Abstract
Arachnoid cysts (ACs) can be associated with epilepsy. The true prevalence and incidence of this association can’t be determined because imaging is not systematically performed in all epilepsy types and is not always available. The relationship between epilepsy and ACs is a matter of debate. For some authors, ACs should be considered incidental. Others suggest a possible causal relationship based on the favorable outcome of epilepsy after cyst surgery in some studies. Many factors have been proposed as possible mechanisms of epileptogenesis in ACs such as compression, increased level of excitatory amino acids within the cystic fluid, alteration of blood perfusion in the surrounding cortex, or the association with parenchymal lesions. Different types of seizures were reported in association with ACs, mainly focal in nature. The majority of ACs are located within the middle cranial fossa; however, most studies suggest that they may not be related to a specific seizure type and electroencephalographic (EEG) focus. The first step in the diagnostic workup should be to classify as accurately as possible the type of seizure and the epileptic syndrome. Cases can then be classified into three groups. The first group comprises the epileptic syndromes that are traditionally not associated with lesions such as idiopathic generalized epilepsy whereby the AC is probably incidental. In the second group, AC is associated with other lesions that are known to cause epilepsy. Electroclinical and imaging correlation should be reviewed to confirm whether the AC or the associated abnormality causes the seizures. Video EEG, positron emission tomography (PET), or single-photon emission computed tomography (SPECT) can be performed to detect the epileptogenic focus. The third group comprises cases where there are neither associated brain lesions on magnetic resonance imaging nor criteria for a nonlesional epileptic syndrome. Video EEG, PET, or SPECT may help localize the seizure focus. When it is near the AC, intraoperative corticography or intracranial EEG recording might be required to localize an abnormality in the surrounding cortex. There is currently no consensus regarding the choice of treatment or the ideal technique when surgery is considered. Management should be performed by a multidisciplinary team. There is an urgent need for prospective multicentric studies pooling the accumulated data from multiple institutions to obtain a large sample size that would allow the study of the relationship of AC to epilepsy, treatment indications, the most suitable surgical technique when surgery is considered, and the clinical outcome.
