[Analysis of 4 cases of intralobar pulmonary sequestration].

Four cases with pulmonary sequestration treated in Tottori university hospital between January 1993 and December 1994 were reported. Case 1 was a 63-year-old male who had lung tumor without inflammatory findings. Differential diagnosis from lung cancer was needed, and aortography showed a aberrant artery from descending aorta. Pulmonary partial resection and division of aberrant artery were performed. Case 2 was a 71-year-old female who diagnosed pulmonary sequestration in other hospital 10 years ago. Tumor shadow did not progress compared with the old X-ray film. Because tumor size was remarkably diminished by aspiration of cystic tumor, conservative follow up was continued. Both case 3 and 4 were a 20-year-old man and 16-year-old female who had typical findings of pulmonary sequestration with inflammation and easily detection of aberrant artery by CT or aortography. Resection of sequestrated lung and division of aberrant arteries were performed in both cases. Pulmonary sequestration was the disease which should be always kept in our mind in differential diagnosis from various lung disease.
