Cerebellar hypermetabolism in paraneoplastic cerebellar degeneration

J Neurol Neurosurg Psychiatry. 2006 Apr;77(4):525-8. doi: 10.1136/jnnp.2005.075325.

Abstract

A 51 year old man with paraneoplastic cerebellar degeneration from gastric adenocarcinoma showed cerebellar hypermetabolism and increased perfusion on brain FDG-PET scan and SPECT during the acute stage of his illness. The patient underwent subtotal gastrectomy. The intensity of the hypermetabolism had decreased markedly on follow-up FDG-PET 3 months later following two cycles of chemotherapy. We suggest that the cerebellar hypermetabolism may have been due to an acute inflammatory process associated with an immunological reaction.
