Pathologic and Radiologic Correlation of Adult Cystic Lung Disease: A Comprehensive Review

Figure 1

Lymphangioleiomyomatosis (LAM). High-resolution CT scan in axial (a) and coronal (b) views demonstrating numerous well-defined, thin-walled lung cysts varying in size from 2 to 18 mm. There is diffuse involvement of all lung fields, and the lung parenchyma between the cysts is normal. (c) Thin-walled cystic air spaces interspersed between uninvolved lung parenchymata (magnification ×40). (d) Focal cyst wall thickening from smooth muscle proliferation (arrow) (magnification ×100).
