A-D, CT scan of the chest with contrast demonstrates eccentric filling defects in multiple pulmonary artery branches bilaterally (A, D, green arrows) with aneurysmal formation of distal segmental/subsegmental arteries bilaterally (B, D, yellow arrows). A-C, Representative axial images demonstrating bilateral disease involving multiple pulmonary artery branches. D, Representative coronal image.

3. Figure 2
Hematoxylin and eosin stain at low power that demonstrates ectatic vessel that is larger than adjacent airway. Myxoma cells are invading the vascular wall (original magnification × 12.5).

4. Figure 3
Movat stain at higher power that demonstrates the myxoid background breaking down the elastica and invading the perivascular tissue. This Movat stain highlights the connective tissue repair processes in the vessel wall secondary to the tumor invasion. The blue highlights deposition of mucopolysaccharides in the early collagen, and the yellow highlights the more chronic collagen deposition and the irreversible fibrosis (original magnification × 40).

A, Immunohistochemical study of calretinin reveals myxoma cells invading through vessel wall into surrounding alveolar tissue (anticalretinin with hematoxylin counterstain; original magnification × 40). B, Myxoma cells with brown staining from anticalretinin antibody (anticalretinin with hematoxylin counterstain; original magnification × 400).
