The meningioma is the most common intracranial neoplasm in dogs and cats. Along the years, the Veterinary Medicine has experienced important technological improvements, making it possible the diagnosis of a lot of diseases. Therefore, diseases considered not common in the past, started being diagnosed more frequently, for instance, brain lesions. The objective of this research is to report a case of intracranial meningioma in a Boxer dog that arrived at the Veterinary Hospital of the Federal Rural University of Rio de Janeiro, highlighting its clinical improvement, diagnosis and treatment.
