Figure 2 Magnetic resonance cholangiopancreatography findings at first admission. A: A round filling defect was detected at the base of the dilated bile duct, suggesting the presence of a stone (white arrow); B: Magnetic resonance cholangiopancreatography revealed cystic dilation of the intrahepatic bile ducts (black arrow), accompanied with extreme dilation of the common hepatic duct and common bile duct (white arrows), presenting as a large cystic expansion. Hydronephrosis was also visualized (blue arrow); C: Magnetic resonance cholangiopancreatography demonstrated gallbladder atrophy (white arrow), narrowing of the cystic duct (blue arrow), and dilatation at the junction of the cystic duct and common hepatic duct (black arrow); D: Diffusion-weighted imaging identified a layered appearance within the cyst, with the lower layer suggesting bile sludge deposition based on its location and shape (white arrow).
