IMPRESSION:

  • Extensive perfusion defects involving the left cerebral hemisphere as well as the left cerebellum.

    Differential diagnosis:

    1. Chronic fatigue syndrome *
    2. Large vessel disease
      * While chronic fatigue syndrome usually presents with multiple bilateral perfusion defects, large unilateral abnormalities may sometimes be seen.

      Large vessel disease is unlikely, however, because the defects involve multiple vascular territories and because the ipsilateral cerebellum is involved.
