目的研究肝脏弓形虫感染的CT表现,为其临床诊断提供客观依据。方法对3例经实验室检查证实的弓形虫肝脏感染患者行多层螺旋CT扫描,结合临床分析其CT图像特点。结果3例患者平扫均见肝脏增大,肝内多发、散在分布的片状低密度病灶,边界不清,形态不规则;增强扫描可见病灶无明显强化,无明显占位效应,偶有正常血管穿行于病灶。结论弓形虫肝脏感染者CT表现具有一定特征性,此病的影像学诊断需要紧密结合临床表现及实验室检查。
Objective To study the CT manifestations of Toxoplasma gondii infection and provide an objective basis for its clinical diagnosis. Methods Three patients with Toxoplasma gondii infection confirmed by laboratory tests were examined with multi-slice spiral CT, and their CT features were analyzed clinically. Results All the three patients showed enlarged liver, multiple intrahepatic and scattered patches of low density lesions with unclear boundary and irregular shape. The enhanced scan showed no significant enhancement of lesions, no significant mass effect and occasional normal Blood vessels pass through the lesion. Conclusion Toxoplasma liver infection has some CT features, imaging diagnosis of the disease need to be closely integrated with clinical manifestations and laboratory tests.
