To our knowledge, this is the first report of mesial temporal lobe malformation associated with chromosomal abnormalities. Our finding may contribute to the understanding of the genetic mechanisms involved in central nervous system malformations, especially in the mesial temporal lobe structures.
-The occurrence of de novo psychogenic seizures after epilepsy surgery is rare, and is estimated in 1.8% to 3.6%. Seizures after epilepsy surgery should be carefully evaluated, and de novo psychogenic seizures should be considered especially when there is a change in the ictal semiology. We report a patient with de novo psychogenic seizures after anterior temporal lobe removal for refractory temporal lobe epilepsy. Once psychogenic seizures were diagnosed and psychiatric treatment was started, seizures stopped.KEY WORDS: psychogenic seizure, epilepsy surgery. Crises psicogênicas de novo após cirurgia de epilepsia: relato de casoRESUMO -A ocorrência de crises psicogênicas de novo após cirurgia de epilepsia é rara, e é estimada em 1,8% a 3,6%. Crises após cirurgia de epilepsia devem ser cuidadosamente avaliadas, e crises psicogênicas de novo devem ser consideradas especialmente quando houver uma mudança na semiologia ictal. Relatamos o caso de uma paciente com crises psicogênicas de novo após lobectomia temporal anterior realizada para tratamento de epilepsia temporal de difícil controle. Uma vez feito o diagnóstico de crise psicogênica e iniciado tratamento psiquiátrico, as crises foram controladas. PALAVRAS-CHAVE: crise psicogênica, cirurgia de epilepsia.Seizure recurrence following surgical treatment of refractory epilepsy is usually characterized by events which are similar to the preoperative ones, and may indicate a poor prognosis. Acute postoperative generalized tonic-clonic or focal motor seizures associated with a precipitating factor such as subtherapeutic antiepileptic drug (AED) blood levels, meningitis or metabolic disturbances often have a good prognosis 1 .Except for changes in duration of ictal and post-ictal symptomatology, seizures clinically different from those recorded before surgery are rare, and may represent psychogenic seizures 2 .We report a patient with de novo psychogenic seizures after anterior temporal lobe removal for refractory temporal lobe epilepsy. CASEAn 18 year-old right handed girl experienced her first seizure at age 11. During the following years seizures increasingly became more frequent, and by the time she was 17 years-old she had four or five complex partial seizures every 10 to 15 days. Seizures were characterized by staring,
-We studied the clinical, EEG and MRI findings in 19 patients with epilepsy secondary to congenital destructive hemispheric insults. Patients were divided in two groups: 10 with cystic lesions (group 1), and 9 with atrophic lesions (group 2). Seizure and EEG features, as well as developmental sequelae were similar between the two groups, except for the finding that patients of group 2 more commonly presented seizures with more than one semiological type. MRI showed hyperintense T2 signal extending beyond the lesion in almost all patients of both groups, and it was more diffuse in group 2. Associated hippocampal atrophy (HA) was observed in 70% of group 1 patients and 77.7% of group 2, and it was not correlated with duration of epilepsy or seizure frequency. There was a good concordance between HA and electroclinical localization. The high prevalence of associated HA in both groups suggests a common pathogenesis with the more obvious lesion. Our findings indicate that in some of these patients with extensive destructive lesions, there may be a more circumscribed epileptogenic area, particularly in those with cystic lesions and HA, leading to a potential rationale for effective surgical treatment.KEY WORDS: epilepsy, magnetic resonance image, hippocampal atrophy.Epilepsia secundária a lesões destrutivas hemisféricas congênitas: achados clínicos e relevância de atrofia hipocampal associada RESUMO -Analisamos os achados clínicos, de EEG e RM de 19 pacientes com epilepsia secundária a insultos destrutivos hemisféricos congênitos. Os pacientes foram divididos em dois grupos: 10 com lesões císticas (grupo 1), e 9 com lesões atróficas (grupo 2). As características das crises e achados de EEG foram similares entre os dois grupos exceto pelo fato dos pacientes do grupo 2 terem apresentado mais comumente crises com mais de um padrão semiológico. A RM mostrou sinal T2 hiperintenso estendendo-se ao redor da lesão e à distância em quase todos os pacientes de ambos os grupos, de modo mais extenso no grupo 2. Observou-se atrofia hipocampal (AH) associada em 70% dos pacientes do grupo 1 e 77,7% do grupo 2 e não houve correlação com a duração da epilepsia ou freqüência das crises. Houve boa correlação entre a AH e localização eletroclínica. A alta prevalência de AH associada em ambos os grupos sugere uma patogenia comum com a lesão mais óbvia. Estes achados indicam que alguns destes pacientes com extensas lesões destrutivas, particularmente aqueles com lesões císticas e AH, a zona epileptogênica pode ser mais circunscrita possibilitando a indicação de uma ressecção restrita para o controle das crises. PALAVRAS-CHAVE: epilepsia, ressonância magnética, atrofia hipocampal.
