Fig. 4From: An update on Burkitt lymphoma: a review of pathogenesis and multimodality imaging assessment of disease presentation, treatment response, and recurrenceNodal mass with biliary obstruction. A 55-year-old male presenting with jaundice. a Initial grayscale transverse and sagittal ultrasound images demonstrate an ill-defined hypoechoic mass near the porta hepatis (solid arrow) with associated biliary dilatation. Follow-up MRI with (b) axial post contrast, (c) apparent diffusion coefficient map, and (d) coronal MRCP images demonstrate an enhancing mass with diffusion restriction (solid arrows) encasing and narrowing the extrahepatic bile ducts causing intrahepatic biliary dilatation (dashed arrow)Back to article page
