Presentation
Painless hematuria
Patient Data
A large soft tissue mass appears to arise from/ involve the lower pole of the left kidney. On color Doppler examination the mass demonstrates extensive internal vascularity. Additionally, an anechoic 2 cm lesion is present in the upper pole, without solid component.
A large heterogeneous mass lesion is seen predominantly involving lower pole of left kidney. The mass shows extensive enhancement during corticomedullary phase, with heterogeneous enhancement during parenchymal phase with cystic and necrotic areas. A tongue of tumor extends into the very lateral aspect of the left renal vein.
Incidental gallstones, calcified liver granuloma, adrenal lesion, right adnexal cyst and vertebral hemangioma are noted.
Case Discussion
This case illustrates typical appearances of a large (pathologically proven) clear cell renal cell carcinoma.
