Man 56 yo for a long time being follow up with thyroid nodule, now he detected the palpable mass at right neck, situation at middle SCM .
Ultrasound suspected lymph node with B mode ultrasound ( picture 1,2: thyroid nodule) on right side of the neck.
For ruling out a thyroid cancer, a FNAC was performed the thyroid mass and the result was colloidal goiter.
MRI of the neck also suspected this mass between carotid internal and external artries ( 2 MRI pictures).
For diagnosing this neck mass we did CDI for guiding FNAC, but this mass was very high vasculature and situated between ICA and ECA. (see 2 CDI images of cross section and longitudinal scanning this mass).
What is your proposal for another step of diagnosis?
