Abstract:
CT findings of hepatic abscesses in 80 patients were retrospectively analyzed. The results showed that most of hepatic abscesses tended to be round or oval (62/80, 77.5%) because of higher osmotic pressure within the cavities. All intrahepatic foci appeared as the hypodense area on CT scans, and their CT attenuation values varied with the amount of fibrin, fatty degenerated leukocytes and necrolic sequesters. The enhanced CT scans showed the lesions more clearly than the unenhanced. Rim enhancement in the wall of abscess was the typical finding (62/80, 77.5%). The detection of “target sign” is highly suggestive of abscess formation and diagnosis of abscess is more valid if there is the gas within the cavities. But some of abscesses were hetrogenerous in density and appeared as “cluster sign” which was composed of the numberous small abscesses and may evolule the larger cavities with multisepta. The chest findings companicd with hepatic abscesses are much common (72/80, 90%). It is difficult to diagnose hepatic abscesses when the margin of lesions is poorly defined and not enhanced after contrast. In (general, CT is an effective, tool in diangosis of abscesses(74/80,accuracy 92.5%).
