Background: Neurologic abnormalities may occur in pregnancy as a manif
estation of neurologic or systemic disease. We present an unusual case
of preeclampsia presenting with a sixth nerve lesion. Case: A 33-year
-old woman, gravida 2, presented at 38 weeks' gestation with sixth ner
ve palsy. She was hypertensive and proteinuric, with plasma urea of 24
mg/dl. Labor was induced and hypertension escalated in the early puer
perium, with concomitant worsening diplopia. Blood pressure control an
d resolution of preeclampsia were followed by resolution of the sixth
nerve lesion. There was no evidence of other pathology on extensive in
vestigations. Conclusion: Sixth nerve palsy is an unusual manifestatio
n of preeclampsia.
