肝吸虫病继发肝实质炎症的CT表现

CT manifestations of hepatic parenchymal inflammation secondary to distomatosis hepatis

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 inflammation secondary to distomatosis hepatis.The contents of the study include:the morphology,density,and enhanced features in intrahepatic 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 significantly 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.
