BOOP: an important cause of migratory pulmonary infiltrates?

Chlamydial Infection Showing Migratory Pulmonary Infiltrates

“…Idiopathic BOOP, which is now termed cryptogenic organizing pneumonia (COP) (14), is one of the best examples of disease process where fleeting or migratory pulmonary infiltrates can be seen (1)(2)(3). Transbronchial lung biopsies of our patient revealed intraluminal fibrosis of the distal airspaces, which was compatible with COP.…”

“…Migratory pulmonary infiltrates are associated with some diseases (1)(2)(3)(4)(5)(6)(7) including atypical pneumonias such as Mycoplasma pneumoniae and Legionella (7). We recently encountered a patient in whom these radiological findings were due to Chlamydial infection.…”

“…Aetiologically it is either a primary BOOP or secondary to various pulmonary insults like toxic fumes in welding trade as in our case, post infectious BOOP due to chlamydia, legionella, mycoplasma, adenoviruses, cytomegalo virus and influenza virus, drugs related BOOP, secondary to collagen vascular diseases and post transplant BOOP [6]. Various chest radiographic findings have been described in BOOP but the typical chest radiograph shows bilateral peripheral patchy acino nodular infiltrates, migratory in nature in 10 to 25% cases [7]. BOOP may also present as solitary pulmonary nodule, with or without cavitation or linear basal opacities, and may be unilateral.…”

“…The typical chest radiograph shows bilateral, patchy (alveolar) infiltrates. Generally, the infiltrates gradually enlarge from their original site, or new infiltrates appear as the clinical course progresses; however, migratory or mobile pulmonary infiltrates have been reported (20,21).…”
