Abstract
Parapelvic renal cysts are found in the area of the renal pelvis. They are usually asymptomatic and found incidentally on renal ultrasound; exceptionally, they may result in symptoms such as lumbar pain with lower urinary tract obstruction, haematuria, or infection.
A definitive diagnosis sometimes requires an excretory phase CT scan with contrast medium. Parapelvic cysts can be a part of hereditary polycystic kidney disease.
Moreover, they have been described to occur more frequently in Fabry disease.
