Inflow Angle of Small Paraophthalmic Aneurysms Is a Determinant of Adjacent Sphenoid Bone Remodeling
Bibliographic record
Abstract
OBJECTIVE: Large internal carotid artery aneurysms can cause remodeling of the sphenoid bone with subsequent hemorrhage into the sinus. No reports have demonstrated small unruptured lesions causing similar bone remodeling. The purpose of this study was to demonstrate our experience with small unruptured paraophthalmic aneurysms causing sphenoid bone remodeling, specifically when the optimal aneurysm inflow angle is present. METHODS: We searched our database for computed tomography angiography studies of small paraophthalmic aneurysms and assessed adjacent sphenoid bone remodeling and inflow angle. RESULTS: We found that aneurysms causing sphenoid remodeling represent 19.51% of all small paraophthalmic aneurysms at our institution and that the average inflow angle for these aneurysms was 94.38 degrees, significantly greater than for those not causing remodeling. CONCLUSIONS: Our findings add support to using computed tomography angiography in the follow-up of aneurysms to assess surrounding bone changes and to the development of a more evidence-based approach in the management of small paraophthalmic aneurysms, which currently may be managed conservatively.

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.
