Imaging findings
Chest CT demonstrates diffuse, relatively smooth thickening of the interlobular septa throughout the lungs with some consolidation at the right lung base, simulating pulmonary edema, in a patient with a parotid gland biopsy positive for amyloid.
Key takeaways
Pulmonary parenchymal amyloidosis can manifest as diffuse interlobular septal thickening, mimicking interstitial pulmonary edema or lymphangitic carcinomatosis. It is a rare manifestation of systemic amyloidosis, and its presence can be independent of severe cardiac amyloid involvement.
