Figure 11 Non-Hodgkin lymphoma in two different patients with acquired immunodeficiency syndrome. A: Contrast-enhanced computed tomography (CT) at the level of the AP window demonstrates a large mediastinal mass with areas of cavitation with air-fluid levels (arrows); B: Contrast-enhanced CT reveals a large mediastinal mass with low-density foci consistent with tumoral necrosis. There is small left sided pleural effusion in both cases.
