Abstract:
Objective To study MRI and CT manifestations and characteristics of primary intracranial lymphoma,and improve the diagnosis and differential diagnosis.Methods Imaging features of primary intracranial lymphoma in 1 1 patients proved by pathology were analyzed retrospectively.Results 9 cases were solitary tumor and 2 cases multiple lesions.Tumors were located in the frontal lobe in 2 cases,the corpus callosum 2 cases,near meningeal 2 cases,the occipital lobe 3 cases.Tumors presented as isodensity or slight hyper density on CT and equal or slight long T1 and T2 signal on MRI.All the lesions were found with obvious homogenous en-hancement;in which 2 cases were found meningeal strengthened;1 case room tube film strengthened.There were slight space occup-ing effect,mostly mild to moderate edema,severe edema in 2 cases.7 typical cases presented “umbilicus sign”,“notch sign”,“lobu-lated”,“incision sign (fist sign)”,and “half month”and so on.Conclusion Imaging manifestations of primary intracranial lymphoma has certain specificity and MRI plays an important role in making accurate diagnosis in the position and qualitative diagnosis.
