Extranodal Non-Hodgkin's lymphoma affects up to 30% of patients, frequently involving abdominal organs like the gastrointestinal tract and kidneys. Hodgkin's lymphoma rarely affects organs outside lymph nodes, typically via direct invasion.

Area of Science:

  • Oncology
  • Radiology
  • Pathology

Context:

  • Extranodal Non-Hodgkin's lymphoma (NHL) is a significant clinical entity, occurring in up to 30% of cases.
  • Abdominal organs, including the gastrointestinal tract and kidneys, are frequently involved in extranodal NHL.
  • Hodgkin's lymphoma (HL) involvement of extranodal sites is less common, often resulting from direct extension from adjacent lymph nodes.

Purpose:

  • To present the frequency, imaging morphology, and challenges associated with extranodal lymphoma.
  • To differentiate the patterns of extranodal involvement between NHL and HL.
  • To highlight the diagnostic considerations for lymphoma affecting organs outside the lymphatic system.

Summary:

  • Non-Hodgkin's lymphoma commonly manifests extranodally, particularly in the abdomen, affecting organs such as the gastrointestinal tract and kidneys.

  • While isolated extranodal involvement is rare, secondary infiltration due to systemic disease or relapse is frequent.
  • Hodgkin's lymphoma rarely presents extranodally, with involvement usually secondary to direct spread from pathological lymph nodes.

    • Impact:

    • Improved understanding of extranodal lymphoma distribution and patterns.
    • Enhanced diagnostic accuracy through awareness of imaging features.
    • Facilitation of timely and appropriate patient management for extranodal lymphoma cases.
