1. This pictorial essay focusses on atypical MR imaging features of central nervous system lymphoma, to help radiologists to avoid a delay in the final diagnosis 2. Newer advanced imaging techniques (perfusion, spectroscopy or PET) may potentially aid in the differential diagnosis.  

Definition of primary central nervous system lymphoma Review of conventional MR-findings:         -Common and uncommon features Atypical presentation of primary CNS lymphoma:  - angiocentric lymphoma - diffuse leucoencephalopathy - spinal cord lymphoma - meningeal lymphoma Contribution of advanced imaging: perfusion-MR; MR-spectroscopy and PET imaging. Advanced imaging can aid in the early diagnosis of central nervous system lymphoma with atypical features. The high hypermetabolism on FDG-PET , the low cerebral volume on perfusion maps or the intermedium Choline and the high lipids peaks on spectroscopy curves of these lesions are findings that support the suspected clinical diagnosis.
