Thyroid Cancer

History

37-year-old female with a history of papillary thyroid carcinoma that
no longer is radio sensitive to iodine thyroid scanning.

CT Findings
CT examination of the neck with contrast showed some increased
density to the left of the trachea in the suprastemal notch region
just below the hyoid bone and the thyroid cartilage region.
This likely represents esophagus and other soft tissue since the whole
body I-131 scan was negative. No findings were suspicious for
metastatic disease.

PET Findings
There is evidence of a small focus on increased radiotracer uptake
just to the left of midline in the lower neck. This may represent a residual
focus of carcinoma in the region of the left lobe of the thyroid or
within an adjacent lymph node.
