Figure 1

A: Axial, coronal and sagittal 99mTc-HMPAO SPECT images of the brain obtained during a facial twitching episode show moderate to severe heterogeneous cerebral hypoperfusion with an apparent focus of increased radiotracer uptake near the midbrain. B: 99mTc-ECD SPECT image of the brain obtained two weeks after (A) during a period free from twitching shows resolution of the area of increased uptake. C: Computer-generated depiction of A-B overlayed onto a co-registered MRI shows the area of increased uptake to lie outside the brain.
