title: Unusual noninfectious granulomas of the lung.
abstract: Illustrative cases of pulmonary granulomas with angitis and plasma cell granuloma of the lungs are presented. Experimental evidence suggests that the common pathogenesis of these processes is a cell-mediated immune response. Radiographic findings of these entities--nodules or infiltrates, some with cavities--are non-specific. Effective treatment is available for some of these processes. Lung biopsy as early as possible is recommended.
