A 44-years-old female with a ten-year history of coughing underwent physical examination. Since chest X-ray films showed an abnormal shadow, she was referred to our hospital. Chest X-ray films and CT scanning revealed atelectasis of the right middle lobe and hilar lymph node calcification. Bronchoscopy showed stricture of the middle lobe orifice and discharge of pus. On a diagnosis of pulmonary abscess, the right middle lobe was resected. The right middle lobar bronchus was stenotic at the orifice and dilated peripherally at B4 with retention of pus and calculus. Analysis of the stone component revealed calcium phosphate. Since calcification of the hilar lymph node and bronchial wall and structure of the decalcificated broncholith (silver stain) suggested that intrabronchial perforation of calcified lymph node was considered to be the origin of those signs.
