Imaging findings
High-resolution CT shows slowly progressive, patchy ground-glass opacities, septal line thickening, and dense, consolidated airspace opacities predominantly in the lower lobes and the lingula.
Key takeaways
Alveolar septal amyloidosis is a rare, slowly progressive form of pulmonary amyloidosis associated with plasma cell dyscrasias. It presents with interstitial and septal thickening that can mimic lymphangitic carcinomatosis or lipidic-predominant adenocarcinoma, but can be distinguished by its slow progression and confirmation via lung biopsy showing amyloid deposition.
