Multimodality imaging approach for the diagnosis of a left atrial mass

Background: Cardiac masses may be incidentally found or in relation to the clinical presentation. Depending on the complexity of the lesion, a multimodality imaging approach may be necessary for a proper diagnosis. Case Report: We report the case of a 64-year-old male patient who was referred for pre-chemotherapy work-up of a metastatic scrotal melanoma. Echocardiography showed incidental heterogeneous left atrial mass. Further investigation using cardiovascular magnetic resonance imaging, computed tomography angiography, and positron emission tomography confirmed the findings that were consistent with a left atrialmyxoma vascularized by a left circumflex coronary-cameral fistula. Conclusions: When the clinical context may be misleading, assessment of a cardiac mass with a multimodality approach is essential in order to define its exact benign or malignant nature.
