a Case reportA 34 year old school principal developed virilising symptoms at 35 weeks of gestation in her second pregnancy. Her menses had been regular but mild hirsutism and acne had been present since age 20 years.Her first child had been conceived at age 29, one year after stopping contraception. Mild acne and hirsutism had been noted at 16 weeks of gestation, and became more severe at 30 weeks of gestation, temporally associated with dexamethasone therapy for threatened early labour. Ultrasound scanning at 36 weeks had shown two solid homogeneous masses in the abdomen. The left measured 106 mL and the right 157 mL. She was induced at 37 weeks of gestation following signs of eclampsia and delivered a phenotypically normal male child. Postpartum maternal examination revealed significant hirsutism (Ferriman-Gallwey score 34/48) and cystic acne involving the face, trunk, and upper arms. Pelvic computed tomography was unremarkable postpartum and androgenic hormone measurements were in the normal range: testosterone <1 nmol/L, DHEAS 2.2 Amol/L, androstenedione 3.4 nmol/L, 17-hydroxyprogesterone 0.7 nmol/L. A combined anti-androgen-oestrogen oral contraceptive was prescribed (ethinylestradiol 35 Ag/ cyproterone acetate 2 mg), but was subsequently discontinued. There was spontaneous return of menses and resolution of her acne and hirsutism over the next 12 months.She conceived her second pregnancy aged 34 years and reported acne, hirsutism, lowering of her voice, and significant weight gain from 12 weeks of gestation. She was shaving facial hair twice daily and teaching had been become an embarrassment. Examination revealed significant virilisation with a FG score of 33, clitoromegaly of 2 cm, grade 4 acne on face, chest and back, and a deep voice. Her facial appearance was masculine. She was referred to our unit at 35 weeks for management.Endocrine data from this pregnancy are presented in Table 1, confirming extreme hyperandrogenism. Ultrasound at 34 weeks demonstrated a male fetus and bilateral solid ovarian masses, size not able to be determined due to the presence of the pregnant uterus. A decision was made to proceed with the pregnancy until fetal viability was assured, given the presence of a male fetus and the expectation that the underlying pathology was likely to be benign. By 36 weeks of gestation, maternal symptoms were so marked, however, that labour was induced and she was delivered of a healthy male infant, confirmed to have an XY karyotype.Magnetic resonance imaging two weeks postpartum revealed ovarian enlargement (36 mL bilaterally) but no masses or cysts, and androgen levels normalised within two weeks of delivery. Following a brief period of lactation, a Mirena IUD was inserted and sequential cyproterone was administered in a dose of 100 mg for 10 days per month, with gradual amelioration of her acne and hirsutes in the six months post-delivery. Ultrasound of the pelvis at three months postpartum demonstrated ovaries of normal volume (8 mL bilaterally) with no morphological evidence of polycystic...
