[Bronchiectasis with normal paranasal sinus roentgenogram].

ABSTRACT

Bronchiectasis has come to be considered as a type of sinobronchial syndrome in Japan, but there exist some cases without chronic sinusitis. We studied the clinical features of 14 cases of bronchiectasis with definitely normal paranasal sinus roentgenogram, diagnosed during the past ten years. There were eleven middle-aged women and three men. Ten patients (71%) complained of hemoptysis, one (7%) of dry cough, one (7%) of productive cough, and the two (14%) had no complaint. In seven patients (50%) CT and bronchography showed localized cylindrical bronchiectasis in the right middle lobe and/or left upper lobe lingular division. They were considered to be middle lobe lingular syndrome. Three patients (22%) with localized varicose or cystic bronchiectasis had a history of pneumonia or pertussis in their infancy, so their bronchiectasis were considered secondary to infantile bronchopulmonary disease. Two patients (14%) had diffuse cystic bronchiectasis and were almost asymptomatic. They might be cases congenital bronchiectasis or Williams-Campbell syndrome. Pulmonary function tests were normal in most of the cases and sputum culture revealed no cases of persistent bacterial infection. These clinical features are quite different from those of bronchiectasis reported as sinobronchial syndrome, in which chronic productive cough, poor pulmonary function, persistent bacterial infection, etc. are significant. So we conclude that there are two distinct groups in bronchiectasis.
