COMPUTED TOMOGRAPHIC FINDINGS IN 57 CATS WITH PRIMARY PULMONARY NEOPLASIA

摘要: Primary pulmonary neoplasia is relatively uncommon in cats and generally has a poor prognosis. In this multicenter, retrospective study of 57 with neoplasia, the most frequent presenting signs were anorexia/inappetence (39%) cough (37%). The tumors considered to be incidental findings 9% cats. computed tomographic (CT) images, primary appeared as mass 55 (96%) disseminated lesion without defined two (4%) Most caudal lobes, 28 (49%) right lobe 17 (30%) left lobe. CT features associated included contact visceral pleura (96%), irregular margins (83%), well-defined borders (79%), bronchial compression (74%), gas-containing cavities (63%), foci mineral attenuation (56%), invasion (19%). mean (range) maximal dimension masses was 3.5 cm (1.1-11.5 cm). Additional disease compatible metastasis observed 53% Pleural fluid evident 30% thrombosis 12% histologic diagnoses 47 (82%) adenocarcinomas, six (11%) origin, three (5%) adenosquamous cell carcinomas, one (2%) squamous carcinoma. series, adenocarcinoma predominant tumor type, but shared many less common types. No associations identified between type features. Prevalence suspected intrapulmonary higher than previous radiographic studies lung tumors.
