[How certain is the diagnosis of intracerebral tumor bleeding in magnetic resonance tomography?].

Three patients with intracerebral malignant tumours were examined with high-field strength MRI and CT to determine what differences might exist between a haemorrhagic tumour and a genuine intracerebral haemorrhage. Recent literature hint on characteristic signal abnormalities in comparison to pure intracerebral haematoma. However, two of our three patients showed no significant variation, in particular no delay in the evolution of methaemoglobin and no irregular haemosiderin deposition. Up to now the MRI does not seem to be the method of choice to evaluate the aetiology of intracerebral bleeding.
