Full Definition
Splenomegaly refers to abnormal enlargement of the spleen beyond normal size parameters for age. In pediatric hematology, splenomegaly is frequently observed in conditions such as sickle cell disease, thalassemia, leukemia, and hereditary spherocytosis. The enlarged spleen may cause pain, early satiety, and increased risk of splenic sequestration or rupture, requiring regular monitoring through physical examination and imaging studies.
