Hemangioma cavernoso cerebral em cão

Abstract

Cerebral cavernous hemangioma is a neoplasm of vascular origin uncommon in the brain, characterized by vascular channels atypically dilated and surrounded by endothelium without muscular or elastic fibers. Report a case of intracerebral cavernous hemangioma in the right parietal lobe that was diagnosed in a two-year-old female canine. Clinically the animal presented lethargy, bradycardia, hyporexia, ataxia and seizure. Computed tomography was performed and visible hyperdense mass with well defined limits and presence of hypodense halo with mass effect in right parietal lobe, indicating cerebral hemorrhagic area. Macroscopically, there was irregularly nodular, hemorrhagic area, well delimited in the right parietal lobe and in histopathology nodular formation, with moderate cellularity, delimited, unencapsulated and composed of endothelial cells that delimited large vascular spaces filled by erythrocytes. The clinical signs, tomographic findings, macroscopic and mainly histological findings were consistent with cerebral cavernous hemangioma
