CASE HISTORY
The patient was diagnosed with subglottic stenosis in 2017. Her chief complaint was difficulty breathing. Pulmonary function tests showed an obstructive pattern of FEV1/FVC at 73%; DLCO was also reduced to 70%, thought to be due to anatomic emphysema, but no imaging findings of emphysema.
Her medical and surgical history was significant for osteoarthritis ( Celebrex), hyperlipidemia, degenerative disc disease (cervical, lumbar), hypertension, meningioma, hypothyroidism, cholecystectomy, appendectomy, knee replacement, finger surgery, tonsillectomy, and mastectomy.
