Spinal cord tumors are classified based on their location within the spinal cord: intradural (intradmedullary and extramedullary) and extradural tumors. [citation needed] Intradural tumors are located within the dura mater. [1] These are further broken down into intramedullary and extramedullary tumors.
In anatomy, the epidural space is the potential space between the dura mater and vertebrae . [ 1 ] [ 2 ] The anatomy term "epidural space" has its origin in the Ancient Greek language; ἐπί , "on, upon" + dura mater also known as "epidural cavity", "extradural space" or "peridural space".
An epidural hematoma is a collection of blood between the dura and the inner surface of the skull, and is usually due to arterial bleeding. Intradural procedures, such as removal of a brain tumour or treatment of trigeminal neuralgia via a microvascular decompression , require that an incision is made to the dura mater.
Epidural hematoma is when bleeding occurs between the tough outer membrane covering the brain (dura mater) and the skull. [4] When this condition occurs in the spinal canal, it is known as a spinal epidural hematoma .
Epidural hemorrhage (extradural hemorrhage, EDH) which occur between the dura mater (the outermost meningeal layer) and the skull, is caused by trauma. It does not cross the suture lines of the skull because the superifical dural layer is attached tightly to the skull along the suture lines.
Epidural anaesthesia is a technique whereby a local anaesthetic drug is injected through a catheter placed into the epidural space. This technique is similar to spinal anaesthesia as both are neuraxial, and the two techniques may be easily confused with each other. Differences include:
A new study says that elderberry juice could help people lose weight, regulate their metabolism, and regulate their gut microbiome. Here's what a doctor thinks.
Spinal arachnoid cysts may be extradural, intradural, or perineural and tend to present with signs and symptoms indicative of a radiculopathy. [23] Arachnoid cysts may also be classified as primary (congenital) or secondary (acquired) and have been reported in humans, cats, and dogs. [24]
