Hydranencephaly is a condition that usually arises in mid/late pregnancy when a major reduction of blood supply to the brain results in loss of most of both cerebral hemispheres.
The more primitive parts of the brain (brain stem, thalamus and cerebellum) are preserved so that usually the vital functions of breathing, heart function and temperature regulation are possible.
Sometimes there may be an excessive rate of head growth and it may be appropriate to insert a shunt system for hydrocephalus to prevent the development of a very large head.

 Choroid Plexectomy Reduces Neurosurgical Intervention in Patients with Hydranencephaly - Karger Publishers
Methods: The hospital and office charts of patients with a diagnosis of hydranencephaly were reviewed from the two institutions spanning the career of the senior author.
Conclusion: In our experience, choroid plexectomy in patients with hydranencephaly reduces the incidence of reoperation and readmission, the number of days of hospitalization related to the surgical procedure and the total number of complications in comparison to patients undergoing CSF diversion.
Choroid plexectomy is a viable alternative to CSF diversion in patients with hydranencephaly and a rapidly enlarging head.

 MedPix™ 3527: Hydranencephaly - Medical Image Database and Atlas
Discussion: Hydranencephaly is a disorder in which much of the supratentorial brain is replaced by thin-walled sacs.
Because the vertebrobasilar arterial supply remains intact, structures supplied by the posterior circulation (occipital lobes, inferior temporal lobes, thalami, brainstem and cerebellum) are preserved.
Preservation of the falx cerebri and separation of the thalami, a consequence of hydranencephaly occurring after brain development, distinguish this disorder from holoprosencephaly, a spectrum of disorders resulting from lack of cleavage of the telencephalon and lack of separation of the telencephalon from the diencephalon.
