Scoping beyond pulmonary artery involvement; pulmonary involvement in Behcet's disease; a retrospective analysis of 28 patients.

Despite the importance of pulmonary artery involvement and pulmonary thrombosis in Behcet's disease, small-sized pulmonary vasculitis in the form of small vessel involvement is generally overlooked. Our study findings have shown that alveolar hemorrhage and/or ground-glass appearance in the absence of pulmonary artery aneurysm and pulmonary thrombosis are seen commonly as well. Key Points • The characteristics of pulmonary small vasculature involvement in Behcet's disease which is still an area of investigation warrant further attention. • The clinician should bear in mind that the spectrum of pulmonary involvement in Behcet's disease may be variable, but an extensive work up is still of great importance especially in atypical cases.
