MRI
Bilaterally the kidneys are of a normal size and polarity. There are bilateral, simple peripelvic renal cysts, the left greater than the right. These are easily appreciated on the coronal T2 and coronal 3D sequences. The calyces are cupped rather than clubbed; hence, there is no hydronephrosis, especially on the left. As per ultrasound, there is a left midpole, simple, Bosniak class I, exophytic cyst. There is no nephroureterolithiasis and no pelviureteric junctional (PUJ) obstruction.
The MRI of the renal tracts is otherwise normal.
