Spontaneous conus medullaris infarction in a 79 year-old female with cardiovascular risk factors: a case report.
Bibliographic record
Abstract
OBJECTIVE: To detail the case of a 79 year-old female who presented with sudden bilateral neurological deficits of the lower extremities and was later diagnosed with non-traumatic conus medullaris infarction. The purpose of this case report is to inform primary contact practitioners of the presentation, diagnosis and the associated risk factors of this condition in order to facilitate prompt management. CLINICAL FEATURES: Spinal cord infarction presenting as low back pain with a high degree of bilateral loss of motor strength, sensation and reflexes in the lower extremities and bowel/bladder dysfunction, in a patient with previous coronary artery bypass graft surgery and renal insufficiency. INTERVENTION AND OUTCOME: Referral to emergency within hours of symptom onset allowed for immediate assessment, management and relatively favourable partial recovery. SUMMARY: Although rare, conus medullaris infarction is potentially devastating and requires an appropriate clinical index of suspicion for timely diagnosis, treatment and optimal neurological recovery.

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.
