Abstract in Portuguese
INTRODUÇÃO: A anatomia da face súpero-lateral do lobo occipital é tão complexa e variável que a sua descrição precisa não é encontrada nos livros clássicos de anatomia. Os sulcos e giros occipitais da convexidade cerebral encontram-se descritos com nomenclaturas diferentes de acordo com os diversos autores. O objetivo deste estudo foi investigar e descrever a anatomia da face súpero-lateral lobo occipital e esclarecer a sua nomenclatura. MÉTODOS: As configurações anatômicas dos sulcos e giros na face súpero-lateral do lobo occipital de 20 hemisférios cerebrais foram examinados a fim de identificar os padrões mais característicos e consistentes. RESULTADOS: Os sulcos occipitais mais característicos e consistentes identificados neste estudo foram o sulco intraoccipital, o sulco occipital transverso e o sulco occipital lateral. A morfologia da junção do sulco occipital transverso com o sulco intraoccipital foi identificada como sendo o aspecto mais importante para definir o padrão de giros cerebrais da face súperolateral do lobo occipital. CONCLUSÕES: O conhecimento das principais características dos sulcos e giros occipitais permite o reconhecimento de uma configuração básica do lobo occipital e a identificação de suas principais variações anatômicas

Abstract in English
BACKGROUND: The anatomy of the occipital lobe convexity is so intricate and variable that its precise description is not found in the classic anatomy textbooks, and the occipital sulci and gyri are described with different nomenclatures according to different authors. The aim of this study was to investigate and describe the anatomy of the occipital lobe convexity and clarify its nomenclature. METHODS: The configurations of sulci and gyri on the lateral surface of the occipital lobe of 20 cerebral hemispheres were examined in order to identify the most characteristic and consistent patterns. RESULTS: The most characteristic and consistent occipital sulci identified in this study were the intraoccipital, transverse occipital, and lateral occipital sulci. The morphology of the transverse occipital sulcus and the intraoccipital sulcus connection was identified as the most important aspect to define the gyral pattern of the occipital lobe convexity. CONCLUSIONS: Knowledge of the main features of the occipital sulci and gyri permits the recognition of a basic configuration of the occipital lobe and the identification of its sulcal and gyral variations
