Ultrasonography-guided percutaneous radiofrequency ablation for treatment of a huge symptomatic hepatic cavernous hemangioma.

Hepatic cavernous hemangioma is the most common benign tumor of the liver. Appropriate management of this tumor remains a controversial topic. We have accumulated a number of cases with successful management of local hepatic tumors. Here we report a case where we performed an ultrasound-guided percutaneous radiofrequency ablation for the treatment of a symptomatic hemangioma. A 36-year-old female patient visited Kyungpook National University Hospital because of persistent right upper abdominal pain caused by an enlarging hemangioma. After two sessions of radiofrequency ablation, the hemangioma was significantly reduced in size. After 36 months, a follow-up abdominal CT revealed remarkably diminished necrotic areas of ablated hemangioma. The size of hemangioma was decreased to almost one third of the original longitudinal diameter. The patient remains asymptomatic in regards to the hemangioma.
