The aim is to describe the technique of preoperative CT-guided hookwire localization of small, but suspicious, cervical lymph nodes. We present 3 patients who underwent the procedure for nonpalpable cervical nodes detected on PET/CT prior to complete surgical resection of the nodes. The details of the radiological procedure, surgical outcomes, and pathologic results are described. The mean intervention time for preoperative hookwire localization was 9 minutes (range 7-14 minutes). There were no complications. All surgeons felt that the lengths of the surgical skin incision and operative times were reduced because of localization. The pathologic diagnoses were 2 benign nodes and 1 case of metastatic ovarian carcinoma. In conclusion, preoperative CT-guided hookwire localization is a useful technique for guiding surgical excision, especially when cervical nodes are small and deep in location.
目的在于描述术前 CT 引导下钩丝定位术在小而可疑的颈部淋巴结中的应用。我们介绍了 3 例患者，他们在接受完全切除淋巴结之前，因 PET/CT 检测到颈淋巴结触诊阴性而行该手术。本文描述了放射学操作、手术结果和病理结果的详细信息。术前钩丝定位的平均介入时间为 9 分钟（范围 7-14 分钟）。无并发症发生。所有外科医生都认为，由于定位，手术皮肤切口的长度和手术时间都减少了。病理诊断为 2 例良性淋巴结和 1 例转移性卵巢癌。总之，术前 CT 引导下钩丝定位术是一种有用的技术，可用于指导手术切除，特别是当颈部淋巴结小且位置较深时。
