Endoscopic treatment of distal choroidal artery aneurysm
Bibliographic record
Abstract
Distal choroidal artery aneurysms stemming from the lateral wall of the ventricles are rare and are mostly associated with moyamoya disease. The treatment of these aneurysms is difficult because of their deep location. The authors report the case of a 50-year-old woman followed for moyamoya disease presenting with 2 intraventricular hemorrhages. Cerebral angiography showed an aneurysm located on the left distal choroidal artery. Magnetic resonance imaging also demonstrated that the lesion protruded from the lateral wall of the trigone of the left lateral ventricle. Using MR imaging-guided stereotactic localization, the aneurysm was accurately reached endoscopically and successfully resected from the parent artery. The patient was discharged neurologically intact. To the best of the authors' knowledge, this is the first report of a successfully endoscopically treated distal anterior choroidal artery aneurysm. Endoscopic surgery may be added to the armamentarium of procedures used to treat intraventricular aneurysms.

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.
