OBJECTIVE: To determine the antenatal and short-term neonatal outcome of antenatally detected congenital cystic adenomatoid malformation (CCAM). METHODS: A retrospective review was conducted on all women with an antenatal diagnosis of CCAM who attended the Royal Women's Hospital, Melbourne, between January 1995 and December 2005.
