First about the diagnosis of the cyst; this type of cyst is called as arachnoid cyst and this is not an uncommon finding during mri scan of the brain

This cyst is in the area adjacent to the cerebellum part of the brain. This area of the brain controls our coordination and balance. However the cyst is not causing any major issues in your case. It is causing mild mass effect. Mass effect means pressure effect from the cyst, this cyst is causing only mild pressure effect, so we cannot confidently say this cyst is causing all your symptoms. This type of cyst may cause incoordination and imbalance related to the left arm and/or left leg, if you are having these type of symptoms then we can attribute them to the cyst, but the types of symptoms you are having most likely not related to this cyst.

Now to discuss more on arachnoid cysts; first of all please see cysts are fluid filled cavities or sacs. Arachnoid is the term used for arachnoid membrane which is a layer of protective structure covering around the brain. The cysts are called as arachnoid cyst because these cysts arise from the arachnoid membrane. Arachnoid cysts contain CSF (Cerebrospinal fluid) inside them. CSF is a fluid found in the brain and spinal cord regions.

Arachnoid cysts are considered as congenital or developmental cysts in the brain (people are most often born with these cysts). These cysts are not related to any tumor etc, so nothing to worry from that point of view. Also another good news is they do not grow or increase in size - most of the time, and remain the same size throughout the life.

There is no medication treatment for these cysts, and if any treatment is tried then it is surgical like putting a shunt into the cyst and draining the cyst, or excising/removing the cyst etc.

Generally the arachnoid cysts are not treated surgically as they do not cause any symptoms in the patient, and also on most occasions they remain at the same size lifelong. Moreover any brain surgery including an arachnoid cyst surgery carries some risk (bleedings, infections etc) and this is another reason why surgery for the arachnoid cyst is considered as a last resort treatment, and undertaken only when it has to be done and no other option exists.

However if the cyst is growing in size, and clinically if you are developing new symptoms or if your existing symptoms are worsening (progressing) then surgical intervention may be required. If the cyst is growing in size significantly and/or if the patient is considerably suffering from the cyst then surgical intervention is required, not otherwise

And the mri report that is provided to me above has not mentioned about any other brain related finding, in otherwords there is no mentioning of conditions like MS (Multiple sclerosis), strokes, brain tumors, brain infections etc

The types of symptoms you are having also can be secondary to various medical conditions too including the following;

Thyroid disease

Vitamin deficiencies

Autoimmune inflammatory or connective tissue diseases

Chronic infections like lyme etc (if there is risk for lyme) etc

If the above conditions have not already been ruled out then you need investigations to explore the above mentioned possibilities too and then treated appropriately deepening upon the test results

Please let me know if you have any additional questions or if you want to discuss this further.

Assuring you the best services!

Best Regards!
