Isolated third cranial nerve palsy as the presenting sign of tuberculum sellae meningioma: a case report
Bibliographic record
Abstract
Tuberculum sellae meningioma (TSM) is an uncommon tumor among all intracranial meningiomas. As these tumors grow, they compress the surrounding structures, including the optic nerves and the pituitary gland. Ocular motor nerve palsy (OMNP) can occur as an isolated mononeuropathy or as part of multiple cranial nerve palsies. The role of corticosteroids in the management of OMNP has not been fully studied in the literature. In this report, we present a case of a previously well middle-aged woman who presented with severe headache and isolated OMNP on examination. MRI of the brain showed a small TSM that extends into the right optic canal. In our case, we noted the expedient and complete recovery of isolated OMNP within a few days following treatment with dexamethasone. This case report is on an isolated OMNP associated with TSM, which has not been previously reported. In addition, it highlights the role of corticosteroids in achieving rapid recovery from OMNP.

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.
