Left kidney presented normal cortical thickness and the urethral stent was found to be in place (Figures 1(a) and 1(b)).
Histological findings: spleen angiosarcoma. At low-power field, histological sections revealed a large hemorrhagic areas with fibrin necrosis (H&E, 4x); at the periphery, foci of a solid vascular proliferation were evident (H&E, 10x). Spindle sarcomatoid cells with prominent hyperchromatic large elements characterized this high grade tumor. At high power field, atypical mitosis (arrow) and pseudovascular spaces were compatible with a final diagnosis of angiosarcoma (H&E, 40x).

These mesenchymal cells showed moderate nuclear atypia and occasional mitoses consistent with a neoplastic nature (Figure 2).
