Occipital Neuralgia in Chiari I Malformation: Two Different Events or Two Different Faces of the Same Event?
نویسندگان
چکیده
Occipital neuralgia (ON) is characterized by severe pain in the occipital region due to an irritation of the occipital nerves. Traumatic injuries, mass or vascular compression, and infective and inflammatory processes could cause ON. The dislocation of a nerve/muscle/tendon, as can happen in malformations such as the Chiari I malformation (CIM), also can be responsible. Usually, headaches associated with CIM and ON are distinguishable based on specific features of pain. However, the diagnosis is not easy in some cases, especially if a clear medical history cannot be accurately collected. Determining if the pain is related to ON rather than to CIM is important because the treatments may be different.

INTRODUCTION Trigeminal neuralgia (TN) is characterised by recurrent episodes of sudden, intense, usually unilateral, lancinating pain confined to the distribution of one or more branches of the trigeminal nerve. It is most commonly associated with compression of the trigeminal nerve root by an artery or vein, which is thought to lead to irritability of the nerve root due to demyelination and r...

متن کاملChiari malformation with thick occipital bone.
A case of a Chiari malformation with an extraordinarily thick occipital bone is described. The thick occipital bone might make the posterior fossa narrow with consequent herniation of the cerebellar tonsils to the foramen magnum and formation of a syrinx. At dural plasty, well-developed marginal and occipital sinuses should be deliberately handled with the preservation of normal venous drainage...

Chiari malformation type III is an extremely rare anomaly characterized by a small posterior fossa and a low occipital/high cervical encephalocele with herniation of the posterior fossa contents (that is, the cerebellum and/or the brainstem, occipital lobe, and fourth ventricle). We report a case of Chiari malformation type III in a neonate, discuss the etiopathogenetic and radiological feature...

The present study evaluated two of the most applied surgical techniques to treat CM 1. Method 32 patients were evaluated and divided in two groups: group 1 had 16 patients that were submitted to decompression of occipital bone and dura mater of the craniovertebral junction (CV...
