Neurophysiological testing of the pelvic floor is recognized as an essential tool to identify pathophysiological mechanisms of pelvic floor disorders, support clinical diagnosis, and aid in therapeutic decisions. Nevertheless, the diagnostic value of these tests in specific neurological diseases of the pelvic floor is not completely clarified. Seeking to fill this gap, the members of the Neurophysiology of the Pelvic Floor Study Group of the Italian Clinical Neurophysiology Society performed a systematic review of the literature to gather available evidence for and against the utility of neurophysiological tests...

Jung Hyun Park, Jong Yeol Kim
Spinal subarachnoid hematoma (SSH) following diagnostic lumbar puncture is very rare. Generally, SSH is more likely to occur when the patient has coagulopathy or is undergoing anticoagulant therapy. Unlike the usual complications, such as headache, dizziness, and back pain at the needle puncture site, SSH may result in permanent neurologic deficits if not properly treated within a short period of time. An otherwise healthy 43-year-old female with no predisposing factors presented with fever and headache. Diagnostic lumbar puncture was performed under suspicion of acute meningitis...

A 73-year-old man who presented with right lumbosciatic pain underwent a neurosurgical operation for a voluminous L2-L3 disc herniation, seen on conventional MRI images. No disc herniation was identified in the epidural space during the surgery. Just after the operation, the patient started to present pain in the left L3 territory and was not able to walk any more. A second MRI including three-dimensional (3D) high-resolution constructive interference in steady state (CISS) sequence showed that the voluminous L2-L3 disc split the posterior longitudinal ligament and the anterior dura mater, extended intradurally and compressed the cauda equina to the right...

We investigated the relationship between the involvement of the cauda equina in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and the increment of cerebrospinal fluid (CSF) protein. We measured cauda equina conduction time (CECT) in 14 CIDP patients using magnetic stimulation with a MATS coil. Statistical analysis revealed that CECT and CSF protein had a significant positive linear correlation. Conduction time of the peripheral nerve trunk, in contrast, had no significant linear correlation with CSF protein...

When a dural defect is encountered during spine surgery, the dura mater must be reconstituted to minimize the occurrence of minor or major life-threatening sequelae. The neurosurgical literature lacks strategies for managing large dural defects encountered during surgery. The authors describe a 24-year-old man who developed cauda equina syndrome secondary to altered CSF flow in a large thoracolumbar arachnoid cyst. Surgical decompression and fenestration of the arachnoid cyst were performed, and the large dural defect was treated using a multilayer closure with collagen matrix, titanium mesh, and methylmethacrylate...

OBJECTIVE Myxopapillary ependymoma is a benign WHO Grade I tumor most commonly located in the conus-cauda equina region of the spine. Although this tumor is defined by an overall excellent survival, dissemination throughout the whole neuraxis occurs frequently. The current study evaluated the clinical characteristics and significance of myxopapillary ependymoma metastases. METHODS Patients who underwent surgery from 2005 to 2015 for treatment of spinal myxopapillary ependymoma were included in the study. Charts were reviewed for primary tumor symptoms and initial treatment, local recurrence, response to salvage therapy, and presence and behavior of distant metastases...

BACKGROUND AND IMPORTANCE: Endovascular therapy has proven to be a safe, minimally invasive treatment for multiple etiologies, but proper precautions must be taken to avoid complications. When complications occur, they should be promptly identified and corrected when possible. This case report describes endovascular stents misplaced into the epidural spinous venous plexus rather than the iliofemoral arteries, causing cauda equina syndrome, as well as the spinal procedure performed to treat the resulting spinal canal compression...

BACKGROUND: Previous studies have shown similar clinical outcomes of both single and multi-fraction (Fr) radiation therapy among malignant epidural spinal cord compression (MSCC) patients with poor prognosis; whereas, patients expected to have longer survival may require long-course radiotherapy to prevent local failure. However, such a poor prognosis risk group has not yet been clearly identified for use in daily clinical practice. We examined if the known predictive Tokuhashi scoring system could be adapted in MSCC patients treated with palliative radiation therapy...

Background/aim: Upper lumbar disc herniation (LDH), generally involving L1?L2 and L2?L3 level herniation, is less common than lower LDH and, in this retrospective study, the clinical and radiological findings of patients who suffered from upper LDH and were operated on due to this pathology were reviewed. Materials and methods: Data regarding neurological and radiological findings of patients operated on between January 2005 and December 2013 were retrospectively collected. During this period, 3494 patients had surgery for LDH, and 129 of these patients had disc herniation at the upper levels...

The transforaminal lumbar interbody fusion (TLIF) is used for the treatment of back and leg pain secondary to spinal stenosis, degenerative disc disease, and spondylolisthesis. Minimally invasive surgery (MIS) is associated with less estimated blood loss (EBL), decreased length of stay, lower infection rates, and similar outcomes compared to the traditional TLIF. Fluoroscopy time has been reported with MIS-TLIF, but there are limited data on specific radiation dosages. We performed a retrospective analysis of a prospectively acquired cohort of patients undergoing MIS-TLIF...

Background: In the lumbar spine, degenerative spondylolisthesis or degenerative (not traumatic) slippage of one vertebral body over another is divided into 4 grades - grade I (25%), grade II (50%), grade III (75%), and grade IV (100%). Dynamic X-rays, magnetic resonance (MR), and computed tomography (CT) scans document the slip secondary to arthritic changes of the facet joint plus stenosis, ossification of the yellow ligament, disc herniations, and synovial cysts. MR best demonstrates soft tissue pathology whereas CT better delineates ossific/calcified disease...

Studies show that spinal (intrathecal; i.t.) interleukin-10 (IL-10) gene therapy reverses neuropathic pain in animal models, and co-administration with the mannose receptor (MR; CD206) ligand d-mannose (DM) greatly improves therapeutic efficacy. However, the actions of endogenous IL-10 may be required for enduring pain control observed following i.t. IL-10 gene therapy, potentially narrowing the application of this non-viral transgene delivery approach. Here, we show that i.t. application of naked plasmid DNA expressing the IL-10 transgene co-injected with DM (DM/pDNA-IL-10) for the treatment of peripheral neuropathic pain in IL-10 deficient (IL-10 KO) mice results in a profound and prolonged bilateral pain suppression...

BACKGROUND: The purpose of this case report is to present a rare finding of an intradural extramedullary hemangioblastoma of the cauda equina, with literature review. Spinal hemangioblastomas account for 1-5% of all spinal cord tumors. While spinal hemangioblastomas are rare, it is exceedingly rare to have a case of intradural extramedullary hemangioblastoma of the spine, especially in isolation without von-Hippel-Lindau syndrome. Only 20 previous cases have been reported. CASE DESCRIPTION: An 82-year-old male presented with MRI evidence of an intradural mass at the L4 spinal level...

Objective: The purpose of this case report is to describe the diagnostic imaging features of redundant nerve roots caused by chronic lumbar degenerative canal stenosis (CLDCS). Clinical Features: A 56-year-old male presented with severe low back pain. He experienced pain during minimal active lumbar range of motion. The patient demonstrated weakness of the right iliopsoas and hypoesthesia of the L-2 dermatome. A working diagnosis of CLDCS was established. The patient's worsening severe low back pain warranted magnetic resonance imaging of the lumbar spine, which was performed for further evaluation...

Intervertebral disc prolapse is a common cause of both acute and chronic low back pain. This can result in differential grades of motor and sensory disturbances in lower limbs and even cauda equina syndrome (CES). The neurological manifestations are a result of compression of the spinal cord and roots ventrally in the spinal canal due to the prolapsed disc. However, neurologic deficits owing to compression of the spinal cord dorsally as a result of migration of sequestrated disc fragments are very rare. We present two different cases of back pain with severe neurologic deficit referred to us within a short span of one month...

Background • Large intervertebral disc herniation is often managed with surgery, but it is not uncommon for spontaneous resorption of herniated disc material to occur. Although the majority of spontaneous disc resorption occurs in the acute phase, an unusual case of delayed intervertebral disc regression at 18 mo postonset is presented. Case Presentation • A 32-y-old female patient presented with acute low-back pain and pain in both legs a Korean medicine hospital specializing in spinal disorders. Massive intervertebral disc herniation was found on lumbar magnetic resonance imaging (MRI), and inguinal and genital pain and numbness was suggestive of risk of cauda equina syndrome...
