18F-FDG-PET/CT Pulmonary Infiltrates in Non-Hodgkin Lymphoma Patients Treated with Combined Immunochemotherapy: Incidence and Clinical Characteristics.

Background: Pulmonary infiltrates (PIs) detected in patients with non-Hodgkin lymphoma (NHL) may present a diagnostic challenge due to their wide differential diagnosis, including infection, pulmonary lymphoma and immunochemotherapy-associated pulmonary toxicity.

Objectives: To characterize therapy-associated PIs by positron emission tomography/computed tomography (PET/CT) imaging.

Methods: We conducted a historical analysis of fluorodeoxyglucose-PET/CT (18F-FDG-PET/CT) PIs in NHL patients treated with combined immunochemotherapy including rituximab.
