Autosomal Dominant Polycystic Kidney Disease

Autosomal dominant polycystic kidney disease (ADPKD) is inherited in a dominant trait with variable expression. ADPKD presents in late childhood or early adulthood. US appearance may look similar to autosomal RECESSIVE polycystic kidney disease (ARPKD) initially. Macroscopic cysts will develop during the second decade and be indentified by US exam. Hepatic cysts are seen in one third of cases. Cysts can also be seen in multiple other organs. There is an association with intracranial aneurysms in approximately 20% of cases.
