A case report of anomalous systemic arterial supply to normal basal segments of the right lower lobe with lung cancer

Abstract

A 70-year-old man with an abnormal shadow in the S⁸ of the right lung was diagnosed to have pulmonary squamous cell carcinoma by TBLB. Under thoracotomy, an aberrant artery branching from the diaphragm was found feeding the S¹⁰ of the right lower lobe and a right lower lobectomy (ND2a) was performed. In our case, the final diagnosis was made during the surgical operation. Histological examination of the S¹⁰ revealed pulmonary hypertension.
