A 17-year-old male was admitted with hemoptysis. A chest X-ray film and CT showed a cystic lesion with an air fluid level in the left lower lung field. Arteriography did not revealed aberrant artery. On 48 hospital days after conservative treatment, CT demonstrated lung tissue surrounded by abnormal visceral pleura and the bullous lesion decreased to about 3 cm in size. The preoperative diagnosis was intralobar sequestration. At the time of surgery, sequestrated lung tissue which had the same visceral pleura as the left lower lobe was revealed. Although the arterial and venous supply were from S 10, aberrant artery was not found. The sequestrated lung was resected. Our case was considered to be due to abnormal embryonic development of a lung bud and bronchus.
