Left ventricular apical mass after myocardial infarction-not always a thrombus: a diagnostic dilemma

BMJ Case Rep. 2021 Oct 19;14(10):e245963. doi: 10.1136/bcr-2021-245963.

Abstract

Myxomas arising from the left ventricle (LV) are extremely rare and can be easily mistaken for a thrombus. We report a case of a 35-year-old man who presented with an acute cerebrovascular accident, having had a prior history of an anterior wall myocardial infarction 2 years back with an echocardiographic evaluation showing mild LV systolic dysfunction. His present prothrombotic workup revealed hyperhomocystinaemia and elevated levels of factor VIII. Present echocardiography revealed a mass arising from a scarred LV wall. Considering the possibility of a thrombus, he was initially started on parenteral anticoagulation. Unfortunately, consequent echocardiogram evaluation showed no reduction in size of the LV mass hence surgical removal was done. Histopathological evaluation unveiled the mass to be a myxoma.
