MR imaging of postpartum cortical blindness

Cortical blindness is an unusual feature of the toxemia of pregnancy syndrome. We present the CT and magnetic resonance (MR) findings in two women who developed postpartum blindness as a manifestation of this condition. Though both CT and MR display reversible edematous changes in the occipital lobes, follow-up MR documents areas of hemorrhagic and nonhemorrhagic infarction where the corresponding CT images are normal.
