comme nous le montrerons. Ce cas permet de rappeleraux cliniciens d'envisager la possibilité de métastases chezles patients atteints d'un carcinome prostatique confirmé et présentantdes signes neurologiques focaux.

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.
