Calcified intramural tumors next to the posterior mitral valve leaflet are rare. The purpose of this paper is to review the differential diagnosis of such lesions.
The CT and MR imaging features of 4 patients (2 males, 2 females) aged between 67 and 76 years with calcified mass at the base of the mitral valve annulus on echocardiogram are reviewed.
From a list of potential diagnoses, the two suggested diagnoses include: post-traumatic calcified myocardial hematoma and liquefaction necrosis of mitral annular calcifications. The diagnostic imaging features are reviewed.
Post-traumatic calcified myocardial hematoma and liquefaction necrosis of mitral annular calcifications may be difficult to diagnose but should be recognized bevause they require simple follow-up.
