Complete resolution of medically refractory temporal lobe epilepsy after arachnoid cyst fenestration.
Intracranial arachnoid cysts are congenital lesions that are frequently detected incidentally. About 30% of patients have a symptomatic epileptic seizure as the presenting symptom, occasionally with other focal neurologic signs. A case is presented of a young male patient with medically refractory temporal lobe epilepsy. Following his neurological examination, epileptic zone was defined in the right temporal lobe that correlated with the MRI-detected sylvian arachnoid cyst. Microneurosurgical cyst fenestration with volume reduction was performed, which resulted in a decremental but eventually complete seizure freedom. In conclusion, the arachnoid microsurgical cyst reduction is a safe procedure and may result in complete remission of symptomatic epileptic seizures and favorable outcomes, as reported in other studies.
