Intermittent Compression In Cervical Dystonia: Rare Cause of Myelopathy
Journal Title: Journal of Neurological Sciences-Turkish - Year 2005, Vol 22, Issue 3
Abstract
The clinical and imaging features of two patients of cervical dystonia, who presented with signs & symptoms of myelopathy of recent onset, were studied. MRI documented atlantoaxial subluxation with cord compression and signal change at cervicomedullary junction in the first case, possibly due to overstretching or rupture of transverse ligament by the repeated neck movements. In the second case, there was C4/5 disc bulge. In spite of lack of cord compression, there was cord signal change from C4 to C6 level probably because of intermittent cord compression, ischaemia or ligament stretching due to extreme neck movements. Therefore, secondary myelopathy in patients suffering from cervical dystonia may result from unusual causes such as atlantoaxial instability or due to extreme neck movements superimposed upon degenerative changes. Key Messages: Secondary myelopathy in patients suffering from cervical dystonia may result from unusual causes such as atlantoaxial instability or due to extreme neck movements superimposed upon degenerative changes
