Abstract:Objective To study the clinical imaging features of intracranial lymphoma in order to clarify its diagnosis. Methods A retrospective study of 34 cases of intracranial lymphoma operated in Xuanwu Hospital during 7 years was conducted, and all data were analyzed carefully. Results The duration of the disease ranged from 2 months and 13 days to 10 months and 6 days. The symptoms were headache in 19 cases, intermittent relief of headache after medical treatment in 6 cases, limitation of body movement or progressive loss of muscle strength in 12 cases, intermittent relief after medical treatment in 3 cases, and dizziness or ataxia in 3 cases. There were 27 cases of T1WI low signal, 5 cases of iso-signal and 2 cases of high signal, 1 case of T2WI low signal, 2 cases of iso-signal and 31 cases of high signal, with mild to moderate edema around the tumor and obvious enhancement, the margin was not “sharp” and slightly blurred, and the occupying effect was disproportionate to the size of the tumor and relatively light. In 23 cases, the tumors were close to the ventricles, 11 cases were located in the cortex, 28 cases were completely resected microscopically, and 6 cases were nearly completely resected microscopically, and the pathology was non-Hodgkin’s lymphoma. Conclusion The clinical imaging features of intracranial lymphoma can make a clear preoperative diagnosis.
