“…These findings are in accord with the CT finding ofa low density area without enhancement and the renal angiographic finding of a hypovascular area (4,(12)(13)(14)(15)(16)(17). By contrast, renal cell carcinomais usually demonstrated as a high-signal intensity area on T2-weighted images with inhomogenous enhancement by GdDTPAon MRI(1 8), as a high density area with enhancement by iohexol on CT (18) and as a hypervascular area on renal angiography (19). Therefore, MRIin addition to CT scan and renal angiography could be another useful diagnostic procedure in differentiating a JG cell tumor from renal cell carcinoma.…”

“…In the larger clinical collective, the incidence of local recurrence was low (five of 140 patients), and the 5-year survival rate was 84% [1]. The importance of CT in the staging of renal cell carcinoma is generally agreed [4,[13][14][15][16][17]. The value of renal CT in the followup after nephrectomy [18,19] or embolization of renal cell carcinoma [20] is also accepted.…”

Computed tomography (CT) was performed in 28 patients 2 weeks to 120 months after enucleation of renal cell carcinoma. The postoperative defect could be exactly localized in all patients. A wedge-shaped (N = 11) or concave (N = 9) morphology was typical. No dependence between morphology of the defect and localization or size of the tumor or the operative technique was observed. The defects were smaller (1.9 cm) than the original prominent tumors (3.6 cm). Defect size was dependent on the operative technique: closure by suture of the renal capsule in smaller defects or by fat flap in larger ones. Postoperative hematomas or delayed perfusion in the adjacent parenchyma were seen in five patients. Tumor recurrence was correctly diagnosed in one patient.

Diagnosis of renal cell carcinoma (RCC) is established using sonography and confirmation by computed tomography (CT). Due to the widespread use of these imaging techniques for numerous indications, small renal tumors are increasingly detected by chance. As the sensitivity of CT is very high, treatment of RCC is routinely initiated without histological confirmation. Standard therapy of locally confined tumors without evidence of lymph node or hematogenic metastases is nephrectomy. However, the results of tumor excision equal those of nephrectomy if tumor size does not exceed 4 cm in diameter. Whereas the prognosis of organ-confined tumors is excellent, no curative treatment for primary metastasized RCC is available to date. Immunotherapy – the only systemic treatment modality with clinically relevant response rates – has so far failed to effect a survival advantage for the patient. Surgery is only potentially curative for asychronous metastases occurring more than 2 years after surgery.
