Revision 20 for 'Hepatomegaly'All Revisions
Hepatomegaly (an increase in liver size) can result from a vast range of pathologies :
- malignancy / cellular infiltrate
- acquired hepatic conditions
- acquired non hepatic conditions
- congenital anomalies
Assessment of liver size in commonly made on ultrasound or CT, although gross hepatomegaly may be apparent on plain film imaging.
A liver that is longer than 15.5cm in the mid-clavicular line is considered enlarged, however in practice assessment is often subjective. Features that support hepatomegaly include extension of the right lobe inferior to the lower pole of the right kidney and rounding of the hepatic inferior border1.
