Splenomegaly at a United States County Hospital: diagnostic evaluation of 170 patients.
Splenomegaly was studied at a municipal teaching hospital in an 11-year retrospective review. The 170 patients were classified into six diagnostic groups. The associated clinical and laboratory features were tested for statistical association (X2), to determine predictive values. Hepatic diseases caused 36% of the splenomegaly; hematologic, 35%; infectious diseases (ID), 16%; inflammatory, 5%; primary splenic, 4%; and other, 3%. The acquired immunodeficiency syndrome (AIDS) occurred in 54% of patients with ID. Hematologic diseases were significantly associated (P < 0.01) with massive splenomegaly, left upper quadrant (LUQ) abdominal tenderness, and all blood "cytoses." The most common disease with massive splenomegaly was myelofibrosis. Surprisingly, hepatic diseases caused 29% of massive splenomegaly. Hepatic diseases were significantly associated (P < 0.01) with hepatomegaly, abnormal liver-function tests (LFT), and blood "cytopenias." Compared with previous reports, both congestive heart failure and endocarditis now rarely cause splenomegaly. All blood "cytopenias" had highly significant associations (P < 0.01) only with hepatic diseases, which suggests that hypersplenism remains a useful concept for the splenomegaly of liver disease.
