CTICasesNodular pulmonary amyloidosis with cystic change
Imaging findings
CT scan shows multiple calcified and ossified pulmonary nodules with surrounding thin-walled cysts.
Key takeaways
Nodular pulmonary amyloidosis can manifest as calcified or ossified parenchymal nodules. The surrounding cysts are hypothesized to result from localized macrophage accumulation and release of matrix metalloproteinases that degrade the adjacent lung parenchyma.
