Key result
Multimodality imaging correctly identified a suspected atrial thrombus as caseous calcification of the mitral annulus in a 78-year-old woman, allowing for the discontinuation of warfarin.
Case Report (n=1)
Caseous calcification of the mitral annulus can be misdiagnosed as a thrombus or tumor on TTE, highlighting the importance of multimodality imaging to prevent unnecessary and potentially harmful treatments like anticoagulation.

Single-modality TTE risks misdiagnosing caseous calcification as thrombus; multimodality imaging extends the differential but remains hypothesis-generating.
Pugliatti et al. (2012) conducted a case report in Caseous calcification of the mitral annulus (n=1). Multimodality imaging was evaluated. Multimodality imaging correctly identified a suspected atrial thrombus as caseous calcification of the mitral annulus in a 78-year-old woman, allowing for the discontinuation of warfarin.
