Hepatosplenomegaly (commonly abbreviated HSM) is the simultaneous enlargement of both the liver ( hepatomegaly) and the spleen ( splenomegaly). Hepatosplenomegaly can occur as the result of acute viral hepatitis, infectious mononucleosis, and histoplasmosis or it can be the sign of a serious and life-threatening lysosomal storage disease. Systemic venous hypertension can also increase the risk for developing hepatosplenomegaly, which may be seen in those patients with right-sided heart failure.
