Abstract: We described a patient with symptomatic giant hepatic hemangioma (GHH) treated with laparoscopic guided percutaneous microwave ablation (MWA). A 58 years’ old woman was referred to our hospital who presented with upper abdominal distension and appetite loss for more than 1 year. The medical history included untreated multiple hepatic hemangiomas (HH) that had been detected 13 years ago and hypertension for more than 12 years. Initial laboratory tests revealed D-dimer mild increase and negative tumor markers. Magnetic resonance (MR) imaging demonstrated multiple nodules of different sizes in the liver and the largest lesion was located on the left lobe (longest diameter 12.8 cm), which replaced the whole enlarged left lobe and compressed the gastric body and inferior vena cava. Contrast-enhanced ultrasound (CEUS) and contrast-enhanced MR imaging both showed the typical enhancement pattern of hemangioma and abnormal perfusion was seen in the surrounding liver parenchyma. With the laparoscopy guidance, we performed microwave ablation till the whole tumor was seen atrophy. The total operation duration was 2 hours, with intra-operative blood loss less than 20 ml. The post-operative course was uneventful. The patient was discharged 3 days after the operation. Abdominal distension decreased, appetite improved, blood pressure controlled at normal level after the operation. MR revealed significant volume reduction of the tumor after the operation.
