1.This paper presents an update of the most common pathologies that may affect the inguinal canal in neonates and infants, especially those related to the closure failure of the processus vaginalis, using ultrasonography as the imaging modality of choice. 2. Depending on the degree of processus vaginalis obliteration failure, different conditions may develop, such as non-communicating and communicating hydroceles, funicular hydrocele, spermatic cord cyst, cyst of the canal of Nuck, cryptorchidism and indirect inguinal hernia, conditions that will be shown in our presentation. 3. Despite being a less common in children, we also selected a case of direct inguinal hernia. 4. In some cases, early and accurate diagnosis is urgent to avoid possible complications, for example, incarcerated or strangulated inguinal hernia, or ovary herniation into the inguinal canal.
