title: [Pseudochoreoathetosis as manifestation of cervical cord lesion. Case report].
abstract: The involuntary movements of choreoathetotic type are commonly regarded as a sign of basal ganglia lesion. However, such movements can also occur in pathological processes involving the cervical spinal cord. This condition is referred to as pseudochoreoathetosis. Involuntary movements can be related to lack of proper coordination between agonist and antagonist muscles, their simultaneous activation due to impairment of reciprocal inhibition. The characteristic feature of pseudochoreoathetosis is proprioceptive sensory loss. In this paper we present 4 patients who developed various involuntary limb movements in early stage of the disease. Lesions in the cervical spinal cord were confirmed by MRI. In case 1 the cause was astrocytoma, in cases 2 and 3--demyelination, in case 4 the precise character of the lesion could not be established. Pseudochoreoathetosis is a rare condition which often remains unrecognized. The presented cases emphasise the importance of early and correct diagnosis leading to proper therapeutical procedure.
