From: Macrofollicular variant of papillary thyroid carcinoma with metastasis to femur
Metastatic macrofollicular thyroid carcinoma to femur. a CT showed the presence of a tumor involving right thyroid lobe with central necrosis that displaced the upper third of the trachea and the vascular structures on the right side of the neck; b and c MRI showed a destructive neoplasm in the diaphysis and epiphysis of the femur; d The neoplasm showed large follicles in more than 50% of the neoplastic follicles; e Immersed in the metastasis of macrofollicular variant papillary thryroid carcinoma, a bone spicule was observed (*); f Follicles were lined by atypical nuclei and some showed pseudoinclusions
