ABSTRACT
OBJECTIVE: Fetal and neonatal ovarian cysts are detected freguently by ultrasonography. Prenatal ovarian cysts have a follicular or luteal origin. Their natural history is a spontaneous involution. Pre- and postnatal changes in the sonographic aspects allow to choose the appropriate therapeutical indications: conservative approach, surgery, or percutaneous aspiration. MATERIALALS AND METHODS: In retrospective review from 1992-2004 authors present 26 patients with ovarian cysts. RESULTS: Fifteen patients were diagnosed by prenatal ultrasonography carried out between 33 and 39 weeks of gestation. Postnatally 14 were observed only and their cysts regressed, 10 with cysts larger than 4 cm, had surgical exploration, 2 patients with cysts between 2 to 4 cm were candidates for percutaneous aspiration. CONCLUSION: 1. The conservative treatment and clinical observation using ultrasonography is recommended when the ovari cystic is 40 mm in diameter. 2. When the ovari cystic is bigger then 40 mm in diameter it is recommended to perform puncture and fluid aspiration from the cystis under ultrasonography control. 3. The surgical intervention was planned when the ovari cystis was heterogenous and has been growing for a few months.
