Abstract:
A 62-year-old man with an indicated chest radiographic abnormality was referred to our hospital for more thorough examinations. Endobronchial ultrasound-guided transbronchial needle aspiration was performed because of a mass at the left hilum. Endobronchial ultrasound images showed scattered high-density spots in a low echoic and mosaic density. The pathological findings revealed pulmonary hamartoma. Subsequently, the mass was resected and comparison of ultrasound findings and pathological findings indicated that the scattered high echoic spots appeared to reflect cartilaginous tissues and bronchial epithelium inside the tumor.
