Abstract

Objective: This study was undertaken to characterize the neuroimaging findings of cerebral edema associated with eclamptic seizures by use of diffusion-weighted magnetic resonance imaging (MRI). Study design: During the 3-year period ending March 2002, 27 nulliparous women with eclampsia were evaluated with diffusion-weighted MRI and apparent diffusion coefficient mapping. Those with findings of restricted diffusion suggestive of cytotoxic edema underwent neuroimaging again 6 weeks post partum. Results: All but 2 of these 27 women (93%) had reversible vasogenic edema. Six were also found to have areas of cytotoxic edema consistent with cerebral infarction. Five of these 6 women had persistent imaging findings of infarction when studied post partum, however, without clinical neurologic deficits. Conclusion: The spectrum of cerebral lesions in eclampsia as seen with MRI varies from initially reversible areas of vasogenic edema that may progress to cytotoxic edema and infarction in up to a fourth of women.
