    Introduction: To evaluate the spectrum and frequency of abnormal chest multidedector computed tomography (MDCT) findings in Behcet's disease(BD). Materials and Methods: Chest MDCT scans of 44 patients referred to radiology department for chest symptoms those had prior or newly established diagnosis of BD between 2009-2016 were retrospectively reviewed. Abnormal findings within pulmonary artery (PA), lungs, other large vessels, heart, mediastinum, pleura and pericardium were noted. Results: Sixteen patients had one ore more computed tomography (CT) findings related to BD. PA involvement was most common (27.2%) presentation revealing thrombosis in 8 and aneurysms in 4 of 12 patients. Mean PA diameter was 29 +/- 3.7 mm. Patients with PA involvement had significantly higher PA diameters than those without (p< 0.001). Hypertrophied bronchial artery seen as serpiginous vessels around hilum was a common finding (66.6%). Lung parenchyma findings was rarely isolated and usually associated with PA involvement with subpleural alveolar opacities, focal atelectasis and ill-defined nodular opacities. Cardiac filling defects were accompanying lesions in most of patients with PA aneurysms (75%). Conclusion: BD is associated with a wide spectrum of simultaneous involvement of discrete anatomical sites. PA enlargement and hypertrophied bronchial artery is a clue for patients with PA involvement. Heart chambers should be checked for filling defects particularly in patients with PA aneurysms.
