Patient Data

Age: 30
Gender: Male

X-ray shows a large homogeneous, well defined mass projected over the cardiac silhouette. There is no distortion of the cardiac contour or loss of the heart borders. Appearances likely reflect a large posterior mediastinal mass but there is no rib splaying or vertebral abnormality. 



Subsequent CT shows that the mass is in fact an intra-thoracic kidney with the vascular pedicle extending from the abdomen.

Case Discussion

This case highlights one of the more unusual differentials for a posterior mediastinal mass.
