[Dissecting aneurysm of the thoracic aorta with paraplegic onset. Diagnosis using computerized tomography]

A case of dissecting aneurysm of the thoracic aorta (De Bakey type III) which first presented as paraplegia of the lower extremities, and the diagnosis of which was confirmed by computerised tomography, is reported. Examination of the literature confirms the rarity of neurological complications especially as an initial symptom. The ischaemia involving areas supplied by the intercostal arteries must be the pathogenetic mechanism of both the paraplegia and the significant increase in sero-enzymes (CPK-MB). The case observed confirms the opinion of other authors that computerised tomography permits rapid diagnosis. As it is also easily performed and not invasive it represents an alternative to conventional angiography.
