There is marked enlargement of fluid spaces with little if any overlying cerebral parenchyma except for the posterior fossa and para medial location along the falx.

The posterior fossa structures are inferiorly displaced and the fourth ventricle is not well seen. Higher cuts demonstrate marked cerebral destruction of both cerebral hemispheres predominately in the distribution mid cerebral arteries with minimal residual tissue identified both anteriorly and posteriorly. The anterior fontanelle is bulging.
Case Discussion
This case demonstrates typical CT and ultrasound appearances of hydranencephaly, which is in almost all cases not compatible with significant post natal survival.
