The endobronchial survey was normal. BAL fluid was obtained from the lingula and the right middle lobe (RML); transbronchial biopsy sampled the RML. Cytology and culture results for mycobacterium, fungus, and bacteria were negative. BAL fluid test results for cytomegalovirus, chlamydia, Legionella, herpes simplex virus, and respiratory syncytial virus were negative. Lavage profiles demonstrated total counts as follows: WBC, 60,000/μL with 71% lymphocytes, 16% monocytes, 11% eosinophils; and 1% neutrophils in the lingula; and WBC, 230,000/μL with 65% lymphocytes, 16% monocytes, 11% eosinophils, and 7% neutrophils in the RML. CD4/CD8 was 6.38. The transbronchial biopsy specimen showed organizing pneumonia with reactive type II pneumocytes without fibrosis (Fig 2, 3).
