Key findings in Lymphangiomyomatosis: Numerous thin-walled cysts, surrounded by normal parenchyma. Cysts range from 2mm to 5cm in diameter, are round in shape and more or less uniform. Cysts are distributed diffusely throughout the lungs and upper and lower lobes are involved to a similar degree. Wall thickness of the cysts ranges from barely perceptible to 4 mm. Mediastinal or hilar adenopathy and pleural effusions (40%). Recurrent pneumothorax (40%). On the left a typical case of LAM with multiple evenly spread thin walled cysts complicated by a pneumothorax. #Clinical #Radiology #CTChest #Lymphangiomyomatosis #LAM #Cystic #RadiologyAssistant
