What is the most common splenic abnormality?

• A. Splenomegaly
• B. Accessory spleen
• C. Splenosis
• D. Hypersplenism

Answer: (A)

Splenomegaly is the most common splenic abnormality because enlargement of the spleen occurs across a wide range of systemic conditions, from infections and inflammatory diseases to portal hypertension and various hematologic disorders. On ultrasound, you gauge this by measuring splenic size; in adults, a craniocaudal length greater than about 13 cm is commonly used as the threshold for splenomegaly. This broad and frequent enlargement stands in contrast to other splenic issues: an accessory spleen is a normal anatomic variant, splenosis is ectopic splenic tissue usually following trauma, and hypersplenism is a functional consequence that accompanies splenomegaly rather than a separate common abnormality. Because splenomegaly reflects a wide spectrum of disease and is encountered more often than the other conditions, it is the correct choice.
