What is the meaning of this sonographic report: liver is enlarged with increased parenchymal echogenicity. there is an irregular, thick-walled heterogeneous mass in the right hepatic lobe, likely segment vii/viii measuring approximately 5.5 x 5 x 5?

The U/S report of a mass that large requires a CT or MRI to determine if the mass is vascular or potentially malignant. Vascular abnormalities do not always require surgical solutions. See your physician for further testing.

An enlarged liver with increased echogenicity most commonly is seen when there are fatty changes of liver. The mass in right lobe, I will assume is about 5 cm in size. (Centimeters are common units used), If this is the case, the mass is about 2 inches and should be further evaluated. Some are benign such as hemangioma and can be better studied with MRi or CT. If it's not, a biopsy may be needed.
