The latter included pleural effusion, pneumonia, hilar and bronchovascular infiltration, and also pulmonary granuloma.

In his series the findings were those of perihilar and peribronchial infiltration, patchy pneumonia, pleural effusion, empyema, and single granuloma. The diagnosis of pulmonary brucellosis was based on the history and physical findings, blood cultures, and skin, agglutination, and opsonocytophagic tests.
In 1956 Weed and co-workers3 reported three cases of chronic localized pulmonary
