Brain Arteriovenous Malformation and Its Implication in Forensic Pathology<sup>*</sup>
Bibliographic record
Abstract
Despite the fact that brain arteriovenous malformations (BAVMs) are a possible cause of sudden and unexplained death, very few papers have discussed their importance in the forensic context. BAVMs consist of tangled masses of tortuous arteries and veins devoid of intervening capillaries that frequently extend from brain parenchyma into the subarachnoid space. Apart from BAVMs, three major groups of vascular malformations of the brain are known: cavernous hemangioma, venous angioma, and capillary telangiectasia. BAVMs and cavernous hemangioma often cause hemorrhages, while venous angioma and capillary telangiectasia are typically asymptomatic. Presented here is the case of a 14-year-old girl who died from a ruptured BAVM. The present case is a reminder that the forensic pathologist should be able to recognize BAVMs and to differentiate it from other types of vascular malformations. Although rare, it is a cause of sudden death not to be overlooked, especially in children.

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.
