Pulmonary Q&A by Dr. Schiffman
Pericardial fat is fatty tissue that is adjacent to the heart. The heart is centrally located in the chest with a portion extending into the left side of the chest. Therefore, if there is pericardial fat, it is often located in the lower portion fo the chest adjacent to the heart, not really in the lower left lung.
Thank you for your question.
