首发时间:2008-10-22
摘要:目的 分析微灶型脑转移瘤(nodular metastatic tumor of brain, NMTB)和脑囊虫(bladder worm of brain, BWB)的临床和影像特点,提高两种疾病的诊断与鉴别诊断正确率。材料与方法 回顾性分析经临床及病理确诊为NMTB(n=31)和BWB(n=25)的病例,从临床症状、发病年龄及影像征象(包括病灶分布、数目、平扫及增强特点、灶周水肿、出血、钙化及头节等)比较两者的差异。结果 NMTB与BWB在临床症状、发病年龄、病灶分布、CT/MR影像表现、强化模式及灶周水肿方面有显著差异(P=0.000)。结论 临床结合影像能有效诊断及鉴别诊断NMTB与BWB。

A study of the differential diagnosis between nodular metastatic tumor and bladder worm of brain
Abstract:Objective by analyzing the clinical and imaging features of NMTB and BWB, to distinguish the differences of them. Methods the clinical symptom and CT/MR features with 31 NMTB and 25 BWB by final diagnosis were analyzed retrospectively, the compared substances contained clinical symptoms, ages of cases, location, numbers, size, common CT/MR and amplify characteristics of focuses, additionally the edemas around focuses. Results significant differences of these clinical and imaging features between NMTB and BWB was testified (P=0.000). Conclusion by paying attention to the differences of these clinical and imaging features, we can discriminate NMTB from BWB clearly.
