Case list for Metastasis - Breast Cancer
There are 3 CT cases with this diagnosis.
CT demonstrates central hypodense tumor necrosis and ring enhancement on the 10 minute delayed phase indicating desmoplastic stroma reaction (fibrosis). In this case as a effect of treatment. However more peripheral washout of the lesions on delayed images represents viability of malignancy.
Note subtle capsular retraction due to the metastasis in segment 4A (first two images).
First axial CT image of the liver demonstrates appearance of pseudocirrhosis.
CT done six months earlier demonstrates innumerable hepatic metastases (second image).
Baseline CT of this patient before the diagnosis of hepatic breast cancer metastases shows a normal liver (third image).
Six months after chemotherapy treatment, there is significant decrease in size of number and size of metastases. Also, the liver now shows a nodular contour, segmental volume loss and enlargement of the caudate lobe mimicking cirrhosis.
Volume loss and scarring of a large number of treated liver metastases causes retraction of the hepatic capsule, giving the appearance of cirrhosis (pseudocirrhosis), even though no underlying cirrhosis is present.
