Thyroid and neck ultrasound were performed and pathological cervical and supraclavicular lymph nodes of below 13 mm diameter were described. Thorax computer-tomography (CT) scan was negative, and the patient was referred to Fluor-18FDG positron emission computer tomography (PET-CT) scan, which exclusively confirmed left latero-cervical and supraclavicular lymphadenopathy (Figure 1) as indicated by neck ultrasonography, and no distant metastases.
