Isolated Lower Limb Weakness Following Hemorrhagic Stroke: A Case Report
Bibliographic record
Abstract
Isolated limb weakness (monoparesis) has many possible etiologies. Although often assumed to be of a peripheral cause, it can be of central origin. This article describes a case from the Emergency Department of left lower limb weakness in a walk-in male patient on no medications, who had a 50-pack-year smoking history, type II diabetes, and asymptomatic atrial fibrillation. The patient had no history of previous episodes or trauma. His vitals were normal, and his speech and facial function were intact. The patient had full function of his upper limbs, no sensory deficits, and equal reflexes bilaterally. The singular clinical finding was decreased strength in the left leg compared to the right. Imaging revealed a right frontal intraparenchymal hemorrhage, which remained stable throughout his hospital admission. His muscle weakness was significantly improved upon discharge. In general, strokes can present with a variety of symptoms, which increase the risk of misdiagnosis. Monoparesis can be the singular sign of a stroke, and it is more common in the upper than the lower limbs.

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.
