Characteristic analysis and diagnostic value of spiral CT multi-phase enhanced scan for hepatic abscess

Objective To investigate the CT features of hepatic abscess,in order to improve the diagnostic accuracy.Methods The data of 21 cases of liver abscess pathologically or clinically confirmed were retrospectively analyzed,all cases underwent unenhanced and enhanced scans.Results Among the 21 patients,35 lesions,single lesion in 17 cases and multiple lesions in 4 cases,tumor diameters ranged from 1.5-14.7 cm,with an average of 6.5 cm.Left lobe of liver lesions in 9 cases,right lobe of liver lesions in 26 cases,form class round in 21 cases,irregular-shaped in 14 cases.Scan showed low density lesions in the liver,5 lesions with uniform density,30 lesions with uneven density,of which two lesions containing gas.Thirty-one lesions with fuzzy realm,4 lesions with part fuzzy and part clear realm.By multi-phase check,there were 17 cases of typical liver abscess,in which,1 with single ring,13 with double rings,3 with 3 rings,18 cases of atypical liver abscess.Conclusions The recognition of CT features of dynamic enhanced scan can help to improve the diagnostic accuracy.
