RT Journal Article SR Electronic T1 Cystic lung disease: Systematic, stepwise diagnosis JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 115 OP 127 DO 10.3949/ccjm.82a.14020 VO 82 IS 2 A1 Ha, Duc A1 Yadav, Ruchi A1 Mazzone, Peter J. YR 2015 UL http://www.ccjm.org/content/82/2/115.abstract AB Once cystic lung disease is confirmed on computed tomography, one can arrive at the likely diagnosis in most cases by taking a systematic, stepwise approach based on the clinical and radiographic features. Here, we describe the features of cystic lung disease that point to lymphangioleiomyomatosis, Birt-Hogg-Dubé syndrome, pulmonary Langerhans cell histiocytosis, interstitial pneumonia, congenital cystic lung disease, pulmonary infection, and systemic disease.
