Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) scan, maximum intensity projection image showing metabolically active right breast mass (block arrow), right axillary nodes (arrow) and in the left lower thorax-the hypermetabolic hibernoma (notched arrow). Unenhanced axial CT image (a) shows a low attenuating, well-defined mass lesion in the left postero-lateral chest wall (arrow). The contrast enhanced CT (b) shows mild homogenous enhancement. FDG PET (c) and fused images (d) show an intensely FDG avid mass

The scan revealed hypermetabolic right breast mass, metastatic right supraclavicular and axillary lymphadenopathy and liver metastases [Figure 1, maximum intensity projection (MIP)]. Apart from this a hypermetabolic (maxSUV 20.9), low-attenuating, well-defined mass lesion was noted in the left postero-lateral chest wall [Figure 1a-d].

The maximum intensity projection image shows the hypermetabolic primary mass in the right neck (arrow); and another hypermetabolic lesion in the medial aspect of upper right thigh (block arrow). Axial enhanced computed tomography (CT) image (a) reveals a well circumscribed mass with heterogeneous enhancement in right gracilis muscle. Intensely fluorodeoxyglucose avid mass is seen in the fused image (b) similar findings in the coronal CT (c) and fused (d) images

Apart from this, a hypermetabolic lesion was seen in the medial aspect of the right thigh [Figure 2, MIP]. The mass was predominantly of fat density (a little higher than subcutaneous fat) and showed prominent branching vessels within [Figure 2a-d].
