[Ruptured nonparasitic liver cyst caused by blunt abdominal trauma]

Three patients with ruptured nonparasitic liver cyst (two with suspected multiple liver cysts and one with polycystic disease) following blunt abdominal trauma were described. Ultrasonographic examinations and computed tomography (CT) scans were useful in evaluating the presence and degree of liver injury, the amount of hemoperitoneum and the need for operative repair. Two patients with intraperitoneal bleeding were treated by transcatheter hepatic arterial embolization and all three patients were successfully managed nonoperatively.
