Splenomegaly
Splenomegaly is enlargement of the spleen, usually a sign of an underlying disease rather than a problem on its own.
When to get help quickly: Urgent review is needed for sudden severe left upper abdominal pain (which may signal splenic rupture or infarct), especially after trauma or in conditions that weaken the spleen.
Common symptoms
Many people have no symptoms. Others may feel fullness or discomfort in the upper left abdomen, early fullness when eating, or fatigue.
When imaging helps
Imaging confirms the size of the spleen, checks for related findings (lymph nodes, liver changes, masses), and helps narrow the cause.
What radiology does
Ultrasound is the first test; CT or MRI can clarify the cause when needed.
What usually happens next
Treatment is directed at the underlying cause — infection, blood disorder, liver disease, or other systemic illness.
