Resumo
Este estudo teve por objetivo proporcionar fotos macroscópicas dos nervos cranianos e forames do crânio de equinos comparadas com imagens de ressonância magnética (RM) e tomografia computadorizada (TC), com o intuito de promover a identificação e interpretação precisa da origem e trajeto dos nervos cranianos. Foram obtidas imagens de RM dos nervos cranianos de 11 equinos adultos e imagens dos forames do crânio na TC de 12 equinos adultos. Para ilustrar a anatomia óssea dos forames do crânio, foi realizada a reconstrução 3D. Encéfalos de 11 equinos em conjunto com os nervos cranianos foram retirados do neurocrânio e fixados em solução aquosa de formol a 10%. Após a secagem, os mesmos foram coloridos com esmalte poliuretano e fotografados. A base do crânio de dois equinos foram removidas com os nervos cranianos que foram coloridos e posteriormente fotografados. Adicionalmente, o crânio macerado de um equino também foi utilizado para evidenciação dos forames do crânio. Os nervos cranianos e forames do crânio foram indicados e nomeadas de acordo com livros clássicos de anatomia. As peças anatômicas colaboraram com a identificação da maioria dos nervos cranianos nas imagens de RM e de todos os forames do crânio nas imagens de TC. Uma vez que o conhecimento anatômico é fundamental para a identificação dessas estruturas nas imagens de RM e TC.
The purpose of this study was to provide macroscopic pictures of equine cranial nerves and skull foramina compared to magnetic resonance (MR) and computed tomography (CT) images in order to identify and accurately interpretate the origin and course of cranial nerves. MR imagens of the cranial nerves and CT images of the skull foramina were obtained from 11 and 12 adult horses, respectively. To illustrate the bone anatomy of the skull foramina, 3D reconstruction was performed. Brains and cranial nerves of 11 horses were removed from the neurocranium and fixed in 10% aqueous formalin solution. After drying, they were painted with polyurethane enamel and photographed. The base of the skull with the cranial nerves of two horses were removed, identified by painting and subsequently photographed. In addition, a macerated equine skull was also used to highlight its foramina. The cranial nerves and skull foramina were nominated according to classical anatomy textbooks. MR images provided identification of the majority of the cranial nerves and CT allowed visualization of all skull foramina. Knowledge of the normal brain and skull anatomy is fundamental to accurately interpretate MR and CT images.
