Abstract

fetched live from OpenAlex

BACKGROUND: Cutis verticis gyrata (CVG) is a rare benign scalp condition that causes the formation of skin ridges and furrows. Because of the altered scalp anatomy, this condition can pose unique challenges in neurosurgical procedures. OBSERVATIONS: The authors report the case of a 47-year-old man with CVG and neurosarcoidosis who developed hydrocephalus requiring a ventriculoperitoneal shunt. Initial shunt placement at Kocher's point proceeded without complications. However, the patient presented several months later with shunt failure caused by migration of the proximal catheter. The cause of this was determined to be related to the patient's scalp hypermobility. After shunt revision and fixation of the hardware using titanium plates and screws, the patient had an uneventful recovery and a stable outcome at follow-up. LESSONS: This case emphasizes the importance of preoperative planning and intraoperative measures tailored to CVG patients. Further research is needed to elucidate the condition's neurosurgical implications and optimize procedural outcomes. https://thejns.org/doi/10.3171/CASE25174.

Teacher imitation

Not 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.
