Renal tumor in autosomal dominant polycystic kidney disease (ADPKD)

Case contributed by Dr Ammar Haouimi

Presentation

Known case of ADPKD with end-stage renal failure, presented with left flank pain.

Patient Data

Age: 80 years

Enlarged kidneys with multiple well-defined cysts of various size are noted bilaterally. A hypoechoic solid mass with foci of calcification is seen in the left kidney. A blood flow is seen within the mass on color Doppler.

Both kidneys are enlarged with innumerable well-defined cysts of various size (up to 8x7 cm on the right, and 8x5 cm on the left). They display a low signal on T1WI, high signal on T2WI with no restricted diffusion on DWI/ADC. On the left there is a solid mass of mediorenal location measuring 7x6 cm of intermediate signal intensity on T1WI, heterogeneous high signal on T2WI with restricted diffusion on DWI/ADC.

No hepatic, pancreatic or splenic cyst seen.

Case Discussion

MRI features suggestive of a malignant renal tumor in a patient with autosomal dominant polycystic kidney disease (ADPKD)

In ADPKD, there is no increased risk for renal cell carcinoma (RCC) unless the patient is undergoing prolonged dialysis 1.
