title: [Fever and a mediastinal mass--infection or malignancy?].
abstract: A seventyseven-year old woman had a history of osteomyelitis in the 1940s. Now, she was investigated for an antibiotic resistant fever. An unusual infection, an autoimmune disease or a malignancy was suspected. In the CT scan a mediastinal mass was detected and a mediastinoscopy was performed. Histology revealed a granulomatous infection but a tuberculous infection was ruled out. A favourable response to ordinary antibiotics was gained and the diagnosis of tularemia was confirmed by a serologic test.
