Fig. 5From: CT and MRI features of hepatic epithelioid haemangioendothelioma: a multi-institutional retrospective analysis of 15 cases and a literature reviewA 36-year-old female with pathologically diagnosed HEHE. Axial unenhanced T1-weighted MRI (a) demonstrates a hypointense tumour in segment 6 of the liver, which is hyperintense on axial fat-suppressed T2WI (b) and DWI (c). On contrast-enhanced images of three phases (d, f), the tumour presented enhancement pattern A, with peripheral irregular enhancement on arterial phase (d), with centripetal progressive filling on the portal venous phase and (e) equilibrium phase (f) along with gradually increasing intensification, and a “lollipop sign” can be seen on portal venous phase. The tumour manifested as a homogeneous hypo-intensity on the HBP (g). There were other lesions (arrows) in the upper part of the liver on the arterial phase (h) with pathologically proven epithelioid haemangioendotheliomaBack to article page
