Conservative management of a pituitary tumor during pregnancy following induction of ovulation with gonadotropins.
Ovulation induced with human menopausal gonadotropin-human chorionic gonadotropin in a 27-year-old woman who had been amenorrheic for 7 years resulted in pregnancy. Although pretreatment neurologic evaluation was normal, significant loss of vision was found at 30 weeks' gestation, and a skull x-ray revealed enlargement and erosion of the sella turcica. As an attempt to delay surgery, 12 mg of dexamethasone daily arrested further visual deterioration, and the pregnancy continued uneventful for 36 weeks, when triplets were born. Five days after delivery the visual fields were normal. Trans-sphenoidal resection of a prolactin-secreting chromophobe adenoma of the pituitary was carried out 6 months later. It is suggested that when disturbance in visual perception due to a pituitary tumor occurs during pregnancy, a course of high-dose corticosteroids with frequent monitoring of visual fields and acuity might be tried before surgical intervention. Although further rapid deterioration in vision may dictate immediate surgical decompression, conservative management may result in stabilization, allowing the patient to carry the pregnancy to term and obviating the need for emergency surgery.
