Isolated choroid plexus cysts in the second-trimester fetus: is amniocentesis really indicated?

abstract：:Dilatation of the aortic root, outlined by a periaortic fat layer, was observed in 19 of 25 successive cases of aneurysm of the ascending aorta. In one of these cases the aneurysm was entirely confined to the aortic root. In two other cases the aneurysms could not be detected on standard chest radiographs judged in th...
