ABSTRACT
Malformations of cortical development (MCD) have been increasingly identified. The purpose of this presentation is to review the current knowledge of the MCD. Before we address this issue, we will briefly present a review of cortical development. The second part of this presentation will address the most important MCD. Finally, the last part of this presentation will address the correlation between MCD and epilepsy.
As malformações do desenvolvimento cortical (MDC) são cada vez mais identificadas e diagnosticadas. O propósito desta apresentação é rever o conhecimento recente sobre as MDC. Antes de abordarmos o assunto em questão, apresentaremos brevemente uma revisão sobre a formação cortical. A seguir, abordaremos as principais entidades compreendidas dentro da classificação das MDC e, finalmente, resumiremos a correlação entre MDC e epilepsia.

OBJECTIVE@#This study aimed to clarify the morphology of the Martin-Gruber anastomosis (MGA) in Chinese.@*METHODS@#One hundred and five Chinese upper limbs (36 males and 20 femalese) were dissected to find the connections between medial nerve and ulnar nerve. The MGA was classified as previously described by Lee.@*RESULTS@#MGA was found in 24 cases (22.9%), in 11 of the 36 male and 5 of the 20 female. There was no obvious difference in the frequency of MGA in both upper limbs. Most MGA ulnar position was located at the medial and distal segment of the forearm.@*CONCLUSION@#MGA anatomy could play important role in forensic diagnosis of ulnar nerve injury in Chinese population.

Se revisan las malformaciones congénitas del SNC, señalando aspectos fundamentales sobre sus incidencia, embriopatología, diagnóstico ultrasonográfico y las posibilidades que la terapéutica intrauterina pudiera brindar en algunas de ellas. El objetivo fundamental de esta serie de dos artículos es familiarizar al especialista en neurología, al obstetra, al perinatólogo y al ultra sonografista con los hallazgos fundamentales que aporta la exploración ultrasonigráfica en los casos de ciemopatías del SNC y se trata por ello de lograr una máxima correlación entre las imágenes aportadas por el método y la anatomo-clínica. Considera el autor que la única manera de mejorar la eficacia dignóstica de los ultrasonidos en la etapa perinatal, es familirizándose en las imagenes que se pueden obtener en cada patología, esto redundará en beneficio del paciente intrauterino, el cual será atendido precozmente por manos expertas
