The present case revealed a wedge-shaped area with an almost linear boundary and did not show a mass effect in the non-enhanced CT medical images and MR sequence, including chemical shift images. The dynamic contrast enhancement techniques, CTA and dynamic MR imaging, showed irregular enhancement in the abnormal area, which indicated disappearance of the normal vessel structure and was quite useful for diagnosing the medical images metastatic tumor. CTAP showed a wedge-shaped ischemic area. It was suggested that the tumor caused this medical images ischemia due to intrahepatic portal vein blockade. Pathological examination revealed fibrotic liver tissue adjacent to the tumor; this fibrotic tissue contained fewer fat vacuoles than the rest of the liver parenchyma. It was suggested that this fibrotic liver tissue corresponded to the area of focal sparing seen on CT and MR images. In conclusion, the present case was difficult to diagnose because the tumor was hidden within the area of focal sparing, and dynamic contrast enhancement techniques, including CTA, CTAP and dynamic MRI, were useful for diagnosis.
