title: [A case of Pryce type I intrapulmonary sequestration].
abstract: A twenty-year-old asymptomatic man hospitalized because of a vascular murmur and abnormal shadow in the left lower lung on X-ray film. An aortogram revealed an abnormal artery arising from the descending thoracic aorta and supplying the left basal segment, which had no other pulmonary arteries. Although lung ventilation scintigraphy demonstrated reduced ventilation to the left lower lobe, bronchogram showed an almost normal bronchial tree except that peripheral branches were slightly thin. A clinical diagnosis of Pryce type I intrapulmonary sequestration was made, and left lower lobectomy was performed successfully. We have analyzed 31 cases of Pryce type I intrapulmonary sequestration in Japan. A vascular murmur is often heard, and a chest X-ray usually shows either a mass shadow or increased vascular markings. In most of those cases, an abnormal artery arises from the descending thoracic aorta and it supplies the left basal segment. Because this type of sequestration causes hemoptysis and infections, surgical intervention is indicated.
