Our article reports a case of a 35-year-old man with cardiac mass, who underwent a wide range of imaging methods, including cardiac magnetic resonance imaging (MRI) and positron emission tomography/computed tomography (PET/CT). Contrast-enhanced MRI images revealed “sun ray” pattern in the mass. Final histopathological diagnosis of angiosarcoma was confirmed during autopsy. To our knowledge, our case is the second direct observation of this MRI diagnostic pattern and the first one that allows a comparison with PET/CT findings.
・造影CTで動脈相で辺縁濃染、後期で求心性に増強域拡大・増強効果↑。時に動脈相から不均一濃染や曲がりくねった血管描出
・心膜腔を病変が充満することあり。この病変は造影MRIで放射状濃染(sun ray appearance)を呈する。
