Case in brief
A 67-year-old man with melanoma underwent FDG PET/CT, which showed FDG-avid curvilinear soft tissue anterior, lateral, and posterior to the left kidney. The structure was identified as Gerota fascia, the fibrous sheath surrounding the kidneys, adrenal glands, and adjacent fat, and was involved by metastatic melanoma. The finding demonstrated the fascia’s appearance when affected by malignancy on FDG PET/CT.
What made this case unusual
Gerota fascia, which is not commonly visualized on FDG PET/CT, appeared as FDG-avid curvilinear soft tissue around the kidney because of metastatic involvement.
Diagnostic / clinical pearl
Recognizing the location and expected appearance of Gerota fascia can help identify it when pathologically involved on FDG PET/CT.
