患者女,42岁,有长期牧区生活史。因头痛、恶心、呕吐4个月,时有癫样发作就诊。有明确肝包虫病病史。行颅脑磁共振平扫及增强扫描,右侧顶部可见两处类圆形T1WI序列等信号,T2WI序列明显低信号影,内可见多个点状稍高信号影,T2-FLAIR序列为明显低信号影,周围可见大片状高信号水肿区,病变边界清楚;增强扫描示病变呈环状强化,最大病灶2.0cm×1.7cm,顶部大脑镰轻度向左侧移位,右侧侧脑室体部受压、变窄,信号如常;外院CT平扫右侧顶叶脑实质内可见两处结节状稍高密度影,其内可见多发点状更高密度影,周围伴大片状低密度水肿,中线结构轻度左侧移位,右侧侧脑室轻度受压。影像学诊断为脑包虫病(脑泡型包虫病)。
Female patient, 42 years old, has a long history of pastoral life. Due to headache, nausea, vomiting 4 months, when epilepsy treatment. A clear history of liver hydatid disease. Two lines of circular T1WI sequences were observed at the top of the right side of the brain. T2WI sequences showed low signal intensity. A few slightly punctate signals were seen inside the T2WI sequence. T2-FLAIR sequences were significantly lower Signal shadow, the surrounding large echogenic edema area can be seen, the lesion boundary clear; enhanced scan lesions showed ring enhancement, the maximum lesion 2.0cm × 1.7cm, the top of the falx slightly shifted to the left, the right ventricle Department of compression, narrowing, the signal is normal; outside the hospital CT scan the parietal right parietal parenchyma can be seen slightly higher density of the shadow, which can be seen in multiple spots more high-density shadow, accompanied by large patches of low-density Edema, mild left shift of the midline structure, mild right ventricular compression. Imaging diagnosis of echinococcosis (bubble echinococcosis).
