Abstract:
Objective To alanyze the imaging features of brain in systemic NHL.Methods CT and MRI of brain in 8 cases of systemicNHL proved pathologically were performed.Imaging findings of brain were analysed and by comparison with that in 73 cases of brainmetastases with marked enhancement after contrast administration.Results 13 lesions in 8 cases were found by CT,the findings on contrast-enhanced CT included:①Ten lesions showed low density with obscure border;②Three nodular lesions showed high density(including 2 homogeneously and 1 ring-like enhanced nodules).All lesions showed neither ventricle enlargement nor occupying effects.Those enhanced showed no edema around the nodules.Of the 4 cases with MRI,low T_1 signal and high T_2 signal with no change after contrast administrationwere seen in 3 cases.One showed ring-like enhancement with no edema around.While 89% of the 73 brain metastatic cases showeddifferent extent of edema.Conclusion The imaging findings in some of the lesions in this study are different from that described before in literatures.In comparison with other metastases,the marked-enhanced nodules with no edema were found to be a specialty of secondary NHL in brain in our cases.
