One response to “Big kidney little kidney”
The right kidney is
The right kidney is definitely enlarged while the left kidney looks normal in size. Both kidneys are heterogenous with some loss of architecture in the left kidney. The enlarged right kidney has basically maintained architecture with ill defined hypoechoic nodules.
The polycloncal gammopathy may indicate infection or immune mediated disease or FIP if an infection or imune mediated disease is not identified. FIP is not as common in adult cats but surely its possible. You can also see polyclonal gammopathy with neoplasia so neoplasia cant be ruled out.
I don’t think Toxo really has an effect on the kidneys, maybe except for possible cyst formation in visceral disease? I cant think of an effect Toxo has on the kidneys…I think more CNS and maybe acute liver disease with Toxo.
It looks like there is thickened SI and maybe pancreatic inflammation in the clip of the LK.
I think I would put neoplasia / Lymphoma, FIP and nonspecific nephritis at the top of the list with the enlaged RK with nodular changes. FNA of the RK cortex using 25 ga needle and with normal coag panel would be the next move pending the testing.
