ABSTRACT
A 51-year old man with severe acute respiratory failure was referred to our hospital. He presented with cyanotic digits, high fever and dyspnea. The chest radiograph and chest CT scan showed diffuse ground-glass-opacities and reticular shadows in both lung fields. We diagnosed acute interstitial pneumonia. The pulmonary infiltration seen on chest radiograph diminished gradually after pulse methylprednisolone and cyclophosphamide therapy. Later, we screened his sera for antibodies to anti-aminoacyl tRNA synthetase to diagnose anti-aminoacyl tRNA synthetase syndrome because anti-PL-12 antibodies were positive. This case has been followed but no myositis or recurrence of interstitial pneumonia has been recognized.
