Symptomatic nonparasitic liver cysts.

Based on our experience with four cases of liver cysts and review of the literature, the following conclusions are reached: (1) Diagnosis can be established with routine and special radiologic studies. (2) Laparotomy is indicated for patients with symptoms or uncertain diagnosis. (3) Surgical management should be guided by cyst size, location, and content. (4) Definitive surgical treatment is indicated only for cysts larger than 10 cm.
