Meningocele e craniosquise em bezerros no Semiárido Nordestino.

Abstract

This study describes the cases of meningocele and Cranioschisis diagnosed in calves by the Animal Pathology Laboratory of the Federal University of Campina Grande (LPA-UFCG) during the period from January 2000 to December 2014. Clinical, epidemiological data and macroscopic were analyzed. O diagnóstico definitivo foi feito mediante os achados anatomopatológicos. During the period were reviewed 739 records of cattle necropsies, three cases of meningocele with Cranioschisis (0.40%). The disease occurred in one male and two female without definite breed. These malformations were observed soon after birth, but the calves were sent to the HV / UFCG 3, 7 and 17 days of life. In all cases there was a variable size sacculation, covered by skin integrates and floating in the frontal region. After the skin has been removed, herniation of the meninges was found through an opening in the frontal bone, containing a large amount of red liquor. In the first case also had pulmonary choristoma the skin that covered the meningocele, diagnosed by biopsy, but later died and was not necropsied. In the second case it was observed microscopically and hypoplasia prosencephalic also had areas of hemorrhage, mineralization capillaries and presence of corpora amylacea the perivascular space on the ventral part of the telencephalon and caudate nuclei. In the third case injuries were not described in the encephalon. Thus it can be concluded that meningocele with Cranioschisis occurs sporadically in calves in semi-arid northeast, but it was not possible to establish its etiology.
