Role of Liver Biopsy in Assessment of Radiologically Identified Liver Masses.

In patients with a radiologically identified liver mass of unclear etiology, liver biopsy/histology made a diagnosis in 95% (277/293) of patients, including 84% (246/293) found to have an oncological malignancy. Liver biopsy/histology also identified malignancy in a high proportion of patients without known underlying cancer. We conclude that liver biopsy is valuable for evaluation of radiologically identified liver masses of unclear etiology.
