目的探讨生食泥鳅所致肝寄生虫感染特殊的多层螺旋CT表现。资料与方法回顾性分析38例因生食泥鳅致肝寄生虫感染患者的CT表现及临床资料,探讨其相关病理机制。结果生食泥鳅所致肝寄生虫感染主要表现为肝内多发片状低密度,动脉期周边轻度强化,门静脉期持续轻度强化,甚至可呈等密度,边界不清。结论肝寄生虫感染的CT表现有其特征性,多层螺旋CT增强扫描有助于提高其检出率。
Objective To investigate the special multi-slice CT findings of liver parasites caused by raw loach. Materials and Methods Retrospective analysis of CT findings and clinical data of 38 cases of parasitic infections caused by raw loach to explore the related pathological mechanism. Results The infection of liver parasites caused by raw loach mainly manifested as multiple low-density intrahepatic patches, mild enhancement around the arterial phase, mild persistent portal vein phase, and even iso-density with unclear boundary. Conclusion CT manifestations of liver parasitic infection have their own characteristics. Multi-slice spiral CT enhanced scan can help to improve the detection rate.
