Abstract
Objective To evaluate the CT and MRI imaging features of primary ventricular lymphoma ,so as to provide a reference for the diagnosis and differential diagnosis of the disease .Methods The clinical data and imaging findings of primary ventricular lymphoma in one case was retrospectively analyzed with literature review and compared with primary lymphoma in parenchymal brain .Results Slightly high density tumor presented with regular shape in the trigone of lateral ventricles on CT findings , and slightly low signal intensity on T 1 and slightly high signal intensity on T 2 appeared on MRI findings with small cystic necrosis in tumour .An enhancement scan showed obviously enriched, and there was perilesional edema.After 14 day’s dehydration treatment, rechecked indicated that the lesions were significantly en-larged, the shape were irregula , the area of cystic necrosis was enlarged , heterogeneous enhanced scanning were enhanced , perilesional ede-ma became more heavier , and the imaging feature of “closed fist” appeared .It was proved to be diffuse large B cell lymphoma with surgical pathologic examination , and there was no lymphoma in other regions of the body with whole body PET-CT examination , which was clinically diagnosed as primary ventricular lymphoma .Conclusion Primary ventricular lymphoma is rarely reported ,and it has similar imaging mani-festations with primary lymphoma in parenchymal brain .The combination of multiple imaging modalities will be helpful to diagnosis and dif -ferential diagnosis for the suspected patients .关键词
