[Renal amyloidosis. An echographic study of 7 cases]

Seven patients suffering from renal amyloidosis (2 primitive and 5 secondary) underwent US examination. The results show a strict correlation between US findings and the pathologic changes produced by this condition. US proves to be especially useful in the early stages of the disease: its results, together with the clinical data, may in fact be highly suggestive of the correct diagnosis. On the contrary, in the late stages of renal amyloidosis, when pathologic changes lead to progressive nephrosclerosis, US findings appear aspecific, since they are undistinguishable from the patterns observed in other renal medical disorders.
