title: [Etiological diagnosis errors corrected by x-ray computed tomography in acute hemiplegia].
abstract: Correlations between the clinical diagnosis on admission and the aetiological diagnosis revealed by computerized tomography (CT) were studied in 248 cases of acute hemiplegia. In 15% of the cases, hemiplegia was not due to a cerebral vascular accident. This mechanism was overestimated in 9% of the cases and missed in 14%. Ischaemia was overestimated in 15% of the cases and haemorrhage in 45%. With regard to transient deficit, CT scans showed that ischaemia was responsible for only 72% of acute hemiplegias, 28% of them being due to haematoma, tumour or subdural haematoma. In many cases where subdural haematoma or tumour was suspected on clinical grounds, CT confirmed that the suspicion was founded.
