Key result
A rare mitral valve myxoma in a patient with recurrent embolic events was initially misdiagnosed as a thrombus on cardiac MRI but definitively confirmed by surgery and histology.
Highlights the diagnostic challenge of differentiating rare mitral valve myxomas from thrombi using cardiac MRI, emphasizing the definitive role of surgical histology.
MRI may misclassify mitral valve myxomas as thrombi despite embolic events; case reports leave open reliable noninvasive differentiation criteria.
A case of a rare mitral valve myxoma is reported in a 61-year-old gentleman who presented with recurrent embolic events. The mass was initially diagnosed as thrombus on cardiac MRI, but was later confirmed to be myxomatous in origin, at surgery, and histological examination.
