CT-guided biopsy of peripheral lung lesions associated with BOOP

Diagnosis of Bronchitis Obliterans with Organizing Pneumonia (BOOP), has been carried out thus far by open lung biopsy, or by transbronchial biopsy. We report a patient who presented with fever, cough and dyspnea. A transthoracic CT-guided biopsy of a peripheral lesion resulted in the diagnosis of BOOP. The histological findings were also confirmed by a transbronchial biopsy. It is suggested that transthoracic CT-guided biopsy should be considered for the evaluation of peripheral lung lesion compatible with BOOP.
