There is a large enhancing mass arising from the left kidney. The mass shows central necrotic areas as well as increased vascularity. The mass invades the abdominal wall.
Case Discussion
Renal cell carcinomas (RCC) are primary malignant adenocarcinomas derived from the renal tubular epithelium and are the most common malignant renal tumor. They usually occur in 50-70 year old patients and macroscopic hematuria occurs in 60% of the cases.
On imaging they have a variety of radiographic appearances, from solid and relatively homogeneous to markedly heterogeneous with areas of necrosis, cystic change and hemorrhage.
