  • lymphangioleiomyomatosis has cystic lesions with chylous effusions on chest imaging

• small cysts with very thin walls
• usually diffusely distributed with otherwise normal lung parenchyma¹
• small arteries at periphery of cysts indicates perilobular location in relation to lymphatics
• pleural effusion usually can have white appearance and can be chylous (chylothorax is elevated TG with low cholesterol)²

• sometimes can see ground glass opacities from interstitial edema from lymphatic obstruction
• LAM vs PLCH vs LIP vs PBML image, histology, PFT
• LAM has cysts in normal lungs whereas Langerhan has abnormal lungs
