Pneumoencéfalo intraventricular associado à área de necrose nasoencefálica em filhote canino: relato de caso

Abstract

Pneumoencephalus is defined as the presence of air in any of the intracranial compartment. Its most frequent causes trauma and cranial surgeries. Clinical signs occur as a result of increased intracranial pressure and vary with location and extent of the lesion. We report a case involving a seven-months-old female Saint Bernard, who suffered cranial trauma caused by a bite to the face at ten days of age, presenting seizures and local soreness since then. A computed tomography scan of the skull revealed a nasocephalic mass with low contrast enhancement, bone lysis, and hypodensity (-940 Hounsfield units) of the lateral and third ventricles, indicating intraventricular pneumocephalus. During surgery, a fragment of the mass was collected for histopathological examination, which demonstrated the presence of multifocal areas of necrosis.
