Angiomyolipoma

Angiomyolipoma is a (usually) benign renal lesion. Angiomyolipoma of the kidney was previously considered to be a hamartoma or choristoma, but is now known to be neoplastic.^[1] It is composed of variable amounts of fat, vascular, and smooth muscle elements. The fat density of the tumour on CT is pathognomonic. The lesion is well demarcated and contains mature elements. It occurs in more than 50% of individuals with tuberous sclerosis, often bilaterally. Angiomyolipomas also occur in 40% of women who have a rare, cystic lung disease called lymphangioleiomyomatosis, or LAM[1].
