Abstract
Hemorrhagic facet cysts are a rare condition including both synovial and ganglion cysts. Here, the authors present the first-ever reported case of a hemorrhagic ganglion cyst of the facet joint at L1 to L2 causing cauda equina syndrome. In this report, a 72-year-old woman presented with symptoms of cauda equina syndrome requiring urgent surgical consideration. Magnetic resonance imaging and computed tomography showed an extradural mass at the L1 to L2 level. Due to the giant size of the cyst, there was severe compression of the thecal sac and nerve roots. The patient underwent interlaminar contralateral decompression and cystectomy using a uniportal endoscopic approach. The patient had a quick postoperative recovery, with postoperative magnetic resonance imaging of the lumbar spine showing recovery of the facet cyst with no sign of recurrence or stenosis. This case demonstrates the successful surgical technique of interlaminar endoscopic contralateral decompression combined with cystectomy, showing that a hemorrhagic ganglion cyst at the facet at L1 to L2 can be removed completely under endoscopic view.

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 it
