Diagnosed With CM 1. Have Burning Sensation On Head And Numbness On Face. Eyes Feel Swollen. Have Cyst In Sinus Cavity. Help?
Thank you for writing in.
Your symptoms are consistent with left sided trigeminal neuralgia (nerve which supplies face, forehead region,jaw and mandible).Symptoms are mostly due to chiari malformation type 1.
In chiari malformation type 1 there is herniation of cerebellar tonsil of more than 3mm beyond foramen magnum.Sometimes medullary kinks and brainstem herniation are also seen associated with it.This stretches nucleus of trigeminal nerve located at brainstem and produce such symptoms.
It is worthwhile to consult neurologist for clinical examination and further plan.She may also require repeat MRI at cevicomedullary junction to confirm it .
Meantime,avoid strennous activities.You may require neuralgic drugs (like pregabalin or gabapentin or carbamazepine ) for facial pains, along with vitamin B12 preparation.
Hope I have answered your query.Please get back if you require any additional clarification.If you are satisfied with my answer ,kindly rate my answer.

Q)What is the cevicomedullary junction?
A)It is the junction between cervical spinal cord and medulla (lowermost part of brainstem).To look for medullary stretching and syrinx (cavity in the centre of cervical cord)
Q Dos e of B12 ?
A)500 microgram daily.In some patients of trigeminal neuralgia injection methylcobal (Vitmanin b12) alternate days has relieved their symptoms along with neuralgic drugs
Q) Gabapentin 400mg /day ?
a) It is minimal dose can be hiked as per your symptoms to XXXXXXX 1800 mg
b) Combination of nortryptine along with gabapentin is useful to control neuralgic pain not responding to gabapentin alone
c) other drugs like carbamezipine, baclofen also can help you to relieve your symptoms
All has to discussed with your treating doctor
Q) Will Strennous activities make my condition worse?
A) Yes strennous activities can worsen neuralgic pain secondary to chiari malformation.
Q) Why would my neurologist tell me on my first visit that the CM 1 was the cause of this pain and on the second visit say no and wants me to see another neurologist for other explanations?
A) Based on history you have trigeminal neuralgia.There are many causes for it. CM can produce it,other causes are idiopathic, vasculitis , demyelination. May be he want to make sure that vasculitis has produced it ( Inview of raynauds phenomenon,? sjogren, ? may be MRI does not reveal medullary compression)
There are many treatment options for CM1.If neuralgic symptoms are related to CM1 and not effective by medical treatment as mentioned ,then surgery is required.If neuralgia is secondary to vasculitis then steroids are indicated
Surgery (For CM) is the only treatment available to correct functional disturbances or halt the progression of damage to the central nervous system. Most individuals who have surgery see a reduction in their symptoms and/or prolonged periods of relative stability. More than one surgery may be needed to treat the condition.
Posterior fossa decompression surgery is performed on adults with CM to create more space for the cerebellum and to relieve pressure on the spinal column. Surgery involves making an incision at the back of the head and removing a small portion of the bottom of the skull (and sometimes part of the spinal column) to correct the irregular bony structure. The neurosurgeon may use a procedure called electrocautery to shrink the cerebellar tonsils. This surgical technique involves destroying tissue with high-frequency electrical current
Hope this will help you

Based on your MRI there is nothing suggestive of compression at the brain and brainstem .There is no comments on cervical cord on your MRI reports.
Blurred vision and confusion cannot be explained based on your MRI brain reports. CM1 does not produce blurred vision and confusion unless it is associated with hydrocephalus (enlarged ventricle).There is no role of decompression surgery if symptoms are not related to CM1. This is the first time in your discussion you mentioned blurred vision and confusion.
There are many causes of blurred vision ,One can exactly find the cause, based on fundus examination and acuity of vision testing.
Detailed higher mental function and meningeal signs to be tested and based on it further tests needed to know the cause of confusion (blood sugar, serum electrolyte,and thyroid profile.

Based on the details of MRI brain and cervical cord you seems to have chiari malformation type 1 with out any compression at the brainstem and cervical spinal cord (in view of MRI showing normal brainstem and absence of syrinx).
Though your cervical spine does not show syrinx secondary to CM1 but it shows features of spine degeneration leading to disc osteophyte and mild to moderate spinal canal stenosis with mild cord compression.This might also cause damage to descending tract of trigeminal nerve resulting in sensory loss , facial numbness,and facial pains . Hence you may get benefited with short course of steroids in view of cord compression. Blurring of vision in evening can also be produced by cervical cord edema impinging the cervical sympathetics that supply pupils of eye ( leading to condition called horners syndrome)
Hence it should be emphasized that clinical examination for horners , pattern of sensory loss will help one to confirm it.
Discuss with treating doctor regarding same.You may require opinion of neurosurgeon also.
I apologize for delay in response
I hope this helps you.
