What is Hydranencephaly?
A severe congenital condition in which the cerebral hemispheres are largely or completely absent and replaced by a sac filled with cerebrospinal fluid, typically caused by a catastrophic vascular event (occlusion of the internal carotid arteries) during fetal development. The brainstem and cerebellum are usually preserved, allowing the baby to breathe and show basic reflexes, but severe developmental impairment is universal.
