Title: CT and MR imaging appearances of intracrebral primary lymphoma
Abstract: Objective To analyze the imaging appearances of intracranial primary lymphoma(IPL) for better diagnosis.Method The 22 cases diagnozed as IPL through clinical and pathologic tests were retrospectively analyzed in regard to appearance,location,signal and enhanced features.Results On MR images,single lesions were found in 14 cases and multiple ones in 8.Among the 40 lesions of 22 cases,14 located in deep brain tissue,5 in white-gray matter junction,8 in basal ganglia and cerebral ganglion,13 in corpus callosum,meningina or endyma infiltration was found in 4 lesions.The location of all lesions was in the supratentorial site.Most tumors presented as round-like mass with well margin or anomalism with slight para-tumor edema and space-occupying effect.On T1WI,the lesions were isointense or slight hypointense signal while on T2WI those were isointense or slight hyperintese signa1.On CT images,22 lesions were isodense or slight high density,18 were low density.Following Gd-DTPA administration,the lesions presented obviously mass-like or annuliform enhancement.Conclusion IPL has certain features in imaging appearance and enhancement pattern;but only combined with clinical manipulations effectively enhancing diagnosis acouracy in just obtained.
