Fistula Formation between Right Upper Bronchus and Bronchus Intermedius Caused by Endobronchial Tuberculosis: A Case Report / 결핵및호흡기질환

Endobronchial tuberculosis is defined as a tuberculous infection of the tracheobronchial tree and has a prevalence of up to 50% in active pulmonary tuberculosis cases. The most common complication of endobronchial tuberculosis is bronchial stenosis; benign fistula formation by endobronchial tuberculosis is rare, especially inter-bronchial fistula formation. We reported a rare case of a 73-year-old woman with a fistula between the right upper bronchus and bronchus intermedius. A diagnosis of inter-bronchial fistula caused by endobronchial tuberculosis was based on the results of chest computed tomography scans, bronchoscopy, and microbiological and pathological tests. The patient was treated with anti-tuberculous medication, and her symptoms gradually improved.

A Case of Lipoid Pneumonia Associated with Silicon Oil Injection into Breast / 결핵및호흡기질환

Exogenous lipoid pneumonia occurs rarely in healthy people. In most cases, exogenous lipoid pneumonia is usually caused by aspiration of mineral, vegetable, or animal oil. We report the case of 42-year-old woman, who have experienced lipoid pneumonia after silicon injection into her breast for cosmetic purposes. The patient experienced fever, dyspnea, sputum, and hemoptysis after silicon injection into her breast. Chest computed tomography demonstrated non-segmental distribution of bilateral consolidation in both lung fields. A transbronchial lung biopsy specimen shows foamy microphages in alveolar spaces. Papanicolaous staining of bronchoalveolar lavage fluid showed abundant foamy marcrophages and many neutrophils. With these results, we confirmed lipoid pneumonia was associated with silicon oil injection into breast.
