目的 探讨神经梅毒的MR成像特点,提高对神经梅毒MRI表现的认识.方法 收集临床证实的13例神经梅毒患者进行回顾性分析.结果 MRI表现病变部位位于额叶(7例),顶叶(6例),颞叶(1例),基底节区(2例),脑桥(2例),小脑(3例),脊髓(2例),脑萎缩(11例),T1WI呈低信号、T2WI呈高信号.增强后脑膜型神经梅毒呈脑回样强化;脑膜血管性呈点状、片状不强化灶;树胶肿型见结节状不均匀强化,周围有大片不强化的水肿带;脊髓痨型呈片状、条状不强化灶等.结论 神经梅毒的MRI表现多样,早期诊断须综合分析影像学资料、实验室检查.

Objective: To observe the imaging manifestations of neurosyphilis. Methods: Clinical and imaging data of 13 patients with clinically proven neurosyphilis was collected and retrospectively analyzed. Results: Lesions located in frontal lobe (n=7), parietasl lobe (n=6), temporal lobe (n=1), basal ganglia (n=2), the pontine (n=2), cerebellum (n=3) or in chorda spinalis (n=2), as multiple rounded T2 high signal intensity and T1 low signal intensity, with brain atrophy in 11 patients. After injection of Gd-DTPA, gyria-enhancment was detected in meanings neurosyphilis, punctiform and lamellar unenhan...
