Lymphomas are a heterogenous group of malignancies, all of which arise from a given stage in lymphocyte ontogeny but which have highly variable clinical and imaging manifestations. Immunosuppression from any cause is a well-known risk factor for certain subtypes. Lymphoma may be unifocal, multifocal, or diffuse, affect isolated lymph nodes or any organ system, and demonstrate a range of imaging appearances at almost every site. Primary extranodal lymphoma refers to disease restricted to a single organ, although it can be multifocal. Here we present an imaging spectrum of extranodal lymphoma manifestations involving the CNS, nasopharynx, mediastinal, retroperitoneal, renal and spine.
