Superficial Siderosis as a Manifestation of a Dural Arteriovenous Fistula
Bibliographic record
Abstract
Dural arteriovenous malformations (DAVF) represent 10-15% of cerebral vascular malformations 1 .When symptomatic, their manifestations are directly related to the DAVF's location and its pattern of venous drainage.Neurological symptoms may present acutely or progressively, however intracranial hemorrhages occur spontaneously.No case of repeated intermittent hemorrhage due to an intracranial DAVF has been reported.Continuous or recurrent microhemorrhages into subarachnoid spaces are the proposed pathogenesis of superficial siderosis (SS), an uncommon and often unrecognized condition 2- 6 .Resultant hemosiderin deposits in the leptomeninges, pial and subpial layers progressively induce neuronal damage and are responsible for SS manifestations 2 .Although other vascular pathologies have been reported in association with SS such as cavernous malformations, aneurysms and arteriovenous

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.
