Can an arachnoid cyst cause memory loss?
Can an arachnoid cyst cause memory loss?
Local ischaemia induced by compression due to an arachnoid cyst may cause memory dysfunction and behavioural disturbances. 3 Untreated, may cause permanent severe neurological damage due to progressive expansion of the cyst. A variety of neurosurgical procedures may be used to decompress the cyst.
Do arachnoid cysts require surgery?
Most arachnoid cysts are stable and do not require treatment. They are four times more common in boys than in girls. Arachnoid cysts are diagnosed with a CT or MRI scan. Treatment, if necessary, involves draining the fluid through surgery or shunting.
What are intradural arachnoid cysts?
Intradural arachnoid cysts commonly present with paraesthesia, neuropathic pain and gait disturbance. Marsupialisation of the SAC heralds immediate and long-term improvement in symptoms. Cysts putatively arise within a dissection in the septum posticum and give rise to both dynamic and static compre …
What is the pathophysiology of Spinal arachnoid cysts?
Spinal Arachnoid Cysts: Presentation, management and pathophysiology Intradural arachnoid cysts commonly present with paraesthesia, neuropathic pain and gait disturbance. Marsupialisation of the SAC heralds immediate and long-term improvement in symptoms.
What happens if arachnoid cysts are left untreated?

How are middle cranial fossa arachnoid cysts classified?
Galassi et al, 5 in 1982, described three types of middle cranial fossa arachnoid cysts based on the size, shape, mass effect on the surrounding brain parenchyma and communication with subarachnoid space on cisternography. It still remains the most widely used classification system in practice.
