Presentation
Presented to the ER with new onset tonic clonic seizures 10 days post partum.
Patient Data
Subcortical and deep white matter scatter bilateral hypoattenuation involving predominantly both parietal and occipital lobes and also involving bifrontal deep white matter.
- The corresponding CT areas appear T2 FLAIR hyperintense.
- They do not enhance in post contrast study.
- No diffusion restriction of the areas.
- The arterial and venous system is unremarkable.
Follow up MR imaging after 6 weeks shows complete resolution of the white matter signal changes seen earlier.
Case Discussion
This is an example of a case presenting with new onset seizures post partum. The documentation of disappearance of all neuroparenchymal signal abnormalities in the follow up study confirms the diagnosis of posterior reversible encephalopathy syndrome (PRES).
