CXR AP and lateral (above) shows an anteromedial soft tissue density in the right cardiophrenic angle obscuring the right heart border. Sagittal US of the chest performed anteriorly and just to the right of the midline (below left) shows liver extending above the level of the diaphragm. Axial CT with contrast of the chest (below right) shows liver in the right cardiophrenic angle just to the right of the heart in the right hemithorax.
The diagnosis was a right-sided Morgagni hernia containing liver.
