Intraperitoneal seeding from hepatocellular carcinoma following percutaneous ethanol ablation therapy.

We present a case of intraperitoneal seeding in a 36-year-old woman with a large primary hepatocellular carcinoma located superfically in the left lobe of the otherwise normal liver. The patient was treated with percutaneous ethanol ablation therapy. Eight months after the treatment computed tomography and ultrasonography (US) revealed an intraperitoneal seeding that was confirmed with US-guided percutaneous biopsy.
