Primary Ewing sarcoma of the kidney mimicking cystic papillary renal cell carcinoma in an older patient: A case report

Figure 3 Immediate post-operative ¹⁸F-fluorodeoxyglucose torso positron emission tomography scan and follow up abdominal computed tomography. A: ¹⁸F-fluorodeoxyglucose (FDG) torso positron emission tomography after right nephrectomy shows mild FDG uptake at operation site, which suggested postoperative changes. No other abnormal FDG uptake was demonstrated; B-D: Abdominal computed tomography (CT), taken 6 months after right nephrectomy, shows local recurrence and peritoneal metastasis; E-G: Abdominal CT scan, taken 8 months after right nephrectomy, shows locally controlled local recurrence result from radiotherapy but more progression of peritoneal metastasis with increased malignant ascites.
