Treatment planning of head and neck cancer patients has been assisted in recent years by the development of fine-needle aspiration (FNA) biopsy guided by computed tomography (CT) . A case of lower gingival carcinoma with late cervical metastasis of thyroid cancer showed a mass lesion in the retropharyngeal space. The lesion was suspected of metastasizing the thyroid cancer to Rouviere's node. To verify the metastasis, CT-guided FNA biopsy was performed by means of a retromandibular approach. Cytological diagnosis was negative for metastasis, and the result was not inconsistent with the prognosis. The technique used here allows biopsy of the retropharyngeal node in cases where it may otherwise not be accessible.
