Abstract:
We present an interesting [18F]fluoro-2-deoxyglucose positron emission tomography (FDG-PET) imaging finding in a patient with ocular flutter and cerebellar ataxia as part of anti-Ma 1/2 antibody-mediated paraneoplastic syndrome associated with a testicular seminoma. He had a typical anterior mesial temporal hyperintensity on magnetic resonance imaging (MRI) without gadolinium enhancement. In addition, his FDG-PET images showed increased deep cerebellar and inferior rectus and superior oblique ocular muscles FDG uptake. This case is the first to visualize in vivo the possible underlying neuropathological mechanism of ocular flutter associated with cerebellar nuclei on functional imaging.
