[Idiopathic interstitial pneumonia exacerbated by alveolar hemorrhage].

A 60-year-old man, in who idiopathic interstitial pneumonia (IIP) was diagnosed in 1990, was admitted to our hospital in March 1995 with exertional dyspnea, hemosputum and fever. On chest X ray, new infiltrates in the bilateral middle lung fields were seen, in addition to reticulonodular shadows in the bilateral lower lung fields, which had been noted in 1990. Intubation was reformed because of hypoxemia, and bronchoalveolar lavage (BAL) was performed in right B6. The BAL fluid was bloody, and a diagnosis of alveolar hemorrhage was made based on the presence of many hemosiderin-laden macrophages in the fluid. After pulse therapy with methylprednisolone, the hypoxemia and chest X ray findings improved, and he was extubated. Alveolar hemorrhage may be one possible complication leading to an exacerbation of IIP.
