Kaposi Sarcoma/Human Herpesvirus 8 (HHV-8)
Kaposi sarcoma, pulmonary: chest X ray
Chest radiograph of an HIV-infected man, CD4 count of <100 cells/µL, demonstrating bilateral, predominantly middle and lower lung zone abnormalities in a central distribution. The abnormalities include a central coalescent pattern with smaller, nodular opacities best seen in the periphery of the upper lung zones. Kerley B lines can be appreciated at the bases. This constellation of findings in an HIV-infected man is suggestive of pulmonary Kaposi sarcoma (KS). The diagnosis was confirmed by bronchoscopic visualization of the characteristic KS lesions seen throughout the tracheobronchial tree.
