Contribuição ultrassonográfica para diagnóstico de obstrução intestinal por linfoma em felino – relato de caso

Abstract

Alimentary lymphoma is the most frequent malignant neoplasia in cats from middle age to the elderly, characterized by a lymphoid infiltration, which mainly affects the small intestine. Feline leukemia virus and feline immunodeficiency virus are the predisposing factors most involved in its development. The initial diagnosis is made through abdominal ultrasonography, as it is an efficient and non-invasive method to evaluate the gastrointestinal tract. The prognosis varies from reserved to unfavorable, but with new chemotherapy protocols it has achieved a higher survival and better quality of life. In this article we describe the case of a 13-year-old female of the feline, castrated, undetermined species with history of weight loss, vomiting, loose stools and bilateral alopecia of the ears. Ultrasound examination revealed a mass causing partial obstruction of a portion of the jejunum, which was removed through a surgical procedure and histopathological examination was performed, and the diagnosis of alimentary lymphoma was confirmed.
