BACKGROUND
Abnormality in diffusion-weighted magnetic resonance imaging representing early changes of acute ischemic lesions in human and animal models of focal status epilepticus has been reported to correlate with clinical outcome.
CASE REPORT
We reported a 35 year-old woman with initial status epilepticus, probably related to previous head injury with traumatic intracerebral hemorrhage. The presenting MRI showed reversible hyperintensity lesions on DWI, which is probably corresponding to the epileptogenic lesion. Similar abnormalities in the splenium as a remote effect were demonstrated in this case.
CONCLUSION
The atrophic changes in the splenium and right parietal lobe in the follow-up MRI scans were supposed to correlate with the following neurological sequelae.
背景
据报道，在局灶性癫痫持续状态的人类和动物模型中，代表急性缺血性病变早期变化的扩散加权磁共振成像异常与临床结果相关。
病例报告
我们报告了一名35岁女性，最初患有癫痫持续状态，可能与既往头部外伤伴外伤性脑内出血有关。最初的磁共振成像显示弥散加权成像（DWI）上有可逆性高信号病变，这可能与致痫灶相对应。在该病例中还发现胼胝体作为远隔效应出现了类似异常。
结论
随访磁共振成像扫描中胼胝体和右侧顶叶的萎缩性改变被认为与随后的神经后遗症相关。
