[Amniocentesis and single choroid plexus cyst. Current status].

Abstract

Management of a patient with a diagnosed choroid plexus cyst (CPC) is probably one of the most difficult of all prenatal diagnostic problems. Similarity between the risk of chromosomopathy due to the appearance of CPC only and the risk of fetal mortality due to amniocentesis (both being about 1/200) is such that an individual approach must be adopted in each case. The couple must be given a full explanation of all the details, which will enable them to finally decide whether a conservative attitude is appropriate or, on the contrary, if a specific diagnosis should be sought by amniocentesis.
