CKD patients were further categorized as those clinically diagnosed with diabetes mellitus, hypertension, and other known causes (n = 30) and those of unknown etiology (n = 20).

While it is important for the interpreting physician to be aware of such features, it is of equal necessity that they are aware of potential visual phenomena, such as acoustic streaming in the diagnosis of testicular tumors.
