Objective To study CT features of liver abscesses caused by the fasciola hepatica infection , and discuss its pathologic basis.Methods CT images of 15 Patients were collected. All patients underwent both unenhanced and biphasic enhanced CT scanning, then its CT performances were analyzed. Results round and nodular lesions were observed in 15 cases, branching and stripping lesions like dilated bile duct in 9 cases. The density of lesions was inhomogeneous, and the lesions were multifocal and multiform. The liver abscesses caused by the fasciola hepatica infection had no “rim sign” or “target” sign, Liver abscesses were less than 3.0 cm in diameter, and the dilation of the bile duct were not observed. Conclusion Liver absessed caused by the fasciola hepatica infection have characteristic CT features. Combined with clinical examination and laboratory test, the reliability of diagnosis will be considerably increased.
