Biliary atresia is one of the commonest causes of prolonged jaundice in neonate, whereas cystic biliary atresia is a rare form of biliary atresia with similar presentation, but a slightly different sonographic finding. Being able to differentiate them radiologically is important as the surgical management is different for these two diagnoses. An ultrasound examination was done for a 2-month-old baby girl with prolonged jaundice with the finding of a cyst along the portal triad, which raised the suspicion for cystic biliary atresia. The diagnosis was confirmed with intraoperative cholangiography (IOC) and Kasai procedure was done. The patient was well after the surgery with resolution of jaundice.
