A 68-year-old female with colorectal cancer developed a metachronous isolated fluorodeoxyglucose-avid (FDG-avid) segment 5/6 gallbladder fossa hepatic lesion and was referred for percutaneous ablation. Pre-procedure computed tomography (CT) images demonstrated a distended gallbladder abutting the segment 5/6 hepatic metastasis. In order to perform ablation with clear margins and avoid direct puncture and aspiration of the gallbladder, cholecystokinin was administered intravenously to stimulate gallbladder contraction before hydrodissection. Subsequently, the lesion was ablated successfully with sufficient margins, of greater than 1.0 cm, using microwave with ultrasound and FDG PET/CT guidance. The patient tolerated the procedure very well and was discharged home the next day.
一位 68 岁的女性患有结直肠癌，后来发展出一个异时性孤立的氟脱氧葡萄糖阳性（FDG-avid）的 5/6 段胆囊窝肝转移病灶，并被转介进行经皮消融。术前计算机断层扫描（CT）图像显示胆囊扩张，紧贴 5/6 段肝转移病灶。为了进行有清晰边缘的消融，避免直接穿刺和抽吸胆囊，在水分离前静脉内给予胆囊收缩素刺激胆囊收缩。随后，在超声和 FDG PET/CT 引导下使用微波成功地对病灶进行了消融，边缘大于 1.0 厘米。患者对该过程耐受良好，次日出院回家。
