Summary:Clinical signs of congenital hydrocephalus have been detailed in case of 3 calves. Thereafter results of electroencephalographic (EEG) and pneumoencephalographic (PEG) examinations are summarized. By reason of the comparative evaluation of the EEG of affected calves, EEG was also carried out in 3 healthy calves. It has been found that amplitudes of electroencephalograms of animals with hydrocephalus are significantly increased: 50-150 microV, as compared to the 5-10 microV limit values of healthy calves. Waves are slower and less frequent (1-3 Hz) in the affected animals. They are significantly quicker and more frequent (5-20 Hz) in healthy calves. The shape of EEG waves of calves with hydrocephalus is characterized by the so called hypersymmetry. PEG radiograph has also been reported from which it can be well concluded the dilation of cerebral ventricles and imperfect development of brain substances.
