Adrenal glands appear unremarkable bilaterally, with expected positions superior to the kidneys. Right kidney measures 5.5cm. Left kidney measures 4.7 cm. Bilateral mild pelvicalyceal dilatation (AP renal pelvic diameter right 11 mm, left 10 mm with prominence of the calyces) and dilatation of both ureters to the level of the pelvis, left ureteric diameter of 5 mm, right ureteric diameter 5 mm (measured distally).
Well-defined, encapsulated, multiloculated mass posterior to the bladder with no internal vascularity and mobile internal low level echoes suggesting predominately cystic contents. Dimensions 51mm craniocaudal x 34 mm AP x 33mm transverse. This mass appears to be displacing the rectum to the left, and abuts anterior aspect anterior sacrum/coccyx.
Bladder volume approximately 60ml with the bladder seen anterior to and extending superior to the pelvic mass which has mass effect on the inferior aspect of bladder. Small amount of echogenic dependent debris within the bladder.
IMPRESSION
1) Multiloculated cystic presacral mass with displacement of the rectum.
2) Bilateral hydronephrosis and hydroureter. Bladder extends superior to the pelvic mass and the mass appears to compress the inferior aspect of bladder. Low level mobile debris within the bladder.
