Abstract

Recently, the space occupying lesions in the liver were well established and recognized by radioiosotope colorscan. In addition, the lesions were easily localized in the supine and the right lateral projections. The findingsof hepatoma, abscess and cyst were seen as filling defects which were similar to the findings of the hepaticmetastases. In this study, we analysis of 70 cases of the hepatic metastases, 80 cases of the hepatoma and 100cases of the liver abscess which were obtained by radiogold color scan and confirmed by a needle biopsy orlaparotomy. Summary of analysis as follows; 1. Primary site in 70 cases of the hepatic metastases. Stomach 30cases(42.8%) Biliary Tract 10 cases (12.3%) Colon 8 cases (11.4%) Lung 6 cases(8.5%) Ovary 6 cases (8.5%) Pancreas3 cases (4.3%) Thyroid 2 cases (3.5%) Breast 2 cases(3.5%) Kidney, Cervis, Esophagus 1 case. 2. Hepatomegaly wereseen in 22 cases (32%) of the hepatic metastases and relatively small in percentage compared with the hepatoma andabscess. 3. Single space occupying lesion were demonstrated in 26 cases (35.7%) of the hepatiac metastases, 55cases (70.2%) of the hepatoma and 72 cases (72%) of the abscess. Two space occupying lesion were in the scan in 10cases (12.3%) of the hepatic metastases, 8 cases (9.5%) of the hepatoma and 10 cases (10%) of the abscess.Multiple space occupying lesions were seen in 15 cases (21.4%) of the hepatic metastases, 1 cases (17.5%) of thehepatoma and 13 cases(13%) of the abscess. Compare with the hepatoma and abscess, the hepatic metastases tend tomore than one space occupying lesions. 4. The appearance and location of the metastatic lesions showed somewhatsignificant. In 26 out of 30 cases (81.6%) of the stomach carcinoma revealed the lesions mostly located in theporta hepatis and right lower lobe of the liver. Multiple and discrete metastastic lesions were usually from thecolon carcinoma. Mottled appearance in the porta hepatis without hepatomegaly were significant in cases of thebiliary tract and pancreatic carcinomas. Most cases of the biliary stone showed hepatomegaly.
