A 70-year-old man with cerebellar syndromes was clinically diagnosed as paraneoplastic cerebellar degeneration and underwent whole-body 18F-FDG PET/CT imaging for screening primary tumor. Intensely elevated tracer uptake in both cerebellar hemispheres was revealed, whereas no abnormality was found in MRI. Increased tracer uptake and swelling of the left tonsil and a cervical lymph node were found at the same time, suggesting neoplasm in tonsil with lymph node metastasis. Pathological examination demonstrated lymphoepithelial carcinoma of the left tonsil.
