Presumed arachnoid cyst and acquired isolated third nerve palsy in a child-causal or incidental?
Bibliographic record
Abstract
Arachnoid cysts and oculomotor palsy are rare occurrences in children. This report describes a case of acquired third cranial nerve palsy in a child, caused by compression of the oculomotor nerve by an arachnoid cyst. Nineteen-month-old female child presented with a history of squinting in the right eye. Magnetic resonance imaging (MRI) of the brain showed a small cystic lesion immediately adjacent to the cisternal segment of the oculomotor nerve. Immediate surgical intervention was deferred. Follow-up after 6 months showed progression of third nerve palsy with no change in size of the cyst. This case highlights the importance of performing neuroimaging to rule out the presence of compressive lesions in children with abnormal ocular motility and pupillary findings. Small insignificant lesions on MRI need to be followed up in such cases to explain the findings as in our case.

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.
