Hepatomegaly is a condition in which the liver is enlarged, generally greater than 15 centimeters in the midclavicular line. However, normal liver size varies by person depending on the person’s sex, age, height, weight, and body size. Hepatomegaly develops primarily as a result of a pathologic process which should be investigated further. Hepatomegaly may be suggested from the physical examination or found on imaging studies. Like any physical or radiologic finding, the clinical context of this finding should guide further work-up and treatment^[1].
