It is seen in patients with liver metastasis, mostly from breast cancer.This side effect is rare and not well known since only a few publications discuss it. Importantly, radiologists have to know it since the imaging findings are readily confounded with a progression of underlying malignancy. Patients with pseudocirrhosis have a high risk of liver failure and changing the chemotherapeutic regimen can prevent early death. Background Pseudocirrhosis is a radiologic term that describes morphologic changes in liver parenchyma due to the toxicity ofsome chemotherapeutic drugs. It is seen in patients with liver metastasis, mostly from breast cancer.This side effect is rare and not well known since only a few publications discuss it. Importantly, radiologists have to know it since the imaging findings are readily confounded with a progression of underlying malignancy. Patients with pseudocirrhosis have a high risk of liver failure and changing the chemotherapeutic regimen can prevent early death. Findings and procedure details The term pseudocirrhosis refers to a liver parenchyma resembling macronodular cirrhosis due to retracted tumor tissue and scarring between areas of regenerative parenchyma[i]. These morphologic changes are caused by a combination of degenerating liver metastasis and direct hepatototoxic effects of chemotherapy. The shrinkage and distortion of the liver can be indistinguishable from end stage liver disease. It typically occurs within a few months after the onset of chemotherapy. Analytic parameters can be normal in the beginning but if the cytotoxic therapy continues, patients can end up with liver failure. In some documented cases, the discontinuation of chemotherapy lead to acomplete restitution. Most of the patients suffer from metastatic breast cancer but cases of pseudocirrhosis in patients with lymphoma, melanoma, renal or lung cancer, liver metastasis paired with a prolonged chemotherapy were also described in the literature. Pseudocirrhosis can be a side effect of different therapy regimens, for example Placitaxel, Trastuzumab, Docetaxel or Cisplatin. Page 2 of 9 Imaging findings are similar to those of normal cirrhosis, including diffuse nodularity, enlargement of the caudate lobe and even portal hypertension with ascites[ii][iii]. More specific findings are multifocal capsule retraction due to degenerating liver metastasis. Typically the cirrhosis progresses rapidly in patients with no underlying hepatopathy but a history of chemotherapy. The only way to distinguish pseudocirrhosis from real liver cirrhosis is a liver biopsy. Histological findings in pseudocirrhosis differ from real cirrhosis in the presence of bridging fibrosis in real cirrhotic liver parenchyma[iv]. We present images from abdominal sonography and abdominal contrast enhanced multy detector CT (MDCT) of cases from our centre. The pre- and post treatment findings are documented (Figure 1 to 6). Images for this section: Fig. 1: 40 year old female with metastatic breast cancer. No history of liver disease. Pre treatment abdominal CT. Liver with normal morphology. Some hypodense liver metastasis. Page 3 of 9 Fig. 2: Same patient at the beginning of Chemotherapy (Capecitabine and later Doxorubicin). Page 4 of 9 Fig. 3: Same patient, three months after starting of Chemotherapy. Discrete lobulation of hepatic surface. Page 5 of 9 Fig. 4: Same patient, 9 months after onset of chemotherapy. Diffuse hepatic shrinkage and lobulation. Perihepatic ascitis. Page 6 of 9 Fig. 5: Another patient, female with metastatic breast cancer. Abdominal sonography before chemotherapy shows morphologically normal liver with metastasis. Page 7 of 9 Fig. 6: The same patient, only three month later. Chemotherapy has been given for about two month. The image shows lobulation of the liver contours, volume loss of the organ and important ascitis. Page 8 of 9 Conclusion Radiologists shouldbe aware of the risk of developing pseudocirrhosis in certain patients with chemotherapy due to liver metastasis. It is important to know this diagnosis and to communicate it to the attending physician so that the chemotherapeutic regimen can be changed early.
