The former is located in the epidural space, located between the theca (equivalent to the meningeal layer of the dura) and the periosteum. The latter is located between the inner cortex of the skull and the outer periosteal layer of the dura. It is thus a subperiosteal hematoma on the inside of the skull.\u0026nbsp;\u003c/p\u003e\u003cp\u003eThe equivalent space to the epidural space, located between the meningeal and periosteal layer of the dura is therefore the cavernous sinus or other dural venous sinuses.\u0026nbsp;\u003c/p\u003e","id":2516,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2516","nextQuestionPath":"/articles/extradural-haemorrhage/questions/2515","relatedArticles":[{"id":5053,"title":"Dura mater","link":"/articles/dura-mater?lang=us"},{"id":39884,"title":"Spinal epidural hematoma","link":"/articles/spinal-epidural-hematoma-1?lang=us"}],"alsoUsedIn":[{"id":1230,"kind":"Course","title":"Enhancing Brain Tumours Learning Pathway - page 1230","link":"https://radiopaedia.org/courses/enhancing-brain-tumours-learning-pathway/pages/1230"},{"id":1230,"kind":"Course","title":"Brain Tumours Learning Pathway - page 1230","link":"https://radiopaedia.org/courses/brain-tumours-learning-pathway/pages/1230"}],"stem":"\u003cp\u003eHemorrhage into the\u0026nbsp;epidural space of the spine is anatomically equivalent to which of the following intracranial hemorrhage?\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/2516"}],"attemptsPercentages":[{"alternativeId":"12360","percentage":52},{"alternativeId":"12362","percentage":1},{"alternativeId":"12363","percentage":5},{"alternativeId":"12361","percentage":25},{"alternativeId":"12364","percentage":16}],"promptToLogin":false,"questionManager":false,"articleId":"extradural-hemorrhage"}
