Abstract

 Hydrocephalus is a nervous system disorder characterized by increased intracranial pressure and head enlargement. Increased intracranial pressure is a direct consequence of fluid accumulation in the ventricular system. This condition can affect almost all animal species, including domestic animals such as cattle, sheep, goats, dogs, and cats.
A lamb that was born by caesarean section and had hydrocephalus abnormality was evaluated biometrically and anatomically after dying in the dissection hall of the Faculty of Veterinary Medicine, as well as cerebrospinal fluid culture was evaluated in the department of microbiology and mycology.The results of this study showed that this abnormality did not have a bacterial or fungal cause, so it is very likely that it can be caused by the issue of nutrition and contamination in the feeding of the mother sheep, or a lack of micronutrients, or a viral factor.Cognitive and physical defects can occur as a result of hydrocephalus. The pathophysiology of hydrocephalus is unclear. While the circulation theory is widely accepted as a hypothesis for the development of hydrocephalus, there is a lack of sufficient proof in clinical situations and in experimental settings. However, there is increasing evidence that osmotic gradients are responsible for the water content of brain ventricles, similar to their presence in other water-permeable organs in the body. Therefore, brain disorders that result in excess macromolecules in the ventricular CSF alter the osmotic gradient and lead to hydrocephalus.
