Central Nervous System Lymphomas: Clinical and Magnetic Resonance Imaging Findings
Öz
Abstract: Central nervous lymphoma (CNS) is classifed into two sub-types: primary CNS lymphoma and secondary CNS involvement by systemic lymphoma. We aimed to evaluate clinical and magnetic resonance imaging (MRI) features of CNS lymphomas with literature. We retrospectively analyzed the clinical and MR findings of patients with the diagnosis of CNS lymphoma from December 2011 to June 2017. We documented demographic characteristics, lymphoma subtypes, immune status, serum lactat dehidrogenase levels, clinical and MRI findings. We evaluated the number, localization, signal characteristics, diffusion properties, enhancement pattern, presence of hemorrhage and presence of butterfly pattern on MRI. In this study twenty-three patients (male /female: 9/14; mean age: 54±18.years,; age range: 15-81 years) were included and classified as primary (n=3,13%) and secondary (n=20, 87%) CNS lymphoma group. All cases diagnosed as non-Hodgkin lymphoma (NHL) and diffuse large B-cell lymphoma was the most common subtype (65.2 %). The most common symptoms were headache and weakness. The CNS involvement of lymphomas were mostly located in brain parenchyma (56.5%) and leptomeninges (47.8%) All primary CNS lymphoma cases had parenchymal lesion and secondary CNS lymphomas tend to occur in leptomeninges (55%). In all cases 13 patients had 33 parenchymal lesions. The most common location is supratentorial (87.9%), with the most common site cerebral white matter (57.6%). In primary CNS lymphoma group all lesions (n=6) were hypointense on T1 weighted images (WI), heterogeneous hyperintense on T2WI and restricted diffusion on DWI but majority enhancement pattern was homogeneous nodular (83%). In Secondary CNS lymphoma group, lesions (n=27) were mostly hypointense (74.1%) on T1WI, hyperintense (51.9%) on T2WI, restricted diffusion on DWI (96.3%) and homogeneous nodular enhancement (55.6%). Knowledge of the clinical and radiologic features of CNS lymphomas is important in diagnosis, prognosis, assessment of treatment response and survival.
