Abstract
Primary cardiac osteosarcoma is a very rare malignancy with nonspecific symptoms, making early diagnosis a challenge. We report the computed tomography and magnetic resonance imaging findings of a primary cardiac osteosarcoma arising from the left atrium and posterior mitral leaflet in a 58-year-old woman with multiple metastases to the brain, skull, clavicle, lung, ribs, liver, lymph nodes, and thyroid gland.
