Abstract

We report our first experience with the use of contrast-enhanced ultrasonography (CEUS) to differentiate between a complicated hemorrhagic renal cyst and a cystic renal cell carcinoma in a 50-year-old man diagnosed with autosomal dominant polycystic kidney disease undergoing hemodialysis for end-stage renal disease. CEUS could successfully differentiate between a complicated hemorrhagic renal cyst and a cystic renal cell carcinoma, as opposed to computed tomography (CT) or magnetic resonance imaging (MRI), which could not distinguish between the 2 disease conditions. CEUS is comparable diagnostic tool as CT or MRI to distinguish between benign and malignant cystic renal masses.
