Meningioma in dog: Case report

Abstract

Intracranial neoplasms are among the main causes of brain dysfunction in geriatric dogs, with meningioma being the most commonly diagnosed. It is an extra-axial tumor that arises from one of the three meninges, principally from the arachnoid. They are usually histologically classified as benign, but they may have a malignant biological character due to primary and secondary intracranial changes that may occur. The mean age for appearance is 9 years old and the main clinical sign is the the appearance of epileptic seizures, but other clinical signs may occur depending on the location, extent and rate of growth. The objective of this work was to report a case of intracranial meningioma in the frontal lobe of a six-year-old Belgian Shepherd dog that was treated at the university veterinary clinic at UFNT, with a history of progressive epileptic seizures and that during the evaluation, head press and visual deficits were observed.
