technetium-tc-99m-bicisate and Alice-in-Wonderland-Syndrome

We present the case of a 53-year-old woman presenting several episodes of body image distortions, ground deformation illusions, and problems assessing distance in the orthostatic position corresponding to the Alice in Wonderland syndrome. No symptoms were reported when sitting or lying down. She had uncontrolled hypertension, hyperglycemia, hypercholesterolemia, and a history of head trauma. Her condition had been diagnosed with left internal carotid artery dissection 2 years earlier. Brain SPECT with 99mTc-ECD performed after i.v. injection of the radiotracer in supine and in standing positions showed hypoperfusion in the healthy contralateral frontoparietal operculum (Robin Hood syndrome), deteriorating when standing up.
