Metastatic thyroid cancer. There are multiple supratentorial and infratentorial lesions compatible with metastases. There is slight interval increase in size of several lesions since December 2014. For example, a lesion in the anterior left cingulate gyrus measures up to 5 mm, previously 3 mm and a lesion in the left paracentral lobule measures up to 15 mm, previously 13 mm. There is also slightly increased edema associated with the left paracentral lobule lesion. Other lesions are not significantly changed. There is no evidence of acute infarction. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues appear unchanged. There is a right lens implant.
Stable to slight interval increase in size of multiple intracranial metastases.
