Imaging with ultrasound scan (USS) and contrast enhanced computerised tomography (ceCT) demonstrated a 45 mm cystic lesion in the liver hilum (Fig. 1).
(a) Axial T2-weighted MR image demonstrating a fluid and calculus-filled cystic mass within the liver hilum and possibly segments 4b/5 of the liver parenchyma. (b) Coronal maximum intensity projection (MIP) MRCP image illustrates communication between the extrahepatic gallbladder and CBD via the cystic duct. Calculi and biliary sludge is seen within the dilated segment 8 bile ducts. No cystic duct from the intrahepatic gallbladder could be visualised. (c) Cinematic volume rendered technique (VRT) images using magnetic resonance cholangiopancreatography (MRCP) data, which highlights fluid-filled structures. The presence of multiple filling defects within the intrahepatic gallbladder results in the impression of a lobulated mass.
