Bronchiolitis obliterans organizing pneumonia is a rare disease characteriz
ed by the presence of granulation tissue within alveolar ducts and alveoli.
Most cases are idiopathic, but it may also be seen during resolution of vi
ral or bacterial pneumonia (mycoplasma, legionella and chlamydia). It may p
resent as a community acquired pneumonia which does not respond to antibiot
ics, which make the diagnosis very difficult. We described a 53-year old pa
tient who presented with Bronchiolitis obliterans organizing pneumonia duri
ng the resolution of pseudomonas aeruginosa pneumonia. Initially there was
slight improvement on antibiotics but later he became severely hypoxic and
placed on mechanical ventilator. Diagnosis of Bronchiolitis obliterans orga
nizing pneumonia was obtained with bronchoscopic lung biopsy. He showed an
excellent response to steroid treatment. To our knowledge this is the first
case of Bronchiolitis obliterans organizing pneumonia secondary to Pseudom
onas aeruginosa pneumonia.
