Abstract:
Hydranencephaly is a condition that is characterized by an absent brain mantle along with the subadjacent white matter, with replacement of the cerebral hemispheres by a thin-walled membranous sac containing CSF. During brain sonograpy in a neonate with hydranencephaly, we have found a brain-in-brain appearance as an unusual sonographic artifact. We report here on this interesting sonographic artifact in a neonate with hydranencephaly, and this artifact was due to multipath reflection artifact of the ultrasound beam/wave, and we explain the underlying physics.
