Sonographicdetectionof a metastatic lingual lymph node in a patient with tongue cancer.

A 41-year-old male was diagnosed with tongue cancer. Preoperative imaging revealed no metastatic lymph nodes. Intraoperative sonography detected a minute hypoechoic lesion in the sublingual space. A pea-sized mass was found during dissection of that space and histopathology revealed a metastatic lymph node. The lingual lymph node should routinely be evaluated sonographically prior to surgical resection of tongue cancer.
