CTICasesPulmonary Amyloidosis
Imaging findings
Massive interlobular septal thickening and focal large opacities, which were FDG-avid.
Key takeaways
Septal amyloidosis should be considered when significant, non-edematous septal thickening is present. It can show FDG uptake and potentially lead to secondary cystic lung disease via giant cell-mediated matrix metalloproteinase release.
