Endobronchial fungal infection caused by Candida albicans with main bronchus obstruction: a case report
Abstract Endobronchial fungal infection (EBFI) is a rare form of pulmonary fungal infection that especially affects immunocompromised patients. Furthermore, EBFI resulting in obstruction of the main bronchus is extremely rare. With the development of bronchoscopic techniques, rare cases of EBFI have been reported. A 68-year-old female was referred to the Department of Pulmonology for confusion and obtundation. The patient was diagnosed with septic shock due to acute pyelonephritis followed by obstructive EBFI. We performed bronchoscopic biopsy and endobronchial aspiration for culture. Biopsy showed yeast-like fungus and Candida albicans grew in the culture. EBFI has been under-recognized because of difficulties in confirming the diagnosis. Endobronchial ultrasound-guided transbronchial needle aspiration and bronchoscopy are used to improve the diagnosis of thoracic infection, such as tuberculosis. The role of bronchoscopy in the diagnosis of infectious diseases of the trachea or main bronchi is expected to widen in the future.
