Temporal lobe epilepsy associated with hippocampal sclerosis and a contralateral middle fossa arachnoid cyst
نویسندگان
چکیده
We report on a 13-year-old boy with temporal lobe epilepsy associated with left hippocampal sclerosis and a contralateral arachnoid cyst in the middle cranial fossa (ACMCF). Chronic intracranial recording from subdural grid electrodes showed the left medial temporal lobe to be the ictal onset zone. After left anterior temporal lobectomy with hippocampectomy, seizure control was improved. ACMCF was not considered the direct cause of epilepsy; instead the seizures were attributed to hippocampal sclerosis.

Abstract Introduction: Arachnoid cysts are developmental cystic lesions which may be found as an incidental finding on neuroimaging or present with symptoms of headache, seizure and neurologic deficit. Presentation with seizure is more common with larger sizes and temporal location. Presentation with TLE is rare, and fenestration of cysts had variable results for seizure control. Here in, we r...

Background: This study compares the clinical characteristics of patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) with those who have temporal lobe epilepsy (TLE) due to other etiologies. Methods : In this retrospective study all patients with a clinical diagnosis of TLE were recruited in a referral outpatient epilepsy clinic at Shiraz University of Medical Sc...
متن کاملArachnoid cysts in the middle cranial fossa: cause and treatment of progressive and non-progressive symptoms.
Ten consecutive patients with arachnoid cysts in the middle cranial fossa, diagnosed by CT, were studied. They were divided into three clinical groups: (1) four patients with progressive symptoms caused by secondary bleeding, (2) five patients with non-progressive symptoms of headache or epilepsy, and (3) one asymptomatic patient. The nine symptomatic patients were operated upon and eight showe...
متن کاملMR imaging of middle cranial fossa arachnoid cysts: temporal lobe agenesis syndrome revisited.
MR studies in eight patients with extraaxial arachnoid cysts in the middle cranial fossa were reviewed in order to identify any associated structural defect in the ipsilateral temporal lobe. The study was prompted by the original theory that agenesis of the temporal lobe is the primary factor in the development of these cysts. Authors of subsequent studies proposed that the cysts are a conseque...
متن کاملTemporal lobe hypogenesis associated with arachnoid cyst in patients with epilepsy.
OBJECTIVE To determine the frequency of temporal lobe hypogenesis (TLH) associated with arachnoid cysts (AC) in patients with epilepsy. METHOD We retrospectively revised 655 consecutive MRI scans from patients followed in our epilepsy clinic. We identified patients with temporal AC and then performed careful visual analysis in a workstation. Patients with evident expansive or destructive lesi...
