<s>[INST] my ultrasound report shows fatty liver changes, intraluminal echoes noted in urinary bladder , minimal pelvicalyceal system prominence in left kidney what does this mean? [/INST] Hi,  Fatty liver means small globules of fat deposited in the liver. Most commonly it is because of alcohol consumption. It could also be because of high fat diet for long duration. Fullness in pelvicalyceal system means mild swelling or dilatation of kidney. It Could be because of obstruction by stone or some congenital narrowing. It can also be a normal variant. </s>
