"Hepatic angiomyolipomas (AML) are uncommon benign hamartomatous hepatic mass lesions, containing blood vessel (angioid), smooth muscle (myoid) and mature fat (lipoid) components. There is an association with tuberous sclerosis, although this is less strong than for renal AMLs."
"Hepatic angiomyolipomas (AML) are uncommon benign hamartomatous hepatic mass lesions, containing blood vessel (angioid), smooth muscle (myoid) and mature fat (lipoid) components. There is an association with tuberous sclerosis, although this is less strong than for renal AMLs."
"There is a reported correlation between hepatic angiomyolipoma and tuberous sclerosis (TS), although the association is not as strong as it is with renal angiomyolipoma (AML). Up to 20% of renal AMLs are associated with tuberous sclerosis, compared to only 6% of hepatic AMLs 5. Nonetheless, the liver is the second most frequent site of angiomyolipoma after the kidney."
"Angiomyolipomas may be single or multiple, round or lobulated fat-containing mass lesions, seen more commonly in the right hepatic lobe 3."
