Thoracic imaging of pediatric lymphomas

Lymphoma (Hodgkin and non-Hodgkin types) is the most common intrathoracic n eoplasm in the pediatric age group. Diagnostic strategies and treatment app roaches for these tumors are largely determined by protocols established by one of the large, multi-institutional cooperative groups. In this paper, H odgkin and non-Hodgkin lymphoma is discussed in the context of these cooper ative group protocols. The basic biology, patterns of primary and metastati c disease distribution, treatment approaches, imaging follow-up, and areas of active research are discussed.
