more centrally located tumors. Two subsequent studies have established more specific prognostic factors. Oglivie et al 2 reported the importance of tracheobronchial lymphadenopathy, pulmonary metastasis, and evaluation of tumor size in determining
accuracy of diagnostic imaging in detecting TBLN metastasis is not known. In a study of 14 dogs with primary lung tumors, 6 of which had histologic evidence of TBLN metastasis, radiography did not reveal tracheobronchial lymphadenopathy in any of the dogs
diagnosis. Radiographic findings included tracheobronchial lymphadenopathy (9/21), an alveolar pulmonary pattern (6/21), a pulmonary mass (2/21), a bronchointerstitial pulmonary pattern (3/21), and pleural effusion (1/21). In 3 dogs, thoracic radiographs
silhouette on the ventrodorsal projection ( Figure 2 ). The cardiovascular structures, pulmonary parenchyma, and tracheal diameter are unremarkable. There is no evidence of tracheobronchial lymphadenopathy. There is no conclusive evidence of sternal or
caudal lung lobe along with tracheobronchial lymphadenopathy may be the result of granulomatous disease or primary pulmonary neoplasia with metastasis to the tracheobronchial lymph nodes. Considering the history, the most likely diagnosis is a Pythium
importance of tracheobronchial lymphadenopathy, as noted in the patient of this report, is currently unknown. 1. Vail DM , Thamm DH . Hematopoietic tumors . In: Ettinger SJ , ed. Textbook of veterinary internal medicine . St Louis
,4 Tracheobronchial lymphadenopathy, which is common in dogs with pulmonary histoplasmosis, 5 is not commonly seen in cats. 4 Ultrasonography was helpful in this case because the superficial location of the mass in the right cranial lung lobe allowed visualization
lesions in cases of confirmed tuberculosis. 4 However, the usefulness of radiography depends on the extent of the infection. It can be useful in the appraisal of lung involvement, where the changes are variable and may include tracheobronchial
findings, with other possible differential diagnoses of right atrial mass, pulmonary artery aneurysm, tracheobronchial lymphadenopathy, or left cranial pulmonary mass directly abutting the cardiac silhouette. An echocardiogram was obtained to further
