Background: Intracranial dermoid cyst is a rare, benign, nonneoplastic tumor-like lesion that could cause seizures, headache, and hydrocephalus. We hypothesized that the temporal lobe dermoid cyst in combination with other factors were causing the epileptic seizure. Methods: We encountered a 17-year-old girl with anti-seizure medication-resistant epilepsy secondary to dermoid cyst located in the temporal region depicted on magnetic resonance imaging (MRI). She showed neither symptoms of meningitis nor rupture of the cyst according to serial MRI. We hypothesized that temporal lobe dermoid cyst in combination with other factors, such as focal cortical dysplasia (FCD), etc., was causing epileptic seizures in this case. She underwent dermoid cyst removal surgery with resection of the tip of the antero-inferior temporal lobe. Results: Histopathological study showed multiple small intramedullary dermoid cysts in the left antero-inferior temporal lobe in addition to MRI lesions and FCD. Conclusion: A patient with medically intractable epilepsy secondary to left temporal lobe dermoid cyst showed multiple intramedullary dermoid cysts and focal cortical dysplasia that might have interacted to create epileptogenicity. To our knowledge, this is the first case report of dermoid cyst concomitant with FCD.

AbstractBACKGROUND AND IMPORTANCETemporal lobe encephaloceles are increasingly recognized as a potential cause of medically refractory epilepsy and surgical treatment has proven effective. Resection of the encephalocele and associated cortex is often sufficient to provide seizure control. However, it is difficult to determine the extent of adjacent temporal lobe that should be resected. We present a case report and our technique of a tailored inferior temporal pole resection.CLINICAL PRESENTATIONA 32-yr-old man with an 11-yr history of medically refractory epilepsy. Prolonged electroencephalography (EEG) revealed frequent left and rare right frontotemporal sharp waves. Numerous seizures were captured with EEG, all of which originated from the left temporal region. Statistical parametric mapping (SPM) subtraction ictal–interictal SPECT coregistered with magnetic resonance imaging (MRI) (SISCOM) demonstrated ictal hyperperfusion in the anterior left temporal lobe. MRI showed 2 encephaloceles in the left anterior temporal lobe with the accompanying bony defects in the floor of the middle cranial fossa apparent on the computed tomography scan. The patient underwent left temporal craniotomy with intraoperative electrocorticography, resection of the encephaloceles, and a tailored inferior temporal lobectomy (IFTL) and repair of the middle fossa defects. At 7 mo follow up he reported seizure-freedom since surgery.CONCLUSIONResection of temporal encephalocele and adjacent cortex is safe and effective procedure for select patients with medically refractory epilepsy. This video demonstrates our technique which provides a more standardized approach to the resection.

Pathologic findings in surgical resections from patients with temporal lobe epilepsy include a wide range of diagnostic possibilities that can be categorized into different groups on the basis of etiology. This paper outlines the various pathologic entities described in temporal lobe epilepsy, including some newly recognized epilepsy-associated tumors, and briefly touch on the recent classification of focal cortical dysplasia. This classification takes into account coexistent pathologic lesions in focal cortical dysplasia.

Rasmussen’s encephalitis is a well-established, albeit rare cause of medically intractable epilepsy. In a small number of Rasmussen's cases, a second pathology is identified, which independently can cause medically intractable seizures (dual pathology). This paper documents a case of a 13-year-old male who presented with medically intractable epilepsy. The patient underwent a series of surgical resections, early on resulting in a diagnosis of focal cortical dysplasia and later yielding a diagnosis of coexistent Rasmussen’s encephalitis, marked by chronic inflammation, microglial nodules, and focal cortical atrophy, combined with focal cortical dysplasia (Palmini et al. type IIA, ILAE type IIA). The literature on dual pathology in the setting of Rasmussen’s encephalitis is reviewed.

Objective:To report on five patients with temporal lobe epilepsy (TLE) as the unique manifestation of multiple sclerosis (MS).Methods:Among 350 consecutive MS patients, we identified 16/350 (4.6%) who also had epileptic seizures. Here, we review their electrophysiological and clinical features.Results:Five of these 16 patients (four female, one male; mean age 34.2 years; range 31 to 38) with MS and epileptic seizures had an extremely homogeneous clinical picture characterized by TLE as the unique manifestation of MS, even at long follow-up (mean: five years; range 4 to 10). In all patients, seizures started in the second or third decade. Brain MRI revealed at least one juxta-cortical lesion within the temporal region. Antiepileptic medication was always effective.Conclusions:The present study provides the first evidence of a peculiar form of MS characterized by TLE as the unique manifestation of the disease with no disability or MS relapses at long-term follow-up.
