Progressive facial hemiatrophy (PFH), a rare disorder characterized by progressive and self-limited atrophy of the skin and the subcutaneous tissues, is often associated with epilepsy but the link between these two conditions is poorly understood. The cause of PFH remains unclear. We report four patients with PFH associated with partial epilepsy in whom brain MRI showed cerebral dysgenesis. The four patients (two men, two women; age range: 24 to 73 years) developed parasagittal PFH in their second decade. Seizures started before the age of 20 years in three patients and were refractory simple, or complex partial seizures. All the patients had focal MRI showing cortical dysgenesis, ipsilateral to PFH, consisting of cortex thickening, gyral effacement, and blurring of the white-gray interface. The underlying white matter was hyperintense on T2-weighted sequences, with nodular areas in two patients. These areas were stable over time, without contrast enhancement, and were consistent with the MRI characteristics of cystic encephalomalacia. These neuroradiologic features suggest a localized cerebral hemispheric defect of congenital origin. Because cells participating in the formation of the fronto-nasal bud derive from common progenitors with the cells that give rise to the cerebral hemisphere, we suggest that an early malformative process affecting one side of the rostral neural tube could underlie both cerebral dysgenesis and facial hemiatrophy.

A 39-year-old woman presented with typical panic disorder symptoms of two years duration. Imipramine (IMI) treatment yielded complete remission of her symptoms for three years. At that time, however, her symptoms recurred. Neither increasing the IMI dose nor an adequate trial of fluoxetine controlled her symptoms. Further history revealed subtle changes in her symptoms suggestive of complex partial seizures. Scalp EEG was normal, but an MRI revealed multiple meningiomas. Her symptoms remitted completely on carbamazepine. This case illustrates the phenomenologic overlap between panic attacks and complex partial seizures, and a neuroanatomic overlap between the two syndromes is hypothesized.

We studied clinical features and seizure localization in 14 patients with porencephaly and intractable seizures. Perinatal complications were present in nine patients, childhood febrile convulsions in two, congenital hemiparesis in 12, and intellectual impairment in seven. Ten patients had psychoparetic complex partial seizures (CPS), three had sensorimotor simple partial seizures, and one had generalized tonic-clonic seizures. Surface EEG showed temporal onset in nine patients (one bitemporal) and extratemporal onset in four. MRI showed porencephaly in the distribution of the middle cerebral artery in eight patients, posterior cerebral in three, internal carotid in one, and multiple vessels in two. MR-based volumetry revealed hippocampal formation atrophy in 13 patients (eight unilateral and five bilateral) and amygdalar atrophy in 10 patients (nine unilateral and one bilateral). Hippocampal formation atrophy was concordant with CPS semiology in 10 patients (71%) and with EEG temporal localization in nine patients. Two patients had pathologic confirmation of mesial temporal sclerosis and were seizure free after temporal lobectomy. We conclude that mesial temporal sclerosis often coexists with porencephaly and is the likely seizure focus in the presence of concordant electroclinical data. This recognition implies that effective surgical intervention can be offered to certain patients with porencephaly-related seizure disorders. The dual pathology and association with perinatal cerebral vascular occlusion suggest a common ischemic pathogenesis.

We encountered a case of focal encephalitis. A 5-year-old boy developed high fever and he was admitted to our hospital on the third day with generalized tonic-clonic convulsions. Cerebrospinal fluid showed slight pleocytosis. CT showed diffuse low-density area in the left temporal, parietal and occipital regions. T2 weighed MRI showed swelling and hyperintense regions in the left temporal, parietal and occipital cortex. With the disappearance of generalized convulsion, the cortical swelling improved. But aphasia and intractable complex partial seizures appeared. On MRI, the atrophic findings of the left hippocampus and temporal lesion became developed. We considered this case corresponds to focal encephalitis related to "a peculiar type of post-encephalitic/encephalopathic epilepsy" reported by Awaya et al.

We describe an unusual clinical presentation of a ganglioglioma in a patient with complex partial seizures. The patient underwent a right temporal lobectomy with subtotal tumor resection at age 15 years, followed by a complete resection 1 year later. Follow-up MRI scan a year later documented recurrence and leptomeningeal dissemination. Another biopsy was performed. Pathological examination revealed similar histology in all three resections, with a ganglioglioma showing no evidence of anaplasia. The tumor exhibited a number of karyotypic abnormalities, notably, a paracentric inversion of chromosome 7. In summary, despite lacking anaplastic features by conventional histological criteria, this ganglioglioma showed an unsusual karyotype and demonstrated radiological evidence of widespread dissemination.

Mesial temporal sclerosis is the main pathological substrate present in refractory temporal lobe epilepsy and its presence is often related to the occurrence of febrile seizures in infancy. There is an on-going discussion on the nature of mesial temporal sclerosis as it related to epilepsy: cause or consequence. A previously normal child developed hyperosmolar coma after abdominal surgery at the age of 6. Three months afterwards he developed simple and complex partial seizures with an increasing frequency and refractory to multiple mono- and polytherapic drug regimens. He was evaluated for surgery at the age of 13. Ictal and interictal recordings showed left temporal lobe abnormalities. Early CT scanning suggested left temporal atrophy. MRI showed mesial temporal sclerosis. Neuropsychological testing showed verbal memory deficits and he passed a left carotid artery amytal injection. He was submitted to a cortico-amygdalo-hippocampectomy and has been seizure-free since then. The clinical data obtained from this patient suggest that at least in this case mesial temporal sclerosis would be related to the cause of epilepsy and not resultant from repeated seizure activity.

Insular epilepsy has been rarely reported and its clinical and electrographic features are poorly understood. The electrographic study of the insula is difficult since it is hidden from the brain surface by the frontal and temporal lobe. A 48 years-old woman started having simple partial autonomic and complex partial seizures with automatisms and ictal left arm paresis 8 years prior to admission. Seizure's frequency was 1 per week. Pre-operative EEG showed a right temporal lobe focus. Neuropsychological testing disclosed right fronto-temporal dysfunction. MRI showed a right anterior insular cavernous angioma. Intraoperative ECoG obtained after splitting of the sylvian fissure showed independent spiking from the insula and temporal lobe and insular spikes that spread to the temporal lobe. The cavernous angioma and the surrounding gliotic tissue were removed and the temporal lobe was left in place. Post-resection ECoG still disclosed independent temporal and insular spiking with a lower frequency. The patient has been seizure-free since surgery. Insular epilepsy may share many clinical and electroencephalographic features with temporal lobe epilepsy.

We studied the interictal EEG of 50 epileptic patients (28 males, 22 females) who had parenchymal neurocysticercosis, diagnosed by CAT/MRI of the brain, positive immunological reaction for cysticercosis in cerebral spinal fluid or both. Age ranged from 5 to 61 years old; the mean age of onset was 24.2 +/- 12.2 years. Thirty-six patients had generalized seizures, 13 partial seizures with secondarily generalized seizures, and 1 had complex partial seizures. Twenty-two patients had parenchymal calcifications (inactive form); 21 had parenchymal cysts (active form) and 7 had both. EEG was abnormal in 14 patients (28%): 8 had focal slowing, 3 had focal sharp or spike activity, and 3 had both. The EEG was normal in patients with inactive forms of neurocysticercosis. The EEG was abnormal in 50% of patients with active and mixed forms of neurocystercosis and in 48% of patients with active form only. We conclude that the active forms of neurocysticercosis should be suspected when the EEG is found to be abnormal. In additional, EEG abnormality does not depend on the number of lesions, but rather on location and viability of the cysts, and on host response.

We report a case of von Recklinghausen's disease associated with multiple intracranial arterial occlusion ("moyamoya-like") and a fusiform aneurysm. A 28 years-old man with type I neurofibromatosis presented with syncope, complex partial seizures and mental deterioration. After an acute headache episode associated with meningeal signs, drowsiness, and hemorrhagic CSF, the patient was evaluated with cranial CT scan, MRI and angiogram that revealed an obstructive arteriopathy compatible with moyamoya disease and a fusiform aneurysm in the posterior circulation. The authors discuss the clinical and radiological findings and the therapeutic decision in this case comparing with the few similar reports in the medical literature. Recognition of an underlying rare genetic disorder may be of considerable importance in young patients presenting with seizures.

This is the second report of musicogenic epilepsy in Japan. A 23-year-old woman was admitted to our hospital due to the musicogenic epilepsy. She had four generalized tonic clonic seizures at 18 and 19 years old. Since 19, she had had complex partial seizures lasting for about 20 seconds which was easily evoked by listening to an American pops particularly "Dreamlover" song by Mariah Carey. Brian MRI and interictal 99mTc HMPAO-SPECT showed no abnormalities. In the ictal EEG recording, three minutes after listening to the song, seizure activities were recorded from the right temporal region with 11Hz rhythmic epileptiform activities over the right temporal region and subsequent delta activities over the right hemisphere. The song that induced the seizure had a specific meaning that might evoke her emotion as had been pointed out in the previous reports.
