Fig. 6From: Validity of MDCT cholangiography in differentiating benign and malignant biliary obstructionPortahepatis LN due to lymphoma. Malignant obstructive jaundice due to soft tissue mass lesion involving portahepatis LNs of lymphoma. Male patient, 75 years old, presented with dark urine, pale stool, and jaundice. a Axial pre-contrast image showing moderate intra-hepatic biliary radical dilatation. b, c Axial contrast (arterial and portal phase) images showing large ill-defined faintly enhanced soft tissue density mass lesion involving the portahepatis region centered at the confluence of the RT and LT hepatic ducts and encroaching upon the right PV branch. d Coronal oblique MinIP reformatted MDCT cholangiography showing the mass at the portahepatis with its consequent moderate IHBRD. e, f Coronal and sagittal oblique reformatted MDCT cholangiography images showing the soft tissue lesion involving the portahepatis regionBack to article page
