OBJECTIVE The aim of this study was to evaluate the CT findings of amebic liver abscesses and its usefulness for treatment. METHODS CT was performed in 51 patients with proved amebic liver abscess. CT studies were made before and after contrast injection. RESULTS Among the 98 abscesses, 66% occurred in the right lobe. 66% of the patients presented a solitary abscess. The diameters were found between 2 cms to 15 cms. The mean was 7 cms. An enhancing wall was present in 84%; the margins were festooned in 75%, smooth in the other cases; internal septations were noted in 57%. High density material within the abscess, before injection of contrast was seen in 50%. 30% of patients had focal intra-hepatic biliary dilatation, 27% right pleural effusion, 23% peri-hepatic fluid collection. One hepatic-colic fistula and one hepato-pulmonary fistula were not suspected on U.S. examination. Percutaneous aspiration was done in 31% of the patients, when the diameter of the abscesses were more than 10 cms or when they were seen in the left lobe or when fever or pain did not disappear after treatment. CONCLUSIONS CT scan may be helpful in diagnosis of amebic liver abscess at an early stage or later when a complication is suspected. CT scan can also help to indicate and safely perform a percutaneous therapeutic aspiration.
