Imaging the lungs in patients treated for lymphoma

The lymphomas are a heterogeneous group of malignancies, which exhibit a range of different molecular features, genetics, and clinical presentations. Consequently, therapeutic approaches and clinical outcomes differ greatly. Following therapy, the thorax may be a site of disease recurrence, but infection, drug reactions, and radiation pneumonitis are commonly encountered. We present a comprehensive review of these conditions, focussing on their radiological appearances, in order that radiologists may better engage their colleagues in haemato-oncology.
