[Diagnosis of a calcified intramural mass next to the posterior mitral valve: review of 4 cases]. / Diagnostic d'une masse calcifiée intrapariétale adjacente à la valve mitrale postérieure: à propos de 4 cas.

PURPOSE: 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. PATIENTS AND METHODS: 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. RESULTS: 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. CONCLUSION: 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.
