Different imaging findings of inflammatory myofibroblastic tumor of the liver

Figure 3 Axial contrast enhanced computed tomography images of the liver inflammatory myofibroblastic tumor. A: Axial arterial phase images showing a hyperenhanced mass well defined at the periphery of the mass; B: Arterial phase images showing a liver lobe artery (dash arrow) around the mass and the front edge of the mass lay a low density nodule (solid arrow) not enhancing in three phase images; C: Axial portal venous phase images showing a further enhanced corresponding to the arterial phase images; D: Axial delayed images showing obviously wash-out corresponding to the arterial phase images.
