Unicentric

School ager
with cough and fever. CXR PA and lateral (above) shows a right sided chest mass in the posterior mediastinum. Axial CT with contrast of the chest (below) shows a homogeneous mass, of fat density, with a few septations, in the right posterior mediastinum causing some anterior displacement of the right mainstem bronchus.The diagnosis was lipoblastoma in the posterior mediastinum.
