“…Although magnetic resonance imaging (MRI) or threedimensional (3D) US with reconstructed planes may aid the prenatal diagnosis, we believe that a careful and precise twodimensional (2D) US should be encouraged, since it may be satisfactory enough, in most cases, to demonstrate the sign of the connection between the gall bladder and the cyst, like in our case [10][11][12][13][14][15]. Indeed, MRI as well as 3D technology, although can be very useful in many cases, especially those of unfavourable fetal position, are expensive tools, require expert operators and are not readily available in some clinical contexts.…”
