Tumour Emboli Causing Multifocal Ischemic Stroke from Intracardiac Malignant Solitary Fibrous Tumour
Bibliographic record
Abstract
A 78-year-old woman presented to the emergency department with gait ataxia and diplopia. Her past medical history included the surgical resection of a phyllodes breast tumour 8 years prior, with no known recurrence. A computed tomography (CT) scan of the brain demonstrated multifocal right supratentorial hemispheric subacute infarcts in the frontoparietal, posterior temporal and occipital regions. The patient developed recurrent generalized seizures in hospital. Transesophageal echocardiogram demonstrated a large 2.7 × 1.8 × 0.8 cm mobile echogenic mass attached to the left posterior atrial wall. CT angiogram of the chest revealed the left atrial mass as well as a mass encasing the right bronchus intermedius. The patient opted for comfort care and passed away in hospital. Autopsy revealed the tumour to be a primary cardiac solitary fibrous tumour. We present a case of multifocal ischemic stroke and seizures secondary to tumour emboli originating from intracardiac solitary fibrous tumour.

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.
