目的探讨梅毒的颅脑MRI改变,提高对梅毒MRI表现的认识能力。方法搜集临床与血液学检查证实为梅毒患者,采用1.5 T MR进行颅脑MRI检查,分析其中5例累及颅脑的MRI表现。结果颅脑MR表现伴有多发梗死灶,大小不一,可累及皮层;T1WI呈低信号或等低混杂信号;T2WI呈高信号或等高混杂信号;T1WI增强后可有不规则强化。结论梅毒检查以实验室检查为主;MRI无特异性改变,但可以显示其病变范围,出现影像学高度怀疑的征象对早期发现及诊断该病具有重要意义。
Objective To investigate the changes of brain MRI in syphilis and to improve the understanding of syphilis MRI. Methods The patients with syphilis confirmed by clinical and hematological examination were collected. The brain MRI was performed by 1.5 T MR, and MRI findings of 5 cases were analyzed. Results Cerebral MR manifestations were associated with multiple infarcts, which were different in size and involved the cortex. T1WI showed low signal or low signal, high signal or high signal at T2WI, irregular enhancement after T1WI increased. Conclusions Syphilis examination is mainly based on laboratory tests. MRI has no specific changes, but it can show the extent of the lesions. The signs of high suspicion of imaging are of great significance for the early detection and diagnosis of the disease.
