The authors describe a case of metastasis into the left atrium in a 40 years old woman, who had several oncological diseases in anamnesis. She underwent breast ablation for cancer, amputation of the left lower extremity for chondrosarcoma of the knee joint and hysterectomy for leiomyosarcoma. In the last year she was operated on several metastases of leiomyosarcoma in subcutaneous localization and under pleura. In the PET/CT examination, a focus of increased metabolism of glucose was discovered in the left atrium, which was subsequently visualized during echocardiographic examination. The cardiosurgeon asked for examination by magnetic resonance, which confirmed the finding and displayed perfectly morphology and gave more precision about the relation to adjacent structures.
