Case History: A 90-year-old male had a mass on right kidney seen on previous ultrasound that was being followed for growth.The patient had a history of hypertension and smoking.The patient had no other presenting symptoms at the time of the exam. There was an incidental finding of gallstones during this exam.
The patient had no other presenting symptoms at the time of the exam.
Figure 1. Transverse ultrasound image demonstrates the superior pole of the right kidney with the patient in a left lateral decubitus position. There is an isoechoic appearing mass measuring 6.08 cm in width.
Figure 2. Longitudinal ultrasound image taken with the patient in a left lateral decubitus position demonstrates the mid portion of the right kidney. The well-defined renal mass measures 6.15 cm in length and 4.98 cm in the anteroposterior diameter.
Figure 3. Longitudinal ultrasound image of the mid portion of the right kidney shows increased vascularity along the periphery of the renal mass.
Figure 4. Transverse ultrasound image of the superior portion of the right kidney shows increased vascularity along the periphery of the renal mass.
Renal cell carcinoma is the most common primary renal malignancy.
Risk factors of renal cell carcinoma include advanced age, history of smoking, long term dialysis, and certain genetic conditions such as Von Hippel-Lindau disease.
Renal cell carcinoma is most commonly hyperechoic or isoechoic with increased vascularity.
According to the Robson classification of renal cell carcinoma, there are four stages this pathology can be categorized as.
The prognosis and treatment options depend on the stage of the tumor, the patient's age, and the general health of the patient.
