FIGURE 4.

Follow-up imaging shows the bilateral hilar lymphadenopathy to be 2-fluoro-2-deoxy-d-glucose-avid, in keeping with active sarcoidosis (middle panel). There was no significant uptake in the pulmonary fibrosis, which is likely burnt-out disease. On cardiac magnetic resonance imaging (right panel), there is no right ventricular (RV) enlargement, but there is mild RV insertion site late gadolinium enhancement (block arrows) suggestive of increased shear stress. Also, note the enhancement of the hilar nodes (thin arrows). LV: ventricle.
