Amyloid-associated cystic lung disease, a rare condition, often presents with numerous, thin-walled cysts and calcified nodules. It can occur independently or with collagen vascular disease (CVD), and is sometimes linked to MALToma.
Area of Science:
- Pulmonary Medicine
- Radiology
- Pathology
Background:
- Amyloid-associated cystic lung disease is a rare condition.
- It may be associated with collagen vascular disease (CVD).
Purpose of the Study:
- To characterize the clinical, radiological, and pathological features of amyloid-associated cystic lung disease.
Main Methods:
- Review of records for patients with biopsy-proven pulmonary amyloidosis and cystic lung disease on HRCT.
- Analysis of demographic data, CVD association, pulmonary function, pathology, and HRCT findings (cyst/nodule characteristics).
Main Results:
- Twenty-one patients (median age 61) identified; 10/12 had associated CVD (Sjögren syndrome most common).
- Cysts were typically numerous, round, thin-walled, small-to-moderate in size, and peribronchovascular/subpleural.
- Nodules were common (81%), often numerous and calcified (82%); MALToma occurred in 33%.
Conclusions:
- Cystic lung disease associated with amyloidosis can occur with or without CVD.
- Characteristic findings include numerous, peribronchovascular/subpleural cysts and often calcified nodules.
- Pulmonary MALToma is a notable association.
