AI summary — for doctors, generated from the abstract only
An incidental FDG-avid testicular lesion in a 73-year-old man proved to be an inflammatory myofibroblastic tumor, a previously undescribed location on PET.
What was studied
Case report of incidental testicular FDG uptake on PET/CT diagnosed as inflammatory myofibroblastic tumor.
Key findings
- Incidental FDG accumulation in the left testis
- Diagnosis: inflammatory myofibroblastic tumor
- IMTs show moderate to high FDG uptake; testicular localization not previously described on PET
Clinical relevance
This highlights IMT as a rare differential for FDG-avid testicular lesions; surgery is the preferred treatment.
Who should care
Limitations
Single case report.
Not every FDG-avid testicular lesion is a germ cell tumor or lymphoma.

Abstract
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.
