This document discusses the spleen and causes of splenomegaly (enlarged spleen). It begins by thanking radiologists for their assistance. Simple cyst criteria are outlined. Splenogonadal fusion and sarcoidosis are mentioned. The main causes of splenomegaly are then listed, including infections, portal hypertension, hemolytic anemias, hematological malignancies, infiltrative disorders, collagen vascular disorders, and congestive cardiac failure.
