Pregnancy complicated by idiopathic central diabetes insipidus and oligohydramnios

Maternal diabetes insipidus does not usually adversely affect the course of pregnancy. We present a rare case of central diabetes insipidus diagnosed at 31 weeks of gestation with fetal oligohydramnios successfully treated with intranasal desmopressin. To date, only three cases of diabetes insipidus with oligohydramnios have been reported.
