Angiographic manifestations of renal hamartoma.

Two types of renal hamartoma (angiomyolipoma) are presented with emphasis on angiographic findings. Careful analysis of the angiograms can suggest a specific diagnosis. Two important considerations other than angiographic findings are (1) multiplicity of tumors in patients with tuberous sclerosis, and (2) a solitary mass in 40-60-year-old women.
