Si-Dong Yang, Qian Chen, Wen-Yuan Ding
Cauda equina syndrome (CES) resulting from acute lumbar disc herniation due to spinal massage is extremely rare. We present a case of CES caused by the acute worsening of a lumbar disc herniation after a vigorous back massage that included spinal manipulation. After vigorous back massage with spinal manipulation performed by a massage therapist, a 38-yr-old male patient experienced CES with severe numbness in both lower limbs, inability to walk due to weakness of bilateral lower limbs, and incontinence of urine and feces...

BACKGROUND: The lumbar spine includes 5 lumbar vertebral bodies, L1, L2, L3, L4, and L5. At each level, there is a disc space defined by the two bones (vertebral bodies) in the back; for example, there is a disc space at the L5-S1 level etc. The normal front to back (anterior to posterior or AP diameter) measurement of the spinal canal is typically 18-20 mm, but some patients have narrowing called spinal stenosis. METHODS: Lumbar stenosis is defined by two major types...

INTRODUCTION: Spinal bronchogenic cysts are rare findings, with only four cases of lumbar bronchogenic cysts reported in the literature. All of these bronchogenic cysts involved the conus medullaris. We present the first case of a lumbar bronchogenic cyst and arachnoid cyst arising from the cauda equina in a 68-year-old male. Uniquely, this bronchogenic cyst also contained components of an arachnoid cyst. METHODS: Magnetic resonance imaging (MRI) demonstrated a compressive cystic lesion at the level of the L3 vertebra splaying the cauda equina...

An 8-year-old spayed female border collie dog was diagnosed with an invasive pituitary macrotumor. Five months after radiation therapy, the patient developed paraparesis and lumbosacral pain. Necropsy revealed a pituitary carcinoma with cauda equina drop metastasis. In cases of pituitary masses, meningeal dissemination should be considered if neurologic status declines.

BACKGROUND CONTEXT: Although lumbar disc herniations are common, only a small portion of these herniations lead to cauda equina syndrome (CES) which is an uncommon but debilitating disorder. Why some patients with herniation develop CES, when most do not, remains unknown. Pre-existing subclinical epidural lipomatosis may limit canal space such that an otherwise benign herniation causes CES. PURPOSE: This study determines whether patients with an acute disc herniation and CES have a greater body mass index (BMI) and greater quantity of epidural fat compared to control subjects with non-CES symptomatic lumbar herniated discs...

BACKGROUND The differences between the peripheral and central branches of the dorsal root ganglion (DRG) have not been fully elucidated. This study aimed to explore the expression of tubulin post-translational modifications (acetylation and deacetylation) between damaged peripheral and central branches of DRG neurons. MATERIAL AND METHODS Fifty Sprague-Dawley rats were randomly assigned to five groups with 10 rats in each group. These five groups consisted of spinal nerve ligation (SNL) at 24 hour and 48 hour, and cauda equina compression (CEC) at 24 hour and 48 hour, and a sham group...

INTRODUCTION: Treatments for patients with cauda equina injury are limited. METHODS: In this study, we first used retrograde labeling to determine the relative contributions of cauda equina motor neurons to intrinsic and extrinsic rat tail muscles. Next, we transected cauda equina ventral roots and proceeded to bridge the proximal and distal stumps with either a type I collagen scaffold coated in laminin (CL) or a collagen-laminin scaffold that was also seeded with Schwann cells (CLSC)...

BACKGROUND: The incidence of tertiary syphilis involvement in the spinal column with destructive bone lesions is very rare. It is difficult to establish the correct diagnosis from radiographs and histological examination alone. Limited data are available on surgical treatment to tertiary syphilitic spinal lesions. In this article, we report a case of tertiary syphilis in the lumbar spine with osteolytic lesions causing cauda equina compression. CASE PRESENTATION: A 44-year-old man who suffered with low back pain for 6 months and progressive radiating pain at lower extremity for 1 week...

Purpose: The filum terminale (FT) is a fibrous band that connects the conus medullaris to the posterior body of the coccyx. Considering the advances of ultrasonography (US) technology and improvements in the resolution of US images, we aimed to re-establish the US features of the normal FT in infants younger than 6 months of age. Methods: We retrospectively reviewed 30 spinal US scans, stored as video clips. The internal structure of the FT and the marginal echogenicity of the FT were assessed, and transverse and longitudinal US were compared...

BACKGROUND: Juxtafacet spinal cysts are cystic synovial lesions that are often indistinguishable clinically or radiologically and require histopathology analysis to confirm the diagnosis. Lumbar synovial cysts usually arising from the synovium of the facet joints. They have been described posterolateral or rarely in the posterior midline. However, we describe the first synovial cyst ventral to the dural sac. CASE DESCRIPTION: We report a lumbar 3-4 lesion causing cauda equina compression in a 57-year-old man who presented with 3 months history of low back pain and bilateral sciatica, intermittent urinary incontinence and erectile dysfunction...

H-type bovine spongiform encephalopathy (H-BSE) is an atypical form of BSE in cattle. During passaging of H-BSE in transgenic bovinized (TgBoPrP) mice, a novel phenotype of BSE, termed BSE-SW emerged and was characterized by a short incubation time and host weight loss. To investigate the biological and biochemical properties of the BSE-SW prion, a transmission study was conducted in cattle, which were inoculated intracerebrally with brain homogenate from BSE-SW-infected TgBoPrP mice. The disease incubation period was approximately 15 months...

BACKGROUND: Pedicle screw fixation in high grade lumbar listhetic vertebral body has been nightmare for Orthopaedic and spine surgeons. This is because of abnormally positioned listhetic pedicles and non-visualization of pedicle in conventional image intensifier (C-Arm). This results into increased surgical time, more blood loss, radiation exposure and more chances of infection. To overcome this problem, we have devised a new Technique of putting of pedicle screw fixation in listhetic vertebrae...

BACKGROUND: Spinal anaesthesia is technique of choice for caesarean sections and hyperbaric bupivacaine is a recommended drug for this popular block. Although safe but few complications are haemodynamic changes, postdural puncture headache, cauda equina syndrome and radiculopathy. However, hypotension remains the common side effect which is believed to occur in 95% of patients resulting in reduction of uteroplacental perfusion causing foetal acid-base abnormalities. Various doses regimes are in safe anaesthesia practice for providing regional anaesthesia for such patients with least detrimental effects on foetal outcome...

There is a lack of information and consensus regarding the optimal treatment for recurrent disc herniation previously treated by posterior discectomy, and no reports have described an anterior approach for recurrent disc herniation causing cauda equina syndrome (CES). Revision posterior decompression, irrespective of the presence of CES, has been reported to be associated with significantly higher rates of dural tears, hematomas, and iatrogenic nerve root damage. The authors describe treatment and outcomes in 3 consecutive cases of patients who underwent anterior lumbar discectomy and fusion (ALDF) for CES caused by recurrent disc herniations that had been previously treated with posterior discectomy...

BACKGROUND CONTEXT: We receive a large number of patients with spinal cord injury (SCI) due to penetrating gunshot wounds (GSW) at our national rehabilitation center. Although many patients are labeled American Spinal Injury Association (ASIA) B sensory incomplete because of sensory sparing, especially deep anal pressure, with purported prognostic value, we have not observed a clinical difference from patients labeled ASIA A complete. We hypothesized that sensory sparing, if meaningful, should reduce the occurrence of pressure ulcers...

BACKGROUND: Carcinoid tumors are neuroendocrine neoplasms derived from enterochromaffin cells. Central nervous system involvement is rare. The reported cases include metastases to brain or spinal cord, as well as primary skeletal or extradural disease resulting in compressive myelo-radiculopathy. There are two previously reported cases of primary intradural extramedullary carcinoid tumor, presenting with compressive symptoms. We report the first case of primary incidental intradural extramedullary carcinoid tumor...

REVIEW
Nicholas Elkins, Jason Hunt, Kelly M Scott
Pelvic neuralgias frequently cause severe pain and may have associated bladder, bowel, or sexual dysfunctions which also impact quality of life. This article explores the etiology, epidemiology, presentation and treatment of common causes of neurogenic pelvic pain, including neuralgia of the border nerves (ilioinguinal, iliohypogastric, and genitofemoral), pudendal neuralgia, clunealgia, sacral radiculopathies caused by Tarlov cysts, and cauda equina syndrome. Treatment of pelvic neuralgia includes conservative measures such as pelvic physical therapy, lifestyle modification, and medications with escalation to more invasive and novel treatments such as nerve blocks, radiofrequency ablation, cryoablation, neuromodulation and neurectomy/neurolysis if conservative treatments are ineffective...
