Overview

Angiomyolipoma may be classified according to radiologic appearance into 7 subtypes: classic angiomyolipoma, triphasic angiomyolipoma, fat poor angiomyolipoma, hyperattenuating angiomyolipoma, isoattenuating angiomyolipoma, angiomyolipoma with epithelial cysts, and angiomyolipoma in lymphangioleiomyomatosis.^[1]

Classification

Angiomyolipoma may be classified according to World Health Organization (WHO) into as follows:^[1]^[2]^[3]^[4]


Radiologic Classification	Features

Classic angiomyolipoma	Abundant fat Fat tissue in renal sinus
Triphasic angiomyolipoma	Mature adipose tissue Dysmorphic blood vessels
Fat poor angiomyolipoma	Minimal fat tissue Abundant smooth muscle component
Hyperattenuating angiomyolipoma	Abundant smooth muscle component Hyperattenuating tissue
Isoattenuating angiomyolipoma	Scattered fat tissue Smooth muscle component
Angiomyolipoma with epithelial cysts	Epithelium lined cysts Fat poor
Angiomyolipoma in lymphangioleiomyomatosis	Atypical smooth muscle component Cystic changes
