Abstract

We report a case of polycythemia vera with chorea in which the brain metabolism and dopamine system were investigated using 2-[18F]fluoro-2-deoxy-d-glucose positron emission tomography (FDG PET) and 99mTc-labeled tropane dopamine transporter (99mTc-TRODAT-1) single photon emission computed tomography (SPECT). Along with normalization of the hematocrit and clinical symptoms after consecutive phlebotomies, the FDG PET scan and 99mTc-TRODAT-1 SPECT images returned towards normal. It is hypothesized that the development of polycythemia chorea is associated with a reversible alteration in the corticobasal ganglia metabolism and disturbed dopaminergic function.
