Emotional Lability as a Symptom of Extra-axial Posterior Fossa Tumors: A Case-Control Review of Neuroanatomy and Patient-Reported Quality of Life
Bibliographic record
Abstract
Introduction: Emotional lability (EL), the uncontrollable and unmotivated expression of emotion, is a rare and distressing symptom of brainstem compression from extra-axial posterior fossa tumors. In all published case reports, EL is alleviated by surgical resection of the tumor. The primary goal of this study was to radiographically compare the degree of compression from mass lesions onto brainstem structures between EL cases and matched controls. We hypothesized that distortion of brainstem nuclei by mass lesions specifically in the basis pontis region causes EL. Because EL can be a significant social and professional burden, the secondary goal of the study was to compare acute changes in quality of life (QOL) survey scores pre- and postoperatively. We hypothesized that postoperative QOL improvements for patients with EL would be greater than those of matched non-EL control patients.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
