[Cerebral hemodynamic changes in eclampsia--case report].

Eclampsia is a rare condition that is peculiar to pregnant and puerperal women, and its pathophysiology still remains unclear. We conducted a 90-day radiological follow-up of a 29-year-old primigravida who developed eclampsia at 41 weeks of gestation. On admission, magnetic resonance imaging (MRI) showed vasogenic edema predominantly in the parietal and occipital lobes; however with in 2 weeks, these lesions had disappeared. Although single-photon emission CT (SPECT) scanning showed hyperperfusion on day 4, hypoperfusion was shown to be in the right occipital lobe on days 11 and 90. These findings reveal the various changes in cerebral vasculature during the acute phase of eclampsia.
