Eu Leong Harvey James Teo, KK Women's and Children's Hospital
Introduction
The urachus connects the dome of the bladder to the umbilical cord in foetal life. This connection usually involutes at birth. Urachal anomalies occur when the urachus persists beyond birth. These anomalies may cause severe morbidity and mortality due to complications such as infection and malignancy. These anomalies often present in childhood and ultrasound is often the first and only modality needed to diagnose these lesions. The purpose of this poster is to illustrate the sonographic features of these anomalies and their complications.
