XXXX : prenatal diagnosis and management.

@entity1 @entity5 @entity1457 @entity397 @entity44
Although @entity44 is a rare and potentially @entity5 , 10 cases were documented during a 5-year period at the University of Toronto Perinatal Complex. Diagnosis was made in the six cases in which prenatal ultrasound examination was performed. One @entity1 with twins elected to terminate the pregnancy at 19 weeks. In three of the cases diagnosed prenatally, serial ultrasound was performed. There was a 75% cesarean section rate. In all cases diagnosed prenatally, the large @entity5 size affected the mode of delivery. In the four cases without prenatal diagnosis, two @entity1 were delivered vaginally, and two were delivered abdominally for obstetric reasons. There was one case of neonatal morbidity where @entity5 vascularity and @entity397 resulted in @entity1457 . All @entity5 were resected and found to be benign. A plan of management is recommended and, with appropriate obstetric and pediatric care, a good outcome can be anticipated in most cases.
