A Case of Bronchiolitis Interstitial Pneumonitis / 대한내과학회지

ABSTRACT

Interstitial lung diseases are diagnosed based on clinical, radiological, and histopathological findings. There are various kinds of interstitial lung diseases involving both the interstitium and bronchioles. Bronchiolitis interstitial pneumonitis (BIP) was recently reported as an independent disease cluster combined with both interstitial pneumonitis and bronchiolitis, which is not classified in a specific category of idiopathic interstitial pneumonia (IIP) by the present classification. In this case report, we introduce a recently experienced patient with BIP. A 68-year-old female visited our hospital with aggravated dyspnea for the past 2 months. Her chest computed tomography scan compared to 6 months ago showed increased reticulonodular lesion and ground glass opacities, suggesting interstitial lung disease. A video-assisted thoracoscopic biopsy from a right lower lobe wedge resection resulted in the diagnosis of BIP. Clinical symptoms, pulmonary lesions, and pulmonary function test results remained stable for 1.5 years after oral glucocorticoid and immunosuppressive therapy.
