CT-guided chemical rhizotomy of the C1 root for occipital neuralgia
Sensation in the parasagital occipital region is usually provided by fibres from the second cervical root via the greater occipital nerve. In the case presented occipital neuralgia could be relieved only by coagulation of the C1 nerve root with 96% ethyl alcohol. Possible explanations for this observation are discussed and a technique for CT-guided treatment is described.
