Detecting a Canal of Nuck Hydrocoele in a Child with a Ventriculoperitoneal Shunt Using POCUS
Bibliographic record
Abstract
In females, failure of the processus vaginalis to close properly can result in continued outpouching of the parietal peritoneum through the inguinal canal into the labia majora, forming a structure known as the Canal of Nuck. In rare cases, a Canal of Nuck hydrocoele can develop in association with the presence of a ventriculoperitoneal (VP) shunt, leading to symptoms of pain and discomfort in the inguinal region. We present the first reported case of a Canal of Nuck hydrocoele identified using POCUS in a child. This case highlights the role of POCUS as a safe, reliable, first-line imaging tool for identifying Canal of Nuck hydrocoeles in patients with VP shunts.

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.
