CTICasesLymphangioleiomyomatosis
Imaging findings
CT chest in a young female shows diffuse, thin-walled, round cysts of varying sizes distributed uniformly throughout both lungs, with normal lung parenchyma between the cysts, consistent with lymphangioleiomyomatosis (LAM).
Key takeaways
LAM is a rare, cystic lung disease affecting almost exclusively females. It is characterized by neoplastic proliferation of smooth muscle-like cells (LAM cells) that obstruct airways and lymphatic vessels, leading to diffuse cyst formation and chylous effusions.
