Case report

A 30-year-old woman (G2P1), with noncontributive history, presented at 22 weeks of her pregnancy. Her first trimester ultrasonography and triple test were normal. At 22 weeks an isolated congenital clitoral hypertrophy of the fetus was detected. The fetal kidneys and suprarenal glands were of normal appearance. An amniocentesis was done revealing normal karyotype (46XX). The course of the pregnancy was uneventful and the diagnosis of isolated congenital clitoral hypertrophy, probably as a consequence of a maternal hormonal influence, was confirmed after delivery.
