[Arteriography in renal metastases from solid tumors (excluding lymphomas). Study of 3 cases and review of the literature].

Three cases of arteriography of renal metastasis of solid tumors are presented. Twice the primitive cancer was bronchial, once laryngeal. There is not other clinical metastasis at the time of arteriography. A general revue of the 19 observations of the litterature is donemthe indication of the arteriography is justified if the primary tumor is not known or if there is not other metastasis. On the cortrary if they are diffused, the indications of this angiography are obviously very limited. In six cases, one can see, as in our observation, stretched thin, encased arteries with a lacune at the nephrographic time. In six other, at these images, are associated rare flecks and neovascularisations; Theses radiological syndromes seem to us characteristic. More rarely the angiography may be normal (3 cases) or look like a primitive renal tumor (3 cases). We must say, however, that nearly all the observations have anatomicaly a renal tumor. The other types of renal metastasis are not well known angiographycally.
