title: Prenatal karyotyping of choroid plexus cysts.
abstract: OBJECTIVE
  A retrospective, descriptive study of 50 cases with choroid plexus cysts diagnosed by ultrasonography.
  
  
  METHODS
  All case charts were studied and additional information was collected regarding children born outside Uppsala.
  
  
  RESULTS
  All 50 cases were offered a test for chromosome aberrations, 46 accepted and were tested by chorion villi sampling or amniocentesis. In ten cases additional malformations were found, including one trisomy 13 and one trisomy 18. No relationship was found between the diameter, bilaterality or the complexity of the cyst.
  
  
  CONCLUSIONS
  Fetus with choroid plexus cysts should be examined carefully by ultrasonography. Since the complication risk of invasive diagnostic procedures is very small these patients may be offered a test for chromosomal aberrations.
