18F-FDG cerebellum/liver index as a prognostic factor for progression-free survival in diffuse large B-cell lymphoma.

Objective: 18F-FDG PET/CT provides valuable informations regarding the prognosis of DLBCL. The aim of this study is to test a novel index based on cerebellar uptake to predict progression free survival in DLBCL patients.

Methods: Data from patients with de novo DLBCL between January 2011 and December 2018 were retrospectively collected and PFS was determined.

18F-FDG PET/CT in Anti-Leucine-Rich Glioma-Inactivated 1 Antibody Encephalitis: Typical Pattern and Follow-up.

We report the case of a 55-year-old man presenting pseudopsychiatric behavior disorders of subacute-onset. MRI showed a FLAIR (fluid-attenuated inversion recovery) hyperintensity in the left hippocampus. The diagnosis of limbic encephalitis was raised, and the patient was referred for an 18F-FDG PET/CT.

18F-FDG PET/CT in Sporadic Creutzfeldt-Jakob Disease.

We report the case of a 64-year-old man referred for optic ataxia, constructional apraxia, and spatial orientation disorders evolving for 2 months. Benson syndrome (posterior cortical atrophy) was initially suspected. Brain F-FDG PET/CT depicted an asymmetric decreased uptake pattern consistent with Creutzfeldt-Jakob disease.
