Congenital extrahepatic portosystemic venous shunt (CEPS) is a rare anomaly. It causes metabolic derangements and is often associated with liver tumours and other anomalies. Imaging plays an important role in the diagnosis of CEPS. However, it may be misleading in determining the type of shunt. We present a six-year-old girl with CEPS to illustrate the importance of histology in determining the presence of portal veins in the portal triad, which were too small to be seen on imaging.
