Unusual noninfectious granulomas of the lung.
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.
