Computed axial tomography scan demonstration of cerebral edema in eclampsia preceded by blindness.

The presence of cerebral edema in the occipital lobes are demonstrated by computed tomography (CT) in a patient presenting with eclampsia preceded by blindness at 36 weeks' gestation. After delivery by cesarean section, the patient's management included the use of mannitol and dexamethasone (Decadron) to reduce the cerebral edema. The patient's vision returned within 24 hours after delivery. A repeat CT scan confirmed the resolution of the cerebral edema.
