Peliosis hepatis is a rare benign vascular disorder characterised by randomly distributed multiple blood-filled cavities throughout the liver.
These tumors histologically appear as proliferative lesions within the liver often lined by prominent endothelium.
The pathogenesis of peliosis hepatis is still unclear, but is associated with high levels of vascular endothelial growth factor, which has been shown to be activated by parasitism with Bartonella henselae.
The animal may eventually die of a combination of hemodilutional anemia and circulatory failure
