Thoracic Radiographic and CT Findings of Multicentric Castleman Disease in HIV-infected Patients

Multicentric HIV-related Castleman disease (MCD) is a rare and severe disorder of lymphoid tissue inducing high-grade fever, hepatosplenomegaly, and diffuse peripheral lymphadenopathy. During clinical exacerbations, bilateral interstitial pneumonia may occur. In this pictorial essay, we describe different thoracic imaging of MCD, with particular emphasis on computed tomography findings, in 13 HIV-infected patients with histologically proved MCD.
