AI Article Synopsis
- Pathologies in the spinal epidural space (SES) can cause issues like thecal sac narrowing or spinal cord compression, and they are categorized into several types: degenerative, infective, neoplastic, vascular, and traumatic.
- The review discusses various degenerative conditions, notably lesser-known ones, as well as infectious conditions like spondylodiscitis, which can lead to epidural phlegmon or abscess.
- MRI is highlighted as the primary imaging tool for examining SES abnormalities, with complementary imaging methods like CT or X-rays helping to evaluate bones and foreign objects.
Article Abstract
Pathologies affecting the spinal epidural space (SES) comprise various abnormalities. However, they all have the potential to cause thecal sac narrowing or spinal cord compression. In this review, we group these pathologies into degenerative, infective, neoplastic, vascular, traumatic, and others, focusing on their imaging features. Degenerative pathologies of the SES range from disc to facet disease, with a particular emphasis on the less common degenerative pathologies in this review. Infective pathologies affecting the epidural space include spondylodiscitis and associated epidural phlegmon and abscess. Neoplasms arising from typical SES components include neurofibroma, hemangioma, and liposarcoma. MRI is the best modality to assess the anatomy and abnormalities of the epidural space. MRI, combined with computed tomography, or a radiograph, is useful for the evaluation of bones or radiopaque foreign bodies.

Pneumocephalus following a combined spinal-epidural technique: a case report.

Pneumocephalus refers to the presence of air within the intracranial cavity, and albeit its occurrence following neuraxial techniques is rare, it is commonly associated with a loss of resistance to air technique. This case report describes a parturient who underwent neuraxial analgesia for pain management during labour. Epidural space identification with loss of resistance to saline technique was used and she went on to develop a symptomatic pneumocephalus.

Rationale: Pneumorachis is an uncommon lesion of the spinal canal, which is often asymptomatic. The pathogenesis and treatment strategies are uncertain because only a few cases have been reported. Some patients were treated with percutaneous aspiration or percutaneous endoscopic treatment, but poor pain release and symptom recurrence were observed.

Spinal cord stimulation (SCS) represents a therapeutic approach for chronic pain management in patients refractory to conventional treatments. By implanting electrodes in the epidural space, SCS aims to mitigate pain transmission to the brain through electrical stimulation, often resulting in sensory perceptions such as paresthesia. This study investigates the influence of electrode configurations on electrical parameters, including current density and electric potential, within the spinal cord environment.

Epidural analgesia is an effective way to manage pain for labor and delivery, surgery, trauma, cancer, and neuropathic pain. It involves the administration of local anesthetics and/or opioids into the epidural space. To ensure its efficacy and safety, nurses must understand the basic anatomy and pharmacology of epidural analgesia, considerations when monitoring patients, and identify its adverse reactions.

Background: This study evaluated the spread of a local anesthetic, using MRI and sensory blockade, after an intertransverse process block (ITPB) at the medial aspect of the retro-superior costotransverse ligament (retro-SCTL) space - the medial retro-SCTL space block.
Methods: Ten healthy volunteers received a single-injection ultrasound-guided medial retro-SCTL space block at the T4-T5 level using a mixture of 10 ml 0.5 % bupivacaine with 0.
