%X The objective of this study was to investigate the prevalence and clinical implications of the hyperechoic rim of liver focal solid lesions. A retrospective review was conducted of sonograms of focal liver lesions with a hyperechoic rim, as well as relative examinations such as computed tomography, magnetic resonance imaging, biopsy, resection, and histopathology reports. A cohort of 10 232 patients was found to have solid focal liver lesions (2030 malignant, 8202 benign). A hyperechoic rim was determined in 182 hemangiomas, 2 granulomas, 2 hepatocellular carcinomas (HCCs), and 4 other malignancies. There were significant differences between malignant and benign lesions (P < .001), between HCCs and hemangiomas (P < .001), between malignancies and hemangiomas (P < .001), between HCCs and granulomas (P = .044), and between other malignancies and granulomas (P = .005). There was no significant difference between liver granulomas and hemangiomas (P = .656). In this study, a hyperechoic rim in solid focal liver lesions appeared mainly in hemangiomas, granulomas, and rarely in malignant lesions
