The Values and Limitations of FDG-PET/CT for Diagnosis of Hibernoma

Figure 1

Axial MRI showing a well-circumscribed slightly heterogeneous mass between the gluteus medius and maximus muscles. On both T1-weighted (a) and T2-weighted (b) images, the signal intensity of the tumor appears high relative to skeletal muscle, being suggestive of fat. Diffuse contrast enhancement is evident (c).
