The authors report five patients with neuro-Behçet's disease. Computed tomography showed low-density lesions with or without mass effect and contrast enhancement. Magnetic resonance imaging revealed scattered areas of high signal intensity on T2-weighted images, and iso or low signal intensity on T1-weighted images with enhancement after gadolinium injection. These lesions affected all the central nervous system structures with predilection to the brain stem, basal brain ganglia, internal capsula, subcortical and deep cerebral white matter. By its availability, computed tomography remains a precious tool for diagnosis and assessment of severity of neurological involvement. Brain magnetic resonance imaging reveals silent lesions on CT, specifies their exact topography, identifies lesional association reminiscent of neuro-Behçet and contributes to the differential diagnosis with multiple sclerosis. CT and MRI permit the follow-up of lesions under treatment and evaluate prognosis.
作者报告了5例神经白塞病患者。计算机断层扫描显示低密度病变，有或无占位效应及强化。磁共振成像显示在T2加权图像上有散在的高信号区，在T1加权图像上为等信号或低信号，注射钆后有强化。这些病变累及所有中枢神经系统结构，以脑干、基底神经节、内囊、皮质下和深部脑白质为著。由于其可及性，计算机断层扫描仍然是诊断和评估神经受累严重程度的宝贵工具。脑磁共振成像可发现CT上的隐匿性病变，明确其确切位置，识别提示神经白塞病的病变关联，并有助于与多发性硬化进行鉴别诊断。CT和MRI可对治疗中的病变进行随访并评估预后。
