摘要：
Primary intraosseous squamous cell carcinoma (SCC) is an uncommon malignant cancer involving the jaw bones. We herein reported the imaging findings of a primary intraosseous SCC of the mandible in a 47-year-old man. He was diagnosed as cancer of unknown primary in the cervical node. FDG PET/CT revealed a focal hypermetabolic lesion around the tooth root of the right lower molar. MRI showed the lesion had hyperintensity on T2-weighted imaging and significant enhancement on T1-weighted imaging fat saturate images. The final diagnosis of primary intraosseous SCC of mandible was confirmed pathologically. © 2021 Wolters Kluwer Health, Inc. All rights reserved.
