Abstract

Renal metastasis from adenoid cystic carcinoma of the head and neck is uncommon. We present 99mTc-MIBI SPECT/CT and FDG PET/CT findings in a case with isolated bilateral renal metastases from adenoid cystic carcinoma of the left maxilla. The metastatic adenoid cystic carcinomas of the kidneys showed photopenia on 99mTc-MIBI SPECT/CT and increased FDG uptake on FDG PET/CT mimicking primary renal cell carcinoma.
