Presentation
Left flank pain.
Patient Data
A 35 x 25 mm partially exophytic low enhancing mass is noted at lateral aspect of left kidney causing adjacent fat stranding. There is no sign of local invasion to adjacent structures. Lymphadenopathy is observed at left para-aortic regions. Several small adjacent stones are seen at left kidney, accompanied by mild hydronephrosis.
Mild irregularity of liver margins, enlarged caudate lobe and splenomegaly, in keeping with cirrhosis.
Extrahepatic bile ducts are dilated and CBD measured 15 mm in caliber, without identifying detectable stone or enhancing mass within CBD.
Case Discussion
Work-up for left flank pain in a known case of cirrhosis shows partially exophytic low enhancing left renal mass. Left nephrectomy performed for the patient and histopathology evaluation confirms clear cell renal cell carcinoma.
