[Changes in MR images in pre-eclampsia and eclampsia].

BACKGROUND

Pre-eclampsia affects 2% of pregnancies. This multisystem disorder is a major cause of maternal, foetal and neonatal mortality and morbidity. Neurological manifestations of eclampsia are headache, nausea, vomiting, cortical blindness and recurrent seizures.

OBJECTIVE

The purpose of this study was to determine whether the neurological symptoms correlate with MR imaging findings.

RESULTS

In a patient with eclamptic seizure and another one with blindness due to pre-eclampsia, the white matter hyperintensities on T (2)-weighted MR and FLAIRsequence images could be demonstrated in the occipital region and in the basal ganglia. Within 3-5 days all neurological symptoms and radiological abnormalities had resolved.

CONCLUSION

These cerebral lesions could be classified as posterior reversible encephalopathy syndrome (PRES) or as reversible leukoencephalopathy syndrome (PLES). Thus, MRI supports differential diagnosis regarding non pregnancy-related cerebral disease and can be helpful for therapy planning in cases of pre-eclampsia.
