Patient presenting with breathlessness has a variety of reasons in the middle age. Apart from respiratory, metabolic, cardiac, infectious, cases have been reported in the literature with compression/impression of Left Atrium (LA) by extracardiac structures like the gastrointestinal tract, aorta / intrapericardial , pulmonary and mediastinal structures. Amongst mediastinal compression, no case has been reported to date due to compression by the dorsal spine. We report such a case of compression of LA due to the dorsal spine, secondary to trauma at a young age, and presenting in the middle age with increasing breathlessness.
