An umbilical-urachal sinus belongs to the spectrum of congenital urachal anomalies and represents a non-communicating dilatation of the urachus at the umbilical end.
Clinical presentation
Presentation is more common in children and rare in adults.
Radiographic features
An umbilical-urachal sinus can manifest at ultrasound as a thickened tubular structure along the midline below the umbilicus.
Complications
infection, with possible abscess formation
concurrent occurrence of a tumor.
History and etymology
It is thought to have been first described by Cabriolus in 1550 4.
