Intimal Dissection Suspected to Be a Carotid Web That Resolved Spontaneously
Bibliographic record
Abstract
The carotid web (CW) is a shelf-like structure in the posterior wall of the origin of the internal carotid artery (ICA). This report discusses a case wherein surgical treatment was planned for a lesion suspected to be a CW, but the lesion disappeared over time. A 32-year-old male was found collapsed and was admitted to our hospital. Diffusion-weighted magnetic resonance imaging revealed hyperintensity in the left middle cerebral artery. Three-dimensional computed tomography angiography (3D-CTA) and cerebral angiography revealed a shelf-like structure in the posterior wall of the origin of the left cervical ICA. This was diagnosed as left middle cerebral artery occlusion secondary to a CW, which was initially treated medically. Surgical treatment was planned after being transferred from a recovery hospital. However, approximately 3 months later, 3D-CTA and cerebral angiography revealed that the shelf-like structure on the posterior wall of the origin of the left cervical ICA had disappeared. This CW-like lesion may have been an intimal dissection which spontaneously resolved before complete formation of the CW.

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.
