Figures

Figure 1
Figure 1. CT Images. a) Coronal non-contrast CT demonstrating a peri-renal mass with heterogeneous attenuation. Hounsfield units measured at −73 indicating fat in mass. b) Axial non-contrast CT again demonstrating left perirenal mass with heterogeneous attenuation arising from retroperitoneum. c) Axial PET/CT shows mild increased FDG uptake with SUV (standardized uptake value) measurements of up to 2.8, which could represent malignancy or inflammatory process.
Figure 2
Figure 2. MRI Images. a) Axial MRI, HASTE (T2-weighted) (left) and HASTE with fat-saturation (right) demonstrates the mass. b) Axial MRI, in phase (left) and opposed phase (right), c) Axial MRI, post-contrast subtracted image shows areas of enhancement in mass.
Figure 3
Figure 3. Histopathology. a) Gross: bivalved kidney with well circumscribed tumor near hilum. b) Microscopic, 20x: sclerotic adipose tissue with foci of chronic inflammation (arrow), c) Microscopic, 400x: multivacuolated pseudolipoblasts (arrows).
