Axial T2 weighted (a) and T2w fat-suppressed (b) images show a brightly hyperintense
lesion in the right lobe (long arrow) and a mildly hyperintense solid lesion in the
left lobe (short arrow) of the thyroid gland. Axial T2 weighted (c) and T2w
fat-suppressed (d) images at a cranial section show a mildly hyperintense lesion
(thick arrow) in the right cervical muscles abutting the transverse process of the
cervical vertebra. Coronal STIR image (e) depicts the RT thyroid lesion (long thin
arrow) and right cervical soft tissue lesion (thick arrow).

Apart from the thyroid nodules, the patient had a separate swelling in the posterior cervical space of the right side of the neck measuring 4 x 3 x 2.7 cm MRI neck characteristics of this swelling are shown in Figure 1.
STIR sequence shows an irregular mass in the right paravertebral location extending
to the adjacent neural foramina. The mass shows a hyperintense signal suggestive of
active disease (a). Follow-up MRI (b) shows the appearance of a hypointense signal
within this mass s/o fibrosis.

Serial images done at the interval of 3 months showed stable disease. (Figure 2) The patient is currently on sorafenib for more than 12 months and clinically doing well without any disease-related symptoms or sorafenib toxicity.
