case_images: A female aged 62 years old was admitted to our institute with soft tissue metastasis of a follicular variant of papillary thyroid carcinoma, which was confirmed by biopsy (Figure 1).
case_images: Radiological findings and histopathological results of the patient. (a) Ovarian tumor. (b) Lung metastases. (c) Follicular thyroid carcinoma arising within a mature cystic teratoma (HE, x200). (d) Follicular variant of papillary thyroid carcinoma (HE, x400).

case_images: Cranial, thoracic, and abdominal computed tomography (CT) showed the 30 x 14 mm, extra-axial brain lesion without invading the right brain parenchyma; lung metastases; an 82 x 75 mm complex left ovarian mass, its content was mainly fluid with a small solid area (Figure 2(a) and (b)). The definitive histopathological examination revealed a follicular thyroid carcinoma arising from mature cystic teratoma (Figure 2(c)). Two weeks later, the patient underwent total thyroidectomy and surgical removal of left supraclavicular soft tissue; the histopathology of the left thyroid nodule and removed soft tissue are a follicular variant of papillary thyroid carcinomas (Figure 2(d)).
