| Popis: | Bronchocentric granulomatosis is an unusual pathologic entity that is characterized by a necrotizing granulomatous inflammation surrounding the airways. The diagnosis is usually made retrospectively, after histopathologic examination of an open-lung biopsy or resection of a pulmonary lesion. Although the aetiology has not been fully elucidated, the current pathogenetic mechanism is considered to be an immunologic reaction against endobronchial antigens, since most patients exhibit signs of bronchial asthma, eosinophilia and allergic bronchopulmonary aspergillosis. However, non-asthmatic patients may develop bronchocentric granulomatosis without signs for endobronchial fungal infections, but probably as a consequence of other pulmonary infections. An 80-year-old female patient presented with high fever and bilateral pulmonary infiltrates and nodules. After extensive investigations and open-lung biopsy, the diagnosis bronchocentric granulomatosis was established that was possibly associated with an influenza-A virus infection. Treatment consisted of immunosuppressive drugs (prednisone and cyclophosphamide), which led to complete clinical and radiological recovery. |
