Open lung biopsy (OLB) is unnecessary to diagnose the condition, and TBLB is a usefuladjunct although bronchoalveolar lavage(BAL) fluid analysis is often sufficient for its diagnosis(4). WE describe a case of PAP with typical radiological features and failure of an ntial BAL to conform its diagnosis but TBLB did.
Bronchoscpic lung crybiopsy (BLC)is a novel bronchoscopic technique of obtaining lung biopsy (figure 1). It involves the bronchoscopic placement of a flexible cryoprobe inside the lung parenchyma, freezing the probe and shearing out the lung tissue frozen around the tip.
