Ultrasonography of Necrotic Hepatic Metastases

Abstract

Twelve patients with sonolucent hepatic metastases studied with gray scale ultrasonography are presented. Extensive necrosis presumably accounts for the sonolucent appearance of the hepatic lesions. The spectrum of ultrasonographic features and correlations, particularly with computed tomography, are presented. The similarity between anechoic hepatic metastases and benign conditions of the liver is emphasized.
