Tumors of lymphoid and hematopoietic tissues

Hematolymphoid neoplasms represent the third most common malignancy in children and young adults. These are heterogeneous diseases that can involve lymph nodes and extranodal sites with variable clinical presentations. Appropriate imaging studies combined with sufficient diagnostic material for pathological evaluation are required for an accurate diagnosis to be established. Additionally, radiological studies are now the standard of care for lymphoma staging and are also essential in evaluating treatment response for some lymphoid tumors. The aim of this chapter is to provide relevant and current knowledge on the combination of radiologic and pathologic studies as part of the evaluation and diagnosis of common childhood hematolymphoid tumors.
