RESUMO
Tuberculous lymphadenitis is an uncommon form of extrapulmonary tuberculosis. We report on a case of isolated Cervicomediastinal tuberculous lymphadenitis without parenhimal involvement. A 49-year old woman was hospitalized with a four week history of night sweats and weight loss. Plain chest radiography disclosed mediastinal mass of the right side. Echocardiographic examination revealed a soft tissue mass below the ascending aorta and aortic arch causing moderate narrowing of the right ventricular outflow tract and the main pulmonary artery. Computed tomographic scanning showed soft tissue mass in the middle mediastinum surrounding the great vessels extending posteriorely with moderate compression of trachea. Histological examination of the cervical mass revealed caseating granuloma containing acid-alcohol fast bacillus. Antituberculous chemotherapy was started.
