[Pituitary tumor detected prenatally].

INTRODUCTION: Brain tumors are present in 2.9 per 100,000 newborn. Craniopharyngioma is a benign and slow growing brain tumor, frequently localized in the sellar and suprasellar region. There are few reports of pituitary tumor detected prenatally. CASE REPORT: We report a neonate with a craniopharyngioma detected prenatally as a pituitary tumor. In a 23 year old mother, second gestation, with no important history, was detected a sellar tumor at 31 gestation weeks, the obstetric ultrasound reported a suprasellar tumor of 2 per 3 cm diameter. Pregnancy ended in a vaginal delivery at 39 weeks, and obtained a 3.9 kg female, with cephalic diameter of 37.5 cm, the Apgar score was 8-9 at 1st and 5th minutes. In early neonatal period was scanned and confirmed a 3.2/2.3/2.9 cm suprasellar tumor with calcium deposits. The Paediatric Oncology department suggested a surgery and was realized a craniotomy at 3rd week of age. The surgery allowed to obtain 30% of the tumor and confirmed by histology craniopharyngioma. Patient had favourable evolution and was discharged at 3 months of age.
CONCLUSIONS: We report a neonate in who was detected by prenatal ultrasound the presence of a suprasellar solid tumor, scan and magnetic resonance images in neonatal period defined its size and location and a craniopharyngioma was confirmed by histology. Patient had a satisfactory postsurgical evolution and was discharged at 3 months of age.
