The authors discuss three case-records of patients referred to CT examination with suspicion of a cerebrovascular attack with difficult differential diagnostic problems. The first two patients had during the initial CT examination a finding very much resembling a haemorrhagic lesion in the thalamic area but with a quite different etiology. In the first case a haemorrhagic cerebral attack was involved, in the second patient a primary tumour. The third case-record is that of a patient with marked discrepancy between the result of the initial examination where a multiple metastatic process in the right hemisphere was diagnosed and the post-mortem finding which proved only red and white malacia.
