Unilateral isolated sphenoid sinusitis with contralateral abducens nerve palsy - A rare complication treated in a low-resource setting
Bibliographic record
Abstract
BACKGROUND: Unilateral isolated sphenoid sinus disease (ISSD) is a rare diagnosis of the paranasal sinuses that can be associated with complications involving vascular, neurologic, and optic structures in close proximity. CASE PRESENTATION: A 62 year old female presented to a hospital in Georgetown, Guyana with right lateral rectus palsy, diplopia, and a severe progressively worsening headache. CT scan revealed an opaque left sphenoid sinus consistent with unilateral ISSD. A transnasal sphenoidotomy was performed without complication under local anesthetic in the absence of endoscopic guidance. The patient's headache resolved immediately after surgery while the diplopia and lateral rectus palsy resolved completely after 6 weeks. CONCLUSION: We present a rare complication of ISSD and highlight challenges associated with diagnosis and management of ISSD in a resource-limited setting. This is the second reported case of unilateral ISSD with contralateral lateral rectus palsy in the literature.

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.
