Figure 2. Cerebral blood flow (I−123)-iodoamphetamine single-photon emission computed tomography (SPECT) before and after steroid therapy. Panel (A) was taken in the acute phase of the disease without steroid treatment. Panel (B) was taken after 5 months when his symptoms had already improved. In comparison with Panel (B) retrospectively, Panel (A) suggests extensive cerebral hyperperfusion, including the brainstem and frontal and medial temporal lobes.
