Trigeminal nerve haemangioma eroding the petrous carotid canal
Bibliographic record
Abstract
OBJECTIVE: To report the first case of mandibular branch haemangioma of the trigeminal nerve causing erosion of the petrous carotid canal. The radiological and histological findings in this case are reviewed. CASE REPORT: A 60-year-old woman presented with severe, right-sided facial pain and paraesthesia. There were no associated symptoms of facial weakness or diplopia. A magnetic resonance imaging scan with gadolinium enhancement was performed. This showed a lesion slightly compressing the right Meckel's cave and eroding the right petrous carotid canal, occupying the foramen ovale and extending to the pterygoid muscle. The lesion was removed via a subtemporal approach. CONCLUSION: Haemangiomas are usually found on the skin and in other soft tissues. However, this rare tumour should also be considered in the differential diagnosis of lesions occupying Meckel's cave and the foramen ovale.

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.
