Single omental metastasis of renal cell carcinoma after radical nephrectomy: A case report

Figure 1 Kidney dynamic computed tomography. A: Axial view; B: Coronal view. Initial kidney dynamic computed tomography showing an 8.8 cm × 6.1 cm heterogeneously enhancing mass in the upper to mid pole of the left kidney abutting onto the left adrenal gland and pancreas (arrows).

Figure 2 Abdominal computed tomography. A: Axial view; B: Coronal view. Abdominal computed tomography at 6 mo postoperatively showed a 12 mm enhancing nodule at the left lower peritoneum (arrows).

Figure 3 18F-fluorodeoxyglucose positron emission tomography/computed tomography. F-fluorodeoxyglucose positron emission tomography/computed tomography at 6 mo postoperatively showed a hypermetabolic nodule in the left lower peritoneum (arrow).

Figure 4 Histologic outcomes. Gross and microscopic features in this case: A: Gross examination; B: Hematoxylin and eosin (H&E) staining (magnification, × 400). A: Gross finding shows a well-defined pale yellow solid mass in fibroadipose tissue of the abdominal wall; B: Histological finding shows a metastatic clear cell renal cell carcinoma consisting of atypical clear cell nests in fibroadipose tissue (*).
