A Case of Successful Removal of a Foreign Body Located in the Peripheral Airway Using Flexible Bronchoscopy with Virtual Bronchoscopy Navigation.

A case in which a foreign body located in the peripheral airway of the lung was removed by flexible bronchoscopy using a virtual bronchoscopy navigation (VBN) system has been reported. The patient was a 60-year-old man. Chest radiography revealed an incidental foreign body in the left lower lung. Chest computed tomography with 1.0-mm slices was used to create a VBN system and confirm the foreign body in left B9biiαy, which was removed by flexible bronchoscopy. Thus, peripheral foreign bodies can be safely removed using flexible bronchoscopy by creating a VBN system in advance.

Idiopathic Obliterative Bronchiolitis in a Young Woman: A Rare Case of a Transbronchial Lung Biopsy Contributing to the Diagnosis.

Idiopathic obliterative bronchiolitis (OB) is a rare disease that usually requires a surgical lung biopsy. A 25-year-old woman with progressive exertional dyspnea for several months showed a severe mixed restrictive and obstructive pattern on spirometry. Chest computed tomography showed a mosaic pattern, and pulmonary ventilation-perfusion scintigraphy showed a matched defect. The bronchoscopic specimens obtained from both the alveolar and bronchiolar regions of the predicted lesion area contributed to the diagnosis of OB. She had no underlying causes of secondary OB, and she was diagnosed with idiopathic OB. Since lung transplantation was indicated, she was referred to a lung transplantation-certified hospital.
