Most arachnoid cysts are asymptomatic, and do not require treatment. Where complications are present, leaving arachnoid cysts untreated may cause permanent severe neurological damage due to the progressive expansion of the cyst(s) or hemorrhage (bleeding). [2] However, with treatment most individuals with symptomatic arachnoid cysts do well.
Treatment is often largely dependent on the type of cyst. Asymptomatic cysts, termed pseudocysts , normally require active monitoring with periodic scans for future growth. [ 7 ] Symptomatic (producing or showing symptoms) cysts may require surgical removal if they are present in areas where brain damage is unavoidable, or if they produce ...
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.
For those with suprasellar arachnoid cysts, it has been discovered that endoscopic ventriculocystocisternostomy is the optimal treatment option. By fenestrating, or opening, the cystic membrane and removing the fluid, all obstructions of the aqueduct were resolved. In patients receiving this treatment, a full recovery is the most common result. [6]
Current treatment options include CSF aspiration, fibrin-glue therapy, laminectomy with wrapping of the cyst, among other surgical treatment approaches. Interventional treatment of Tarlov cysts is the only means by which symptoms might permanently be resolved due to the fact that the cysts often refill after aspiration.
Arachnoid cysts represent <1% of intracranial lesions, with the Sylvian fissure being the most common location, most predominant in males on the left side. [4] Cysts are often discovered incidentally during imaging, and most common associated symptoms are headaches, seizures, and motor deficit due to the pressure the cyst applies to the ...
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 ...
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.
