Thank you Maralee for an interesting presentation of cough and dyspnea in a patient post-bone marrow transplant.  What further work-up is indicated with this representative CT scan?

This patient’s chest x-ray show a right upper lobe consolidation, which was more evident on CT scan.

The patient underwent bronchoscopy with bronchoalveolar lavage and transbronchial biopsy, which confirmed the diagnosis of organizing pneumonia with the presence of granulation tissue within the alveolar ducts and air sacs
