ARACHNOID CYST INFORMATION |
|
|
|
Arachnoid cysts are fluid-filled sacs that occur on the arachnoid membrane that covers the brain (intracranial) and the spinal cord (spinal). There are three membranes covering these components of the central nervous system: dura mater, arachnoid, and pia mater. Arachnoid cysts appear on the arachnoid membrane, and they may also expand into the space between the pia mater and arachnoid membranes (subarachnoid space). The most common locations for intracranial arachnoid cysts are the middle fossa (near the temporal lobe), the suprasellar region (near the third ventricle) and the posterior fossa, which contains the cerebellum, pons, and medulla oblongata.
?In many cases, arachnoid cysts do not cause symptoms (asymptomatic). In cases in which symptoms occur, headaches, seizures and abnormal accumulation of excessive cerebrospinal fluid in the brain (hydrocephalus) are common. The exact cause of arachnoid cysts is unknown.
Arachnoid cysts are classified according to location.

Jaxson's cyst was found around 6 months of age. He was behind in all aspects of his development, mostly due to his Brachial Plexus injury and Torticollis. However, his doctor wanted him to be seen by a nuerologist JUST in case. He went in for his first MRI and then we found out he had a midline Arachnoid Cyst. His cyst is located in the exact spot of his hematoma that he had at birth.
He has had a couple MRI's as follow ups to be sure it isn't growing, and is due for another in the fall of 2005. I do not know what will happen, if he will have severe symptoms like some stories I have read about. I am hopefull that he will be ok. He has already been through one traumatic skull surgery, another would be horrible.
I continue to do as much reseach as possible on AC's, and really consider www.arachnoidcyst.org a great site for info. I will update this page as I know more. |
