Lymphadenopathy and organomegaly: diagnostic approach
Also known as Lymphadenopathy · Enlarged lymph nodes · Cervical lymphadenopathy · Hepatomegaly · Splenomegaly · Hepatosplenomegaly · Organomegaly
Fellowship diagnostic approach to paediatric lymphadenopathy and organomegaly: bedside mapping, red-flag recognition, infection–inflammation–malignancy ranking, investigation and biopsy gates, common scenarios (EBV, Bartonella, NTM, TB risk), counselling and exam-ready plans.

Overview & Definition
A lymph node is a filter station for the immune system. Children often have palpable nodes because they meet many new antigens. Lymphadenopathy means nodes that are enlarged, abnormal in character, or present in a pattern that needs explanation. It is a finding, not a final diagnosis. [2] [14]
Organomegaly here means an enlarged liver (hepatomegaly), enlarged spleen (splenomegaly), or both (hepatosplenomegaly). Like nodes, organomegaly is a sign that points to infection, congestion, infiltration, haemolysis, storage disease or inflammation. Your job is to decide urgency, build a ranked differential, and choose the next action that changes care. [14]
Most paediatric cervical lymphadenopathy in large series is infectious or reactive rather than malignant. That fact should calm panic, not stop thinking. You still look for the few children who need same-day work-up. [1] [8]
From doorway lump to plan
- 1
First look
Is the child toxic, struggling to breathe, or showing mediastinal/airway warning signs? Stabilise first.
- 2
Map
Document node sites, size trend, tenderness, mobility, skin change, drainage territory, liver span and spleen tip.
- 3
Sort pattern
Acute localised tender, chronic unilateral cervicofacial, generalised systemic, or high-risk character.
- 4
Act
Observe with safety-net, treat clear bacterial adenitis, test for targeted infections, image, or arrange tissue and specialty review.
- 5
Close the loop
Give return criteria, review timing, and a written problem representation.
