摘要
目的探讨脑血吸虫病的影像学特征及诊断意义。方法对26例脑血吸虫病患者的免疫学检查结果、临床及影像学表现进行分析。结果脑血吸虫病患者可出现各种神经系统临床症状和局灶体征,血清血吸虫抗体阳性,头部CT平扫病变部位低密度影,呈"指套样"水肿;增强后病灶呈"团块样"强化;MRI平扫病变部位长T1长T2异常信号;增强后病灶为"结节样"、"泥沙样"或"斑片样"强化。结论结合临床、免疫学检查及特征性影像学表现可确诊脑血吸虫病。
Objective To explore the diagnosis and imaging characteristics of cerebral schistosomiasis. Methods Twenty-six cases of cerebral schistosomiasis were analyzed with the lab data, clinical and imaging manifestation. Results Cerebral schistosomiasis patients had multifarious nervous system symptoms and focal signs. Antibodies against Schistosoma japonicurn were detected in their sera. CT of the cerebrum showed hypodense area in the lesion with the edema of the surrounding tissue; enhancement was noted after injection of contrast medium. MRI imaging revealed high signal on spin-echo Tl-weighted images and low signal on spin-echo T2-weighted sequences. After administration of contrast medium, the whole lesion showed marginal enhancement. Concision Cerebral schistosomiasis could be diagnosed with the clinical characteristics, immunologic tests and specificity of imageology.
