title: [Multilocular cystic renal cell carcinoma treated with tumor enucleation: a case report].
abstract: We report a 65-year-old man with a multilocular cystic renal cell carcinoma which was found incidentally. Computed tomography (CT) demonstrated a 3.0 cm x 3.0 cm multilocular cystic mass at the upper pole of the left kidney. Dynamic MRI demonstrated that the septic wall of the multilocular cystic mass was enhanced. Renal angiography showed a hypovascular tumor. We diagnosed that the tumor was multilocular cystic renal cell carcinoma with a tumor capsule and performed tumor enucleation. The histopathological examination showed that the cystic and septic wall consisted of renal cell carcinoma, clear cell subtype, grade 1. From the review of the literature, the prognosis of multilocular cystic renal cell carcinoma was good, so we selected nephron sparing surgery for this case.
