FIGURE 3. Planar images of head and chest in patient with sarcoidosis treated by steroid therapy with decreasing doses (3 mg/day at time of scintigraphic evaluation). (A) Gallium scintigraphy shows only mildly increased uptake in hilar and mediastinal lymph nodes and in lung. (B) SRS shows high uptake with well-delineated lesions in hilar and mediastinal lymph nodes and in lung and reveals corticomeningeal and skull involvement, which was confirmed after SRS by cerebral MRI.
