CXR and CT of inflammatory myofibroblastic tumor in the chest
CXR AP shows a round opacity laterally in the right lung (above left) which projects in the middle of the chest over the trachea on the lateral (above right). Axial CT without contrast of the chest (below) shows the opacity to be a solid mass without calcification next to the pleura.

The diagnosis was inflammatory myofibroblastic tumor.
