Abstract: The urachus is a tubular, midline structure, located preperitoneal in the centre of a pyramidal shaped space, lined by obliterated umbilical arteries with its base on the dome on the bladder and the tip directed towards the umbilicus. Abnormalities in the closure of the intraembryonic portion of the allantoic lumen result in urachal abnormalities. Incidence of Urachal sinus is about 15% and is more common in children, rare in adults. Here we are presenting a rare case of a 24-year-old male who presented with swelling and discharge from umbilicus and on clinical examination and investigations with USG and cystogram was diagnosed to have urachal sinus which was treated surgically by excision. Histopathology report of the excised tract showed features suggestive of urachal sinus. Post operative period was uneventful.
