Congenital urachal anomalies occur when the urachus, an embryologic structure arising from the allantois and urogenital sinus, fail to obliterate. The urachus is a tubular structure extending from the dome of the urinary bladder to the umbilicus. Partial or incomplete obliteration leads to various anomalies including patent urachus, umbilical-urachal sinus, and urachal cyst and vesicourachal diverticulum. These anomalies are uncommon and usually asymptomatic but can present with non-specific abdominal signs and symptoms. Here we describe the embryological and anatomical features of the different urachal anomalies as well as the relevant imaging findings to aid diagnosis and management.
