[Intracranial lymphoma. Radiologic findings in 40 patients].
We analysed the radiologically findings of 40 patients with histologically confirmed cerebral lymphoma but without AIDS in a retrospective study; 31 of these had primary cerebral lymphoma without any other manifestation of the disease. All patients had CT, 24 had angiography and in five patients MRT had been performed in addition. CT showed a solitary lesion in 60%, of these 62% had scalloped margins and 38% were nodular, 34% were isodense and 57% were hyperdense. Following contrast injection, there was increased density in 97% of the lesions. The most frequent localisation was in the region of the basal ganglia and the corpus callosum (33%), in the frontal lobes (30%) and in the temporal lobes (20%). Angiographically, 63% showed evidence of a space-occupying lesion, there were vascular irregularities in 33% and tumour contrast in 21%; in 25% of the patients angiography was normal. Early venous filling was not found in any case. T1 weighted sequences during MRT of 5 patients showed the tumour to be isointense or slightly hypointense. T2 weighted images showed the tumour to be hyperintense or with mixed signal intensities.
