2. Figure 1
Contrast-enhanced CT scan of sagittal view of kidneys in the nephrogenic phase showing bilateral symmetrical infiltration of the perirenal space (black arrows) encasing both kidneys, giving rise to a “hairy kidney” appearance.

3. Figure 2
T2-weighted MRI of the heart using the half-Fourier, single-shot, spin-echo technique showing an isointense right wall thickening and lumen distortion, giving an atrial pseudomass appearance (white arrow) in addition to a pericardial effusion (black arrow).

4. Figure 3
Contrast-enhanced CT scans of the thorax in the (top) lung and (bottom) soft-tissue windows, revealing multiple centrilobular nodules (curved arrows) in both lungs with septal (straight black arrows) and fissural thickening (straight white arrows), as well as diffuse patchy ground-glass changes. There was also mural circumferential thickening of the aorta (narrow black arrow on both scans), commonly referred to as coated aorta.

6. Figure 5
Biopsy specimen from canthal xanthogranulomas showing touton-type multinucleated giant cells (black arrow). There was proliferation of large histiocytes with round-to-oval nuclei and moderate-to-abundant cytoplasm and surrounding fibrosis. Accompanying the histiocytic proliferation was infiltration of small lymphocytes and plasma cells (Diff-Quick stain [Siemens Healthcare Diagnostics; Deerfield, IL]; original ×600).

7. Figure 6
Biopsy of the perinephric mass showing infiltration of foamy lipid-laden histiocytes with round-to-oval nuclei and eosinophilic cytoplasm. Accompanying the histiocytic proliferation was variable infiltration of small lymphocytes and plasma cells (Papanicolaou stain, original ×600).
