Objectives:
@EN Ultrasonography(USG) is widely used for the screening and detection of liver SOL in patients with acute and chronic hepatopathy, but the prevalence of liver SOL on a nonselected population by ultrasonographic screening examination is not well
know.
We experienced some patients with liver SOL in a automated med-screening center visitor by USG and reviewed the prevalence and clinical aspects of liver SOL detected by USG in a view of dynamic relation to hepatoma.
@ES Methods:
@EN From March 1983 to April 1994, USG was performed on 27,140 visitors from a urban and suburban area of Taegu city. Initial USG of the liver was followed by follow up USG and other imaging modalities in case it was necessary.
@ES Results:
@EN 1) Liver SOL was detected in 337 cases(12.4%) of 27140 examinees by initial screening USG.
2) Among 337 cases of liver SOL 226(67.1%) of cyst, 19(5.7%) of hepatoma, 15(4.5%) of hemangioma, 12(3.6%) of polycystic kidney, 2(0.6%) of metastatic cancer, 1(0.3%) of abscess, 22(6.5%) of false positive finding without SOL and 40 cases(11.9%)
of
nonspecific questionable SOL without confirmation were noted at the end.
3) The sensitivity of USG detecting liver SOL was 93.5% and 100.0%, 93.3% and 94.7 in cyst, hemangioma and hepatoma respectively. False positivity of USG was 6.5%.
4) The incidence rate of hepatoma is presumed to be 8.1 and 3.5 per 100,000 in male nad female, respectively.
@ES Coclusion:
@EN The prevalence of liver SOL in general population by USG screening was presumed to be 1.24%. USG screening and follow up examination might be needed for the detection of benign and malignant ones.
