Neoplasias das meninges em cães: descrição, diagnóstico e tratamento dos meningiomas

Abstract

Meningiomas are extra-axial tumors of the Central Nervous System and represent approximately half of all primary intracranial tumors in dogs. Those tumors mainly affect older dogs and can cause a series of neurological alterations and reduce their life expectancies and quality of life. Large samples have emphasized the importance of theoretical and practical knowledge regarding the modalities and techniques of current diagnoses and treatments. The use of imaging increases the accuracy of the diagnosis of meningiomas, and facilitates the collection of biopsies, radiotherapy, and surgical treatments. The diffusion of hypo-fractioned radiotherapy allows precise treatments and reduces the adverse effects of radiation. In this literature review, the current diagnostic techniques and treatment modalities will be reported, and a brief review related to the epidemiology, classification and pathophysiology of meningiomas will also be presented.
