Liver	Fourteen patients (70%) had multiple liver cysts; of these, one had liver cystic disease requiring liver transplant at age 43 yr old, and another required liver resections at ages 47 and 48 yr old; one patient had a single liver cyst, four patients (20%) did not show evidence of liver cysts, and no data were available in one patient
