Fig. 4

58-year-old man with sarcomatoid RCC showing small volume of T2LIA. T2-weighted axial image (A) and post-contrast T1-weighted image (B) shows 11.7-cm right kidney mass demonstrating small area T2LIA (arrows; volume of 15.2 mL; 2.5%) and adjacent non-enhancing area (arrowhead), probably representing hemorrhage (*) and/or necrosis. In the covered lung base, a 3.6-cm left lower lobe lung metastasis was noted (not shown). Cytoreductive radical nephrectomy was done after which pathological analysis showed a 11.5-cm clear cell RCC with extensive sarcomatoid differentiation and renal sinus fat invasion. Systemic treatment including sunitinib and gefitinib was started owing to progression of disease at the thoracic and abdominal lymph nodes, chest wall and lungs. Patient died 226 days after surgery. RCC = renal cell carcinoma; T2LIA = T2 low signal intensity area
