Using high-resolution linear-array real-time scanners, abdominal ultrasonography was performed in 87 cases with metastatic liver cancers from various primary origins. There were 52 males and 35 females with ages ranging from 20 to 80 years. Seventy-four (85.1%) showed multiple lesions, and 66 (75.9%) had involvement of both lobes. Hypoechoic nodules were found most frequently (39.1%), especially in those cancers with diameters of less than 5cm (47.8%). On the other hand, 91.3% of those lesions with diameters greater than 5cm were hyperechoic. Bull's-eye echofeature was found in 29.5% of the lesions. The sonographic patterns lacked specifity in defining the primary origins. However, lesions metastasized from colorectal organs usually showed hyperechoic features, even though the lesion was small. Twelve (13.8%) cases were noted to have cystic changes and four (4.6%) displayed calcification over their hyperechoic nodules. Serial observations in 9 patients disclosed that follow-up changes of sonographic features correlated well with their clinical conditions.
