Chronic airspace disease: Review of the causes and key computed tomography findings

Figure 7 Angio-invasive aspergillosis. A 35-year-old woman with history of acute myeloid leukemia and severe neutropenia presented with cough and pleuritic chest pain. A: Computed tomography of the chest at the time of presentation showed a wedge-shaped pleural-based opacity (*) and consolidation with peripheral ground glass opacity (arrow) consistent with a halo sign, highly concerning for angio-invasive aspergillosis given the history; B: Despite appropriate therapy, the opacity persisted on 6 wk follow-up chest computed tomography (arrow).
