title: [A case of systemic lupus erythematodes with hemosputum and pneumothorax probably resulting from pulmonary infarction and pulmonary angitis].
abstract: A 23-year-old man was admitted with fever, bloodysputum and consolidation in the bilateral lower lobes. Pulmonary infarction in the potla lower lobes was suspected because a lung perfusion scan showed a blood flow defect in the same places. Transbronchial biopsy was performed, and pulmonary hemorrhage and pulmonary angitis were demonstrated in the left lower lobe. His fever and bloodsyputum improved after steroid therapy, suggesting that pulmonary angitis may have been responsible for the bloodysputum. Subsequently pneumothorax occurred. In this case pulmonary infarction associated with pulmonary angitis may have been responsible for the pneumothorax.
