pulmonary cysts; lung cyst
Definition: A lung cyst is an air-filled lucent structure surrounded by a thin wall. The presence of multiple intrapulmonary cysts is defined as cystic lung disease.
Although cystic lung disease is rare, incidental detection has increased significantly in recent years by screening using computed tomography.
There are many conditions that can mimic lung cysts and cause cystic lung disease.
Clinical, radiographic, and histologic findings are all necessary for a proper diagnosis, and multidisciplinary approaches are frequently required.

- The BHDS-cysts are likely to develop at the periacinar region, an anatomically weak site in a primary lobule, where alveoli attach to connective tissue septa. (#24393238#)
- BHDS cysts possibly expand in size as the alveolar walls disappear at the alveolo-septal junction and grow even larger when several cysts fuse. (#24393238#)
