Detection of an inflammatory myofibroblastic tumor in the testis by FDG-PET/CT; a rare presentation of a rare neoplasm.

FDG-PET/CT in a 73-year-old man revealed incidental FDG accumulation in the left testicle which was eventually diagnosed as an inflammatory myofibroblastic tumor (IMT): a rare localization of a rare tumor. Previous reports describe moderate to high FDG uptake in IMT but a localization in the testis on FDG-PET has not been described before. Although IMTs are often benign, they can affect nearby tissues and, in rare cases, spread to distant organs. FDG-PET can be used to guide therapy, with surgery being the preferred treatment, and to detect recurrent disease or to evaluate response to systemic treatment.
