Life-threatening liver laceration with arterial hemorrhage complicating percutaneous treatment of hepatic hydatid cyst.

We present a 76-year-old woman known to have a large right hepatic lobe hydatid cyst which recurred twice after surgical excision. CT-guided percutaneous alcohol ablation was conducted to sclerose the cyst, but the procedure was complicated by parenchymal liver laceration and active arterial hemorrhage from a branch of the right hepatic artery. Bleeding was controlled by both endovascular and surgical interventions.
