Spontaneous C1-2 CSF Leak Treated with High Cervical Epidural Blood Patch
Bibliographic record
Abstract
Spontaneous intracranial hypotension (SIH) is a condition caused by spontaneous spinal cerebrospinal fluid (CSF) leaks. Clinically, it is characterized by orthostatic headache and may respond well to epidural blood patch. Other neurological presentations of SIH include diplopia, memory loss, hearing deficits, Parkinsonism, ataxia, obtundation and even coma. Magnetic resonance imaging (MRI) is crucial in the diagnosis of this condition. Typical radiological features include diffuse pachymeningeal enhancement, descent of the cerebellar tonsil, a decrease in the size of prepontine and perichiasmatic cisterns, and subdural fluid collections. However, radiological imaging such as radionuclide cisternography or spinal MRI are not reliable in detecting the site of leakage. Myelography with iodinated contrast followed by thin-cut computed tomography (CT) or MRI of the entire spine has been shown as the technique of choice in defining the location of the CSF leak.

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.
