Introduction. On ultrasound, hepatocellular carcinoma presents with nodular or multinodular lesions of different size and echostructure, sometimes with a surrounding halo, and lateral acoustic shadows or posterior acoustic enhancement. The aim of this study was to determine the incidence of posterior acoustic enhancement in hepatocellular carcinoma. Material and Methods. This retrospective study included 120 patients with pathologically verified hepatocellular carcinoma who had undergone ultrasound examination (using real time ultrasounds from different manufacturers, with 3.5 and 5 MHz probes). Ultrasound imaging focused on the size and appearance of the focal lesions, i. e. echostructure and presence or absence of posterior acoustic enhancement as areas of increased echogenicity behind the lesion. Results. Posterior acoustic enhancement was observed in 47.3% of all nodular hepatocellular carcinomas, whereas this ultrasound phenomenon was statistically significantly more common in the group of tumors from 3 to 5 cm in size. In the group of multinodular tumors, posterior acoustic enhancement was found in 70% of cases. Conclusion. The presence of posterior acoustic enhancement in the detection of focal hepatic lesions may be a significant finding in the diagnosis of hepatocellular carcinoma, especially in patients at risk for developing hepatocellular carcinoma (cirrhosis and chronic liver disease), as well as in monitoring interval growth in size of focal lesions using this ultrasound phenomenon.
