So this appears to be an incidental finding of a nodule of the thyroid, on a routine cervical spine MRI.

These nodules are relatively common, and the "high T2 signal" suggests that this is a fluid filled cyst within the thyroid.

What usually happens after this is found, is that blood work is obtained to assess thyroid function (TSH). Then the doctor will have a fine needle aspiration biopsy, where a needle is put into this cyst to get sample of cells and fluid to determine the cause of the cyst/nodule.

Often times these are benign. In a small percentage, the pathology will come back with follicular neoplasm, or a possibly malignant condition, and then referral to a surgeon for excision will be done.
