Detecting a Canal of Nuck Hydrocoele in a Child with a Ventriculoperitoneal Shunt Using POCUS

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.
