Recurrent somatic fusions of the two genes, NGFI-A–binding protein 2 (NAB2) and STAT6, located at chromosomal region 12q13, have been identified in<unk> s. This PA chest radiograph demonstrates an abnormal contour in the right hilar region, with visualization of the pulmonary vessels through the mass (the hilar overlay sign) indicating its posterior mediastinal location. On resection this was found to be a benign<unk>  of the pleura. This axial CT image with intravenous contrast (same patient as in the above chest radiograph) reveals what appears to be a posterior mediastinal mass, which was surgically removed and found to be a<unk>  of the pleura.
