【摘要】 目的探讨肝片吸虫感染所致肝脓肿的CT表现。方法搜集15例肝片吸虫感染患者的临床及CT影像资料,全部病例经平扫及双期增强扫描,分析其CT表现。结果15例均可见类圆形、结节形病灶,9例呈类似胆管扩张样的分支、条片状病灶,病灶密度不均匀,病灶多发形态多样;肝片吸虫感染所形成的肝脓肿无典型的“环征”及“靶征”,脓肿直径≤3.0cm,未见胆管扩张。结论肝片吸虫感染所致肝脓肿的病理变化,在CT上可以有特征性的表现,结合临床及实验室相关检查,确诊肝片吸虫的可靠性将大大提高。更多还原

【Abstract】 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.更多还原
