Liver lesions

Liver lesions represent a heterogeneous group of pathology ranging from solitary benign lesions to multiple metastases from a variety of primary tumors.

Liver lesions may be infiltrative or have mass-effect, be solitary or multiple, benign or malignant.

Assessment of liver lesions takes into consideration their appearance and vascularity on a variety of imaging modalities:

• cystic liver lesions
• hypervascular liver lesions
• liver tumors

The differential diagnosis for pediatric liver lesions is different to that for an adult.
