Intra and extrahepatic bile ducts are dilated and CBD measured 11 mm in caliber. An 8 mm low signal filling defect is present at distal of CBD inferring stone. Additionally, a few small stones are seen in gallbladder.
Case Discussion
Magnetic resonance cholangiopancreatography (MRCP) has largely replaced ERCP as the gold standard for diagnosis of choledocholithiasis, able to achieve similar sensitivity (90-94%) and specificity (95-99%) without ionizing radiation, intravenous contrast, or the complication rate inherent in ERCP.
