BACKGROUND/PURPOSE: Neonates who have @entity43 caused by an @entity42 often lose their ovary because the torsion and @entity1188 occurred antenatally. Because ultrasound scan has been so effective in diagnosing @entity42 in utero, we have a better understanding of their natural history and can select appropriate cases for cyst decompression in utero to prevent torsion. The authors reviewed experience with seven fetuses who had fetal @entity42 . METHODS: During a 26-month period, seven @entity1 were referred for the evaluation of fetal @entity42 . The mean gestational age at presentation was 31.9 +/- 3.6 weeks (+/-SD; range, 27 to 37 weeks). There was no history of maternal risk factors such as @entity6 or fetal risk factors such as @entity1378 or placentomegally. All seven cases involved isolated @entity45 without @entity154 or @entity2008 . Mean initial cyst diameter was 3.4 +/- 1.7 cm (+/-SD; range, 1 to 6.1). Indications used for @entity42 decompression included @entity45 with a diameter > or =4 cm, a cyst "wandering" about the abdomen on serial sonograms, or demonstrating rapid enlargement (>1 cm/wk). RESULTS: All but one cyst progressed in size during observation. @entity55013 (diameter, 2 cm) subsequently regressed spontaneously and another (diameter, 2.1 cm) stabilized during prenatal ultrasound surveillance. One "cyst" observed with a diameter of 3.5 cm proved to be a persistent cloaca. Four fetal @entity42 met criteria for decompression. Because of fetal position, decompression could not be performed in one. One cyst (seen before defining criteria for decompression) with a diameter of 5 cm was observed only and underwent torsion. Two cysts (diameters, 6.1 cm and 4 cm) were decompressed in utero under local anesthesia with ultrasound guidance, of 95 mL and 35 mL, respectively. High cyst fluid @entity1420 (12,041 and 1,990 ng/dL, respectively) and @entity251 (1,298 and 2,900 ng/dL, respectively) confirmed the etiology of the cyst as ovarian. Neither cyst recurred, and postnatal ultrasound scan confirmed resolution. There was no maternal or fetal morbidity or mortality and only the @entity1 observed before development of criteria for decompression lost her ovary because of torsion. CONCLUSIONS: Fetal @entity42 tend to present as isolated unilateral lesions in normal fetuses in the third trimester. Spontaneous regression of fetal @entity42 may occur. @entity55013 , in select cases, may preserve ovaries at risk for torsion.
