Etiology/Pathophysiology:
Multiple cysts of variable size with areas of intervening normal
functioning renal parenchyma. Over time the cysts, which don't
communicate with renal tubules or collecting structures, keep
enlarging and continue to compress and therefore compromise the
functioning renal parenchyma.
Pathology:
Not applicable
Imaging Findings:
Ultrasound and IVP shows bilateral enlarged kidneys composed of
multiple large cysts of variable sizes. Forty percent have hepatic
cysts, without hepatic fibrosis. Cysts are also seen in the pancreas,
spleen, gonads, and lungs. Intracranial aneurysms are seen in 10%.
