Metastatic liposarcoma of the thyroid gland is exceptionally rare. A case of pleomorphic liposarcoma, which manifested as a soft tissue lump in the neck, is described in a 30-year-old woman. Fine needle aspiration cytology permitted prompt diagnosis. The ultrasound and CT appearance of this type of thyroid metastasis is described which has not been previously reported in the literature.
