A 47-year-old female with the limited form of Wegener's granulomatosis had been treated for seven years. She was admitted to our hospital with a chief complaint of exertional dyspnea. On admission her arterial blood PO2 was 58mmHg. Fiberoptic bronchoscopy revealed the marked stenosis of the subglottic region (about 70%). Oral administration of prednisolone did not improve her symptoms. After tracheotomy, the PO2 went up to 88mmHg and her exertional dyspnea disappeared.
This type of lesion has become rather unusual these days after the introduction of immunosuppressant therapy. But in the future it may be seen more frequently as the patients with Wegener's granulomatosis survive longer.
