Resection of pulmonary metastasis to the azygous lobe from a malignant fibrous histiocytoma.

A 55-year-old man developed a pulmonary metastasis to the azygous lobe from a malignant fibrous histiocytoma of the thigh. The azygous lobe was not identified at the initial resection. A simple technique for the identification and mobilization of the azygous lobe is presented. Preoperative identification of this anatomic variant may assist in resection of parenchymal neoplasms.
