Anterior Choroidal Artery Aneurysm Associated With Moyamoya Disease
Bibliographic record
Abstract
The clinical course and management of anterior choroidal artery (AChoA) aneurysms associated with moyamoya disease (MMD) have not been fully clarified. A 61-year-old man experienced dysarthria. CT revealed hemorrhage in the lateral ventricles, and an aneurysm in the left lateral ventricle. MRI performed 13 months prior to the onset showed no aneurysm. Angiography on admission demonstrated an aneurysm of about 4 mm in diameter on the left anterior choroidal artery. Repeated angiography on the ninth day showed enlargement of the aneurysm. However, MRI and angiography demonstrated the disappearance of the aneurysm on the 17th day. On the 38th day, superficial temporal artery-middle cerebral artery bypass was performed to decrease the hemodynamic stress on the distal arteries. Follow-up angiography showed no recurrence of the aneurysm. This is the first reported case of a distal anterior choroidal artery aneurysm, which was previously undetectable, showing enlargement followed by spontaneous disappearance. Distal aneurysms associated with MMD occasionally regress. Therefore, close radiological observation is necessary. J Neurol Res. 2016;6(1):24-27 doi: http://dx.doi.org/10.14740/jnr371w

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.
