Congenital porencephaly with cerebellar hypoplasia in a Holstein calf: a case report

Abstract

We describe the case of a nine-day-old female Holstein calf which had cheiloschisis, a moderate dome-shaped head, ataxia and opisthotonus since birth. No significant findings except the dome-shaped head were observed on survey radiography of the skull. Computed tomography (CT) images showed bilateral lateral ventriculomegaly, cerebellar hypoplasia and a cyst-like lesion communicating with the right lateral ventricle. Post-mortem examination revealed a cerebral defect in the frontoparietal lobe, which communicated with the right lateral ventricle, and cerebellar hypoplasia. CT provided a characteristic finding of porencephaly and was helpful for diagnosing the accompanying anomalies. We suggest that porencephaly should be included as a specific anomaly in the differential diagnosis of congenital brain malformation.
