Abstract
BACKGROUND: Cerebral vasospasm is a rare but devastating complication following pituitary apoplexy. Cerebral vasospasm is often associated with subarachnoid hemorrhage (SAH), and early detection is crucial for proper management. OBSERVATIONS: The authors present a case of cerebral vasospasm after endoscopic endonasal transsphenoid surgery (EETS) in a patient with pituitary apoplexy secondary to pituitary adenoma. They also present a literature review of all similar cases published to date. The patient is a 62-year-old male who presented with headache, nausea, vomiting, weakness, and fatigue. He was diagnosed with pituitary adenoma with hemorrhage, for which he underwent EETS. Pre- and postoperative scans showed SAH. On postoperative day 11, he presented with confusion, aphasia, arm weakness, and unsteady gait. Magnetic resonance imaging and computed tomography scans were consistent with cerebral vasospasm. The patient underwent endovascular treatment of acute intracranial vasospasm and was responsive to intra-arterial milrinone and verapamil infusion of the bilateral internal carotid arteries. There were no further complications. LESSONS: Cerebral vasospasm is a severe complication that can occur after pituitary apoplexy. It is essential to assess the risk factors linked to the cerebral vasospasm. In addition, a high index of suspicion will allow neurosurgeons to diagnose cerebral vasospasm after EETS early and take the necessary measures to manage it accordingly.

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
