[A contribution to the diagnosis of renal hamartoma (angiography, sonography, computerised tomography) (author's transl)].

In two cases of renal hamartoma, the examination methods of angiography, sonography and computerised tomography are introduced. Angiography yields the correct preoperative diagnosis. In one of the two cases under discussion, computerised tomography supported the angiographic finding or supplied sufficient proof in itself. In both cases, sonography yielded information on the diagnosis of the space-occupying process only.
