  • Figure 1.
    Figure 1.

    Image findings of the left shoulder in a 48-year-old man suffering from epithelioid angiosarcoma of the scapula. A, B: Plain x-ray radiography shows a large bone destruction of the glenoid appearing as homogenous radiolucent area with no calcification and no reactive bone sclerosis at the margins (arrowheads). C-F: CT-scan allows better assessment of the intraosseous extension (D, E: bone window, arrows) with partial destruction of the articular surface and the anterior border of the glenoid and adjacent scapula. Soft tissue window (C, F: arrows) exhibits the distinctive extraosseous soft tissue component extending to the axilla as well as local lymph node enlargement (C: broken arrow).

    Figure 2.

    MR image findings of the left shoulder in a 48-year-old man suffering from epithelioid angiosarcoma of the scapula. Coronal views are displayed in the upper row, axial views are shown in the lower row. A: T2-weighted inversion recovery sequence. B: T1-weighted spin-echo sequence; C, F: fat-saturated T1 gradient echo sequence; E: diffusion-weighted sequence. A large tumour destruction of the glenoid and the adjacent scapula is seen (arrows). The lesion exhibits a high inhomogeneous signal in diffusion-weighted and T2-weighted sequences (A, E) and a rather homogenously low signal on T1-weighted imaging (B). In contrast-enhanced images (C, F), a strong contrast-enhancement is seen, indicating the vascular origin of the tumour. However, the signal loss, particularly in the centre of the lesion indicates distinctive necrosis.

    Haematoxylin and eosin stain, ×400 magnification. Epithelioid angiosarcoma composed of solid sheets of large, oval or rounded epithelioid cells with amphophilic cytoplasm and very prominent nucleoli (arrows).
