Abstract
OBJECTIVE: To analyze the clinical manifestations, imaging features and pathological diagnosis of patients with primary central nervous system lymphoma. METHODS: The clinical data of 50 patients with primary central nervous system lymphoma admitted in our hospital from February 2016 to February 2008 were retrospectively analyzed. All the patients were examined by routine pathology and immunohistochemical staining. Among them 15 cases were examined by MVD and VEGF, and the other 15 glioma patients were taken as control group. RESULTS: In 50 patients, the disease was chronic, and the main clinical symptoms were numbness, cognitive disorder and disorder of consciousnessetc. Brain CT image of 33 cases (66%) mainly showed slightly higher density; 46 cases (92%) had head enhanced MRI lesions; 38 cases (76%) showed intracranial multiple lesions, 36 cases (72%) showed invasion of supratentorial, and 11 cases showed midline invasion (22%). Pathological diagnosis confirmed 47 cases (94%) with diffuse large B cell lymphoma, the proliferation index of the Ki-67(90%) in 41 case (82%) was higher. CONCLUSION: Primary central nervous system lymphoma is manifested with diffuse large B cell lymphoma as its main type, or with complicated clinical manifestations, lacks of features and certain imaging characteristics, but a few patients are easily pathologically misdiagnosed, therefore the biopsy is necessary for diagnosis of these patients.
