18F-FDOPA PET/CT Findings in a Patient With Primary Cerebral Amyloidoma.

Amino acid PET, including F-FDOPA, is recommended for initial characterization, delineation of tumor extent, and follow-up of gliomas because of its high diagnostic performances. F-FDOPA accumulates inside tumor cells via the L-type amino acid transporter 1 (LAT1) whose expression is increased in gliomas. We report here a case of a histopathologically proven brain amyloidoma that was first addressed for a suspected glioma.

Pretreatment Hemoglobin as an Independent Prognostic Factor in Primary Central Nervous System Lymphomas.

Background: Primary central nervous system lymphoma (PCNSL) is a rare subtype of extranodal lymphoma. Despite established clinical prognostic scoring such as that of the Memorial Sloan Kettering Cancer Center (MSKCC) and the International Extranodal Lymphoma Study Group, outcome prediction needs to be improved. Several studies have indicated an association between changes in hematologic laboratory parameters with patient outcomes in PCNSL.
