A resected case of pulmonary sequestration (Pryce type I) complicated by primary lung cancer

Abstract

A 77-year-old man complaining of chronic cough was referred to our hospital for further examination of a 35-mm mass in the left S¹⁰ on chest CT. A definite diagnosis of squamous cell carcinoma was made by TBLB, and left lower lobectomy (ND2a-1) was performed. Under thoracotomy, an aberrant artery arising from the descending thoracic aorta was found feeding the S¹⁰ of the left lower lobe, and the diagnosis was pulmonary sequestration (Pryce type I) complicated by lung cancer. Here, we describe a rare case of lung cancer involving pulmonary sequestration (Pryce type I), with reference to the literature.
