Commonly encountered in the general adult and elderly population, in most cases simple renal cysts are confidently diagnosed on imaging studies and do not require further workup or treatment. However, large or growing renal cysts sometimes cause symptoms or signs such as hypertension, palpable mass, flank or abdominal pain, obstructive uropathy, and hematuria, which may indicate the need for minimally invasive percutaneous or laparoscopic treatment. Furthermore, severe complications such as cystic hemorrhage, rupture, or superinfection may occur, particularly in patients with polycystic renal disorders, either hereditary (namely adult polycystic kidney diseases) or acquired in chronic renal failure. This pictorial essay reviews and discusses the cross-sectional imaging appearances of symptomatic and complicated sporadic, hereditary, and acquired renal cysts. Early cross-sectional imaging with multidetector computed tomography or magnetic resonance imaging or both, including contrast enhancement unless contraindicated by renal dysfunction, is warranted to investigate clinical and laboratory signs suggesting retroperitoneal hemorrhage or infection in patients with pre-existent renal cysts, particularly if large, multiple, or hereditary.
