Tic convulsivo doloroso: serie de casos y revisión de la literatura

This very rare neurological entity represents less than 1% of rhizopathies and in a large proportion of cases it is caused by vascular compression, attributed to an aberrant dolichoectatic course of the vertebro-basilar complex. The standard modality of treatment is micro-vascular surgical decompression, which has shown greater effectiveness and control of symptoms in the long-term. However medical treatment, which includes percutaneous infiltration of botulinum toxin, has produced similar results at medium-term in the control of each individual clinical manifestation, but it must be considered as an alternative in the choice of treatment.
