[Angiomyolipomas (hamartomas) of the kidney. Radiological study apropos of 2 cases. Review of the literature].

Two patients with renal angiomyolipomas studied angiographically are reported:--A case of tuberous sclerosis with bilateral multiple lesions, renal, hepatic and adrenal;--An isolated lesion whose preoperative diagnosis allowed the excision of the tumor. A review of the literature from 1965 to 1977 identified 242 cases of which 177 were isolated angiomyolipomas. There were 54 cases associated with tuberous sclerosis and one with von Hippel-Lindau disease. The radiologic and especially the angiographic signs are illustrated, the hemorrhagic risks are stressed, and the diagnostic features of fetal renal hamartoma are described.
