Male patient 54 yo takes CXR for heath check at
Surprisingly we found a very enlarged heart shadow which oblitrated ½ lower chest on both PA and lateral chest XR.
On cardiac ultrasonography, the heart is within normal limits, but there are abnormal structures surrounding the heart with hyperechogeneicity.
We decided to do a thoracic CT scan to clarify the problem.
The result of CT scan shows a very large structure of fat density occupied all lower half of the chest and confirmed by surgery and pathology: about 2 kg of fat was removed from lower mediastinum due to mediastinal lipomatosis.
