Hi my son is 16 months old and from the age of 8 weeks he was diagnosed with a moderate sized posstereier fossa arachnoid cyst can the cyst be surgically removed the measurements of the cyst are 4.3cm (AP) 4.1cm ( transverse) 4.2cm (cranioaudal)There is tentorium and transverse dural venous sinus and there is expansion of the left posterior fossa. The left cerebellar hemisphere is also slightly hypoplastic and anteriorly displaced as a result of the arachnoid cyst
Hello, Usually when there are no symptoms arachnoid cyst need not be treated. Only when there are symptoms of increased intracranial tension or if there are any focal neurological deficits or seizures, they need to be evaluated further please. Hope I have answered your query. Let me know if I can assist you further. Take care.
