摘　　要：目的　探讨慢性脑血吸虫病的MR影像特点 ,提高MRI对本病的诊断水平。材料与方法　对 12例慢性脑血吸虫病患者进行脑部MR检查 ,分析其MR影像表现。结果　病灶主要位于额叶 (3例 )、顶叶 (2例 )、颞叶 (3例 )、顶枕交界区(4例 ) ,形态为结节状肉芽肿 ,聚集成簇 ,表现为长T1、长T2 信号和显著的增强效应 ,周围有明显水肿。结论　慢性脑血吸虫病MR影像特点是脑实质内多个结节状肉芽肿聚集成簇 ,颅脑MR检查尤其是增强扫描对本病的诊断和鉴别诊断有重要价值。Purpose [WT5”BZ]To explore the characteristic MRI findings of chronic schistosomiasis of brain and improve diagnosis.[WT5”HZ]Materials and methods[WT5”BZ] Twelve patients with chronic schistosoimiasis of brain were examined by means of MRI,and their MRI findings were analyzed.[WT5”HZ]Results[WT5”BZ] Most lesion lay in frontal(3 cases)、parietal(2 cases)、temporal(3 cases) and parieto-occipital lobe(4 cases),and presents as nodular granuloma which is likely to aggregate with notable edema around it.Their MRI findings were T 1WI hypo-intensity,T 2WI hyper-intensity and notable enhancement.[WT5”HZ]Conclusion [WT5”BZ]The characteristic MRI findings of chronic schistosomiastis of brain is multiple nodular granuloma in brain parenchyma.MRI of brain,especially enhanced scans have graeat value for diagnosis and differential diagnosis of such disease.
