A 28-year-old woman developed late post-partum eclampsia. CT scan showed focal cortical hypodensities and diffuse and bilateral hypodensity of the hemispheric white matter. These lesions were hypointense on T1-weighted sequences and hyperintense on T2-weighted sequences. The CT and MRI abnormalities resolved completely within a few weeks. These changes are similar to those which occur with the more common prepartum eclampsia.
