The hydranencephaly is rare in equine species, which is characterized as a congenital malformation where, by viral infections or obstruction of the carotid artery, there is degeneration of the cerebral hemispheres which become translucent membrane that stores the cerebrospinal fluid together with the increase and bone skull deformation due to large fluid collection. Due to the maternal-fetal disproportion between the pelvis of the mother and the fetal head, usually of fetal origin dystocia occurs in most cases when the fetus is in death is resolved through fetotomy with cutting the skull. Because it is a rare event in the equine species with a limited number of papers on the subject, the purpose of this case report is to describe the macroscopic changes in bone of the skull and its contents of the bilateral hydranencephaly in a hybrid foal, product delivered of a dystocic Quarter Horse mare mated with a donkey, served in the Department of Animal Reproduction at a Veterinary School Hospital belonging to a University of the West of São Paulo.
