Epithelioid angiosarcoma images. (A) Plain X-radiographs show an osteolytic lesion in the distal femur. (B) This lesion has apparently widened after 1 month. (C) Magnetic resonance imaging shows a lobulated lesion with a low signal on T1-weighted imaging (top) and a heterogeneous signal on T2-weighted imaging (middle), and heterogeneous gadolinium enhancement is observed on T1-weighted imaging (bottom). (D) [18F]-2-fluoro-2-deoxy-D-glucose positron emission tomography reveals a solitary lesion in the distal femur.
