gallium-ga-68-dotatate and Fibroma

Sixty six-year-old woman status post ileocecal resection for well-differentiated neuroendocrine tumor in the terminal ileum 7 years ago, who is on octreotide therapy for liver metastases. Ga DOTATATE PET/CT showed soft tissue masses with mildly increased radiotracer uptake in the bilateral subscapular/infrascapular regions. In retrospective image review, these soft tissue masses were first noted 7 years prior and have gradually increased in size over the years. Given the characteristic location and imaging findings, these masses are consistent with benign elastofibroma dorsi instead of metastasis.
