Learning objectives 1. Review of the findings of lymphoma in extranodal locations.  2. Learning the findings of lymphoma in different organs and systems (primary and secondary involvement). 3. In the patient with diagnosed lymphoma: Know the image patterns that we can find in extranodal locations. 4. In the patient with pathology under study: Keep in mind that lymphoproliferative processes can affect extranodal locations and include them in our differential diagnosis in certain situations.
Read more Background A review of lymphoma extranodal findings was proposed. We compiled a list of lymphoma cases with extranodal involvement through the search platform of our radiological system. Of the cases found, a selection was made based on different criteria (representative cases, rare cases, cases that raised doubts or diagnostic errors). We group the cases by organs and systems. A theoretical review of the extranodal findings of lymphoma was carried out for each of the groups of cases.
Read more Findings and procedure details After carrying out this case selection, we expose a review of lymphoma findings beyond lymphadenopathy in the following locations: Central nervous system. Head and neck. Thyroid. Thorax / mediastinum.  Breast. Gastrointestinal tract. Spleen. Liver. Ovaries. Bone structures. In each section, there is an introductory image related to the lymphoma involvement in the specific location. General data, clinical data, imaging findings, differential diagnosis and treatment are provided. Additionally, for each of the sections, the extranodal findings of lymphoma are reviewed through...
Read more Conclusion Knowledge of the extranodal findings of lymphoma can be useful both in the case of patients with a known diagnosis (search and recognition of findings) as well as in patients with pathology under study (being alert to certain radiological patterns to include lymphoma in our differential diagnosis).  We hope that this presentation has been useful for a general review of this pathology and encourages radiologists to go one step further in their knowledge of the extranodal findings of lymphoproliferative processes.
