Rare intralobar pulmonary sequestration in right middle lobe ; a case report

Abstract

A 38-year-old woman visited our hospital for further examination of infiltration with cystic components seen in the right middle lung field on chest X-ray. CT scan revealed an isolated area contiguous to normal lung tissue. Bronchographic examination showed a defect of the bronchial trees in the right middle lung field and deviation of the upper and middle bronchi. Arteriography did not show an aberrant artery, but the preoperative diagnosis was intralobar pulmonary sequestration. An operation was performed. Part of S⁴ was emphysematous and was supplied by an aberrant artery (3 mm in diameter) from the thoracic aorta.
The operative diagnosis was rare intralobar pulmonary sequestration in the right middle lobe. The right middle lobe was resected.
