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.
