Intra-luminal fibrosarcoma in the cranial vena cava of a dog

Abstract

The present study refers to a male animal from the canine species, of indefinite breed, about 12 years old, that for several days had been presenting edema of the head and cervical region, including the former limbs and sternum region. Clinical examination showed high temperature (39,5 °C ) bilateral purulent nasal discharge, mixed dyspnea, besides inappetence and prostration. Radiographic examination was impaired by the animal's condition at the time; other tests performed gave no Information suggesting a circulatory obstruction near the cranial cava. Necropsy revealed a tumor of about 4x2x2 cm located in the luminal cranial cava vein. Histological examination showed it to be a fibrosarcoma.
