hydranencephaly

[hīdran′ənsef′əlē]
a neurological disorder in which the cerebral hemispheres are lacking although the cerebellum, brainstem, and other central nervous system tissues may be intact. The newborn with hydranencephaly may have normal neurological functions but does not develop, and computed tomographic scans indicate an absence of cerebral tissue. Treatment is supportive. See also anencephaly.

(hī'dran-en-sef'ă-lē)
Complete or nearly complete absence of cerebral hemispheres, which have been replaced by fluid-filled sacs lined by leptomeninges. The cranium and its fossae are normal.

arthrogryposis and hydranencephaly
occurs as a combined congenital defect in epidemic form in calves, lambs and kids. It may be caused by intrauterine viral infection with the Akabane and Aino viruses, by poisoning with fungi on lupins, and by inheritance of a conditioning factor. See also akabane virus disease, aino virus disease.
