Hepatomegaly is the medical term for abnormal liver enlargement (Greek hepar ). It does not refer to a disease itself, but rather an examination finding that has to be interpreted in connection with other findings.
Hepatomegaly can have many different causes, the main ones being:
- Fatty liver : longstanding alcohol abuse, diabetes mellitus , overeating, other chronic liver damage
- Inflammatory diseases: various forms of hepatitis , bacterial infections, malaria
- Cirrhosis of the liver
- Cholestatic liver diseases: biliary atresia , cholangitis
- Iatrogenic causes: drug-toxic effects
- Infiltrative diseases: malignant lymphomas , leukemia , liver tumors
- Masses: cysts , hematoma , bacterial abscess
- Storage diseases (thesaurismoses): glycogenoses , hemochromatosis , fucosidosis , autoimmune diseases
- Heart and vascular diseases: right heart failure, right heart failure , pericarditis , myocarditis
- Miscellaneous and syndromes: sickle cell anemia , achondrogenesis , Klippel-Trénaunay-Weber syndrome
A reliable diagnosis of hepatomegaly is difficult because measurement of the liver size is inadequate due to the variability of the liver shape. It is better to assess the shape of the liver, since with rapid liver enlargement the lower edge of the liver becomes blunt. Furthermore, the angle between the ventral and dorso-caudal liver surfaces can be measured in the sagittal section. With hepatomegaly, the angle is more than 45 °. Pseudo-hepatomegaly, which can occur in obstructive pulmonary disease, must also be excluded.
