Detection of fetal scalp cysts may pose diagnostic challenges in terms of d ifferentiating between structures whose origin is ectodermal, so presumed b enign, and neuroectodermal, potentially having neurological significance. W e describe the first case of a fetal scalp dermoid cyst to be detected ante natally and discuss the concept of sequested meningoceles which may not hav e neurological consequence but can be associated with other structural abno rmalities.
