Patients with arachnoid cysts may never show symptoms, even in some cases where the cyst is large. Therefore, while the presence of symptoms may provoke further clinical investigation, symptoms independent of further data cannot—and should not—be interpreted as evidence of a cyst's existence, size, location, or potential functional impact on the patient.
Arachnoiditis can be difficult to treat and treatment is generally limited to alleviation of pain and other symptoms. [25] While arachnoiditis may not yet be curable with the potential to be life-altering, management including medication, physical therapy , and if appropriate, psychotherapy, can help patients cope with the difficulties it presents.
Many CNS cysts form in the womb during the first few weeks of development as a result of congenital defects. [7] In adults cysts may also form due to a head injury or trauma, resulting in necrotic tissues (dead tissue), and can sometimes be associated with cancerous tumors or infection in the brain. However, the underlying reasons for cyst ...
Arachnoid cyst: A defect caused when CSF forms a collection that is trapped in the arachnoid membranes. The resulting cyst can then block the normal flow of CSF from the brain resulting in hydrocephalus as well as other defects. The most common locations for an arachnoid cyst are the middle fossa and the posterior fossa. The most common ...
Tarlov cysts are most commonly located in the S1 to S4/S5 region of the spinal canal, but can be found along any region of the spine. They usually form on the extradural components of sacrococcygeal nerve roots at the junction of dorsal root ganglion and posterior nerve roots and arise between the endoneurium and perineurium. [10]
Absent tibia-polydactyly-arachnoid cyst syndrome, also known as Holmes-Collins syndrome, is a very rare multi-systemic hereditary disorder which is characterized by facial dysmorphisms, [1] pre/post-axial polydactyly, toe syndactyly, missing/underdeveloped tibia bone, and the presence of a retrocerebellar arachnoid cyst.

Treatment to remove these tumors always involve radical surgery. The reported recurrence rate for a subtotal removal is 30% after a mean interval period of 8.1 years. [4] Surgery is the primary treatment for removal of the brain tumor. Use of an endoscope may assist on obtaining a more complete surgical removal from hidden recesses. [5]
