case_images: Chest X-ray (a) posterior anterior (PA) and (b) lateral views show well-defined homogeneous soft tissue opacity within posterior mediastinum, causing erosion of the 4th rib posteriorly, scalloping of the superior margin of the 5th rib and widening of the 4th intercostal space (arrow).

case_images: There was erosion of the 4th rib posteriorly, scalloping of superior margin of 5th rib, and widened fourth intercostal space [Figure 1a and b].
case_images: Contrast enhanced computed tomography (CT) thorax in (a) mediastinal and (b) lung windows show multiloculated cystic lesion in left paravertebral space, causing erosion of pedicle and lamina of the 4th dorsal vertebra, with intraspinal extension (blue arrow). The 4th rib is eroded (red arrow). Lung parenchyma is extrinsically compressed, unremarkable otherwise (black arrow).

case_images: There was erosion of the overlying 4th rib with scalloping of the 5th rib and widened intervening intercostal space [Figures 2 and 3].
case_images: (a) Three dimensional sagittal multiplanar reformation shows posterior mediastinal mass causing destruction of adjoining vertebra (arrow) with intraspinal extension. (b) Volume rendered coronal image shows erosion of the 4th rib (straight arrow) and scalloping of the 5th rib (curved arrow) with widened 4th intercostal space.
