摘要
目的 探讨Balo病同心圆硬化的MRI特征及其诊断价值。资料与方法 报告 3例Balo病同心圆性硬化患者的MRI表现。其中 2例为活检病理所证实 ,1例经激素治疗后半年行MRI复查。 3例中的 2例行增强MRI扫描。结果 2例T1WI和T2 WI均较好地显示出本病的同心圆结构特征 ,与病理表现相吻合。 1例MRI表现与多发性硬化类似 ,但增强扫描时 ,可见其病灶呈同心圆样索条状强化 ;经激素治疗后 ,病灶缩小且增强扫描无强化表现。结论 Balo病同心圆性硬化的MRI及其增强扫描具有特征性表现 ,可作为本病生前诊断的主要方法 ,并可用于疗效的观察。
Objective To discuss MRI features and diagnosis of Balo's concentric sclerosis, or called periaxial sclerosis.Materials and Methods MRI findings in 3 patients with Balo's disease were retrospectively analyzed. Of 3 cases, the diagnosis was pathologically proved in 2, MRI re examination was accomplished in another case after steroid treatment for six months. Enhanced MRI scanning was done in 2 cases.Results The characteristic concentric structure of the disease was well displayed in 2 cases on both T 1WI and T 2WI, being consistent with pathological results. In one case, MRI signs were similar to that of multiple sclerosis but the lesion presented concentric enhancement on enhanced scans. The lesion decreased in size and showed no enhancement after steroid treatment.Conclusion The concentric sclerosis of Balo's disease displays characteristic signs on both plain and enhanced MRI, which is very useful in making diagnosis during lifetime and in judging therapeutic results.
