| Abstract|| |
Elastofibroma dorsi (EFD) is a relatively rare soft-tissue pseudotumor that arises from mesenchymal tissue. We present a case of 48-year-old woman who underwent 18F fluorodeoxyglucose (FDG) positron emission tomography-computed tomography for initial staging of suspected carcinoma of the left breast. Incidental detection of soft-tissue masses showing moderate FDG uptake was seen in the bilateral infrascapular location characteristic of EFD.

A 48-year-old woman underwent staging 18F fluorodeoxyglucose positron emission tomography-computed tomography (18F FDG PET-CT) for the evaluation of the left breast lesion. PET-CT revealed an FDG avid lesion in the left breast lower outer quadrant [Figure 1]a and [Figure 1]f with few ipsilateral Level I and II lymph nodes showing increased FDG uptake [Figure 1]a and [Figure 1]g. In addition to these findings, maximum intensity projection images of 18F FDG PET-CT showed symmetrical foci of FDG uptake in the bilateral posterolateral chest regions [Figure 1]a black solid arrows]. Axial CT images [Figure 1]b and [Figure 1]d solid white arrows] show soft-tissue masses in the bilateral infrascapular locations which showed moderately increased FDG uptake in the fused PET-CT images [Figure 1]c and [Figure 1]e solid white arrows]. Biopsy from the left breast lesion showed invasive ductal carcinoma.

Elastofibroma is a benign poorly circumscribed soft-tissue lesion classically located in the subscapular region and hence it is named as elastofibroma dorsi (EFD). It can be seen in other rare sites such as olecranon, ischial tuberosity, thighs, and subcutaneous tissue.,, EFDs show diffuse low-to-moderate grade FDG uptake in a 18F FDG PET-CT scan although high FDG uptake can also be seen that may be caused due to high vascularity and abnormal fibroblastic reactive proliferation within the mass.,, The correct diagnosis of this benign entity is essential to avoid any false positive results and unnecessary interventions in patients suffering from malignant conditions.
