Percutaneous radiofrequency ablation of symptomatic giant hepatic cavernous hemangiomas: report of two cases and review of literature.
The presented cases detail percutaneous radiofrequency (RF) ablation of multiple giant hepatic hemangiomas in two patients who presented with right upper-quadrant pain and fullness and chose not to undergo surgical resection. Treatment of two hemangiomas per patient, 7 cm and 6 cm in one and 9 cm and 2 cm in the other, was accomplished in single ablation sessions with 12 and nine cycles, respectively. Patients had durable resolution of symptoms with reduction of lesion size by 68%-82% at a mean follow-up of 13 months. These cases, along with promising results in the current literature, support RF ablation as a safe and effective surgical alternative.
