Abstract
We report a case of liver pseudotumor that consisted of blue liver that was caused by an adverse effect of chemotherapy. A 45-year-old woman was given a diagnosis of rectal cancer and underwent a laparoscopic high anterior resection with D3 lymph nodes dissection. As adjuvant chemotherapy, she received 9 courses of modified FOLFOX6. Enhanced abdominal CT scan, at 6 postoperative months, showed low-density areas in the liver of segments 5/8 and segment 4. MRI revealed the same findings, suggesting metastatic lesions, therefore we performed a hepatic resection. Operative findings showed congestive lesions in S5/8. The frozen section of the area demonstrated sinusoidal dilatation without malignancy. Permanent specimens confirmed the lesions as pseudotumor consisting of blue liver. In this case, it was difficult to differentiate the metastatic liver tumor from the pseudotumor by modern imaging modalities such as CT and MRI.
