摘要
肝脏嗜酸性肉芽肿是由长期炎症引起肉芽肿形成继而发生。本文分析2008年7月至2012年4月烟台市烟台山医院和烟台市毓璜顶医院收治的2例肝脏非特异性嗜酸性肉芽肿患者的临床资料，并总结其影像学特征。实验室检查均提示患者外周血嗜酸性粒细胞增高，超声检查发现低回声肝脏包块，彩色多普勒检查无血流信号。CT检查示略低密度病灶，边界欠清晰，增强扫描示延迟期不均匀强化，病灶呈网格状改变。1例患者接受MRI检查，T1WI 扫描示病灶呈不规则略高信号，边缘欠清晰，其内见一斑片状低信号；T2WI扫描呈高信号，内见低信号分隔；DWI扫描呈明显高信号。熟悉肝脏非特异性嗜酸性肉芽肿的影像学特征，并结合外周血嗜酸性粒细胞增高，可以帮助临床医师作出正确诊断。
Hepatic eosinophilic granuloma is a rare benign liver lesion, which results from granuloma formation due to chronic inflammation. Two patients were admitted to the Yantaishan Hospital and Yuhuangding Hospital from July 2008 to April 2012, respectively. The results of laboratory examination showed the elevation of peripheral blood eosinophils, and ultrasound examinations revealed lowecho masses in the liver and no blood flow was detected. The results of computed tomography showed hypoattenuation lesions with welldemarcated boundary. After intravenous administration of contrast angent, the lesions demostrated delayed heterogeneous enhancement with internal grid. The results of magnetic resonance imaging of 1 patient showed the lesion had slight hyperintensity to the surrounding liver parenchyma on T1weighted images, and slight high signal with low signal separation strip inside on fatsuppressed T2weighted images. An obvious high signal was detected in diffusion weighted imaging. Familiarity with the imaging characteristics and combination of the elevation of peripheral eosinophil can help surgeons to make a suggestive diagnosis.
