Neurocysticercosis (NCC) is a parasitic infection caused by , the metacestode of pork tapeworm (). NCC is one of the most common public health problems worldwide. We present a patient harboring a bilobed ring-enhancing lesion with a presumed diagnosis of brain metastasis, who returned to the USA after traveling to an endemic region. The diagnosis of NCC was established based on a characteristic resonance of succinate on proton magnetic resonance spectroscopy. Also, higher mean diffusivity and lower fractional anisotropy along with relative cerebral blood volume were observed from the lesion compared to contralateral normal brain regions. Multiparametric analysis may improve the differential diagnosis of ring-enhancing intracranial lesions such as NCC.
神经囊虫病（NCC）是一种由猪肉绦虫（）的囊尾蚴引起的寄生虫感染。NCC 是全球最常见的公共卫生问题之一。我们介绍了一位患者，他在前往流行地区旅行后返回美国，其脑部存在一个双叶状环形增强病变，疑似脑转移瘤。根据质子磁共振波谱分析中琥珀酸盐的特征共振，诊断为 NCC。此外，与对侧正常脑区相比，病变处的平均扩散系数较高，各向异性分数较低，相对脑血容量较高。多参数分析可能有助于提高环形增强颅内病变（如 NCC）的鉴别诊断能力。
