Imaging and Management of Incidental Renal Lesions

Figure 12

Hemorrhagic cyst. MRI GE T1-weighted (a), TSE T2-weighted (b), contrast-enhanced GE T1-weighted fat-sat (c), and subtracted postcontrastographic (d) image. A large cystic lesion is detectable on the right kidney (arrows), characterized by mild hyperintensity on GE T1-weighted images and inhomogeneous hyperintensity on T2-weighted and on contrast-enhanced GE T1-weighted fat-sat images. On subtracted postcontrastographic image (d) the lesion shows a regular thin wall with mild enhancement. The final histological diagnosis was hemorrhagic cyst. Note also an anterior huge simple cyst (asterisk) in the same kidney.
