Die Wertigkeit von Klinik und bildgebenden Methoden in der Diagnostik von intracerebralen Blutungen bei 100 Patienten

Clinical findings and neuroimaging techniques (cerebral computed tomography - CCT, cerebral magnetic resonance imaging - MRI) were analysed in 100 patients with intracerebral bleeding. 53 patients had haemorrhagic infarctions, 47 patients had intracerebral haematoma. There were no significant differences in the clinical symptoms. Differences were shown in respect of risk factors (significantly more patients with adipositas and alcohol abuse were found in the group with intracerebral haematoma.) Cerebral CT showed in the acute stage a low sensitivity and specificity of 27% in the group of haemorrhagic infarction in contrast to the high sensitivity and specificity of 81% in the group with intracerebral haematoma. There were no relevant differences in CCT results in a two week follow-up (specificity 35% vs 81%). The findings in MRI, apart from differentiation between both groups, conveyed only little information regarding the aetiology of the bleeding with a slight advantage in the group of patients with intracerebral haematoma (17%).
