Distinctive imaging features of liver metastasis from gastric adenocarcinoma with enteroblastic differentiation: A case report

Figure 1 Contrast-enhanced computed tomography. A: Plain computed tomography revealed a low-density tumor with a diameter of 30 mm located in segment 7; B: In the arterial phase, the tumor showed an oval shape with predominant peripheral enhancement; C: In the portal phase, the enhancement observed in the arterial phase was diminished; D: In the delayed phase, the peripheral area of the tumor became indistinguishable from the surrounding liver parenchyma, while the central area showed progressive enhancement.
