Learning objectives
Pseudocirrhosis is a radiologic term that describes morphologic changes in liver
parenchyma due to the toxicity of some chemotherapeutic drugs[i]. 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.

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).

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.

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.
