摘要
Abstract
Objective To study the magnetic resonance imaging(MRI) characterizations of inlracranial primary malignant lymphoma. And analyze the causes of misdiagnosis before surgery in order to improve diagnostic accuracy. Methods The MRI characteristics of normal scan, enhanced scan and diffusion weighted imaging(DWI) of 18 cases with pathologically confirmed primary intracranial lymphoma(diffuse large B cell type) were analyzed retrospectively. Results Fifteen cases were of single lesions, and 3 cases were of multiple lesions, of which 1 case in brain stem, 1 case in small cranial vermis, 14 cases in large cranial hemisphere, 1 case in basal ganglia, and 1 case in right mound skull. Four cases were misdiagnosed (all were diagnosed as glioma in brain). Pathological results of 18 cases were diffuse large B-cell non-Hodgkin's lymphoma. Eighteen oases of space occupying lesions appeared as mass, T|WI showed low or equal signal: T2WI showed equal or a little higher signal. After magnetic enhanced scanning, non-necrosis niduses were all characterized as even significantly enhanced, but for the nidus following with necrosis, the area of which was not enhanced. There were 16 cases with moderate peripheral edema, and 2 cases of severe peripheral edema. The DWI array scan results of 10 cases showed the nidus presented high signal performance. Conclusion MRI performance of intracranial primary malignant lymphoma has a regular pattern. The comprehensive analysis of normal scan, enhanced scan and DWI can improve the diagnosis accuracy. The features of DWI possess a certain reference value to diagnosis and differential diagnosis.关键词
