Characteristics of elastofibroma dorsi on PET/CT imaging with 18F-FDG ☆

Abstract Purpose To assess the characteristics of 18F-FDG uptake in elastofibroma dorsi (EFD). Methods Seventeen patients with EFD were retrospectively studied. Results The mean±S.D. of SUV was 2.29±0.60 (range, 1.2–4.3), and the uptake were Grade 0 in 6, Grade 1 in 12, Grade 2 in 7, and Grade 3 in 1. There is no correlation between lesion volume, SUVmax, and computer tomography value. All EFD lesions showed soft tissue density with low or moderate diffused and homogeneous uptake of 18F-FDG. Conclusions Mild and moderate uptake of 18F-FDG is frequently observed in EFD, which should be known to avoid making wrong diagnosis.
