目的:探讨肝吸虫病继发肝实质炎症的CT表现,以提高该病的诊断准确率.方法:回顾性分析48例肝吸虫病继发肝实质炎症的CT表现.观察内容包括:肝内病灶和肝门区淋巴结形态、密度、强化特征.结果:肝吸虫病继发肝实质炎症,平扫时呈低或稍低密度;77.1％(37/48)的病灶增强扫描后面积较平扫时明显缩小;89.6％(43/48)的病灶呈"快进慢出型"强化,10.4％(5/48)呈"轻度延迟型"强化;病灶整体呈轻至中度强化.14.6％(7/48)的病灶肝门区淋巴结肿大,CT增强扫描均呈"快进慢出型"明显强化.结论:充分认识肝吸虫病继发肝实质炎症的影像表现特征,有助于该病的诊断与鉴别诊断.%Objective:To study the CT features of hepatic parenchyma inflammation secondary to distomatosis hepatis,and to improve the diagnostic rate. Methods:To retrospectively analyze the CT features of 48 cases of hepatic parenchyma inflamma-tion secondary to distomatosis hepatis. The contents of the study include:the morphology,density,and enhanced features in in-trahepatic lesions and hilar lymph node. Results:The CT non-contrast enhanced scan showed low or slightly low density in hepatic parenchymal inflammation secondary to distomatosis hepatic;77.1％ lesion area was significantly smaller than the plain and low density area;89.6％ lesions showed "fast in and slow out",10.4％ lesions showed "mild delayed". It showed mild to moderate enhancement. 14.6％ hilar lymph node enlargement,CT enhancement showed "fast forward and slow out" which signifi-cantly enhanced. Conclusion:It's helpful for the differential diagnosis of liver diseases to recognize the imaging features of hepatic parenchymal inflammation secondary to distomatosis hepatis.
