BACKGROUND: Several postoperative complications related to lumbar microdisectomy have been reported, including cauda equina syndrome. However, to the best of our knowledge, postoperative cauda equina syndrome resulting from dural sac shift with engorgement of the epidural venous plexus is yet to be reported. CASE DESCRIPTION: A 71-year-old male patient was referred to our hospital with a chief complaint of pain and sensory disturbance due to the lumbar disc herniation of L5-S1...

Hydatidosis, caused by Echinococcus granulosus, affects the spinal column in 0.5-2% of all cases, with the sacral column being a rare location typically observed only in adults. The case is reported of a 14-year-old boy from Juliaca (Puno, Peru) who presented with chronic lower back pain and cauda equina syndrome. He was initially attended to in Juliaca, and then transferred to the Hospital Edgardo Rebagliati Martins (Lima, Peru) with a diagnosis of sacral tumor. In magnetic resonance imaging, a multicystic tumor was seen with L5 and S1 lysis and instability...

Dong Gyu Lee, Sang Gyu Kwak, Min Cheol Chang
The evaluation of the electrically induced bulbocavernosus reflex (BCR) using electromyography (EMG) is a useful tool for evaluating the integrity of sacral spinal segments 2 to 4, and that of their afferent and efferent connections in the urogenital region. In the current retrospective study, the value of this technique in predicting the outcome of bladder dysfunction was investigated in patients with cauda equina syndrome (CES). Electrically induced BCR (E-BCR) was evaluated in 40 patients with bladder dysfunction due to CES at the subacute stage (7-90 days)...

STUDY DESIGN: A systematic review. OBJECTIVES: Conus medullaris syndrome (CMS) and cauda equina syndrome (CES) are well-known neurological entities. It is assumed that these syndromes are different regarding neurological and functional prognosis. However, literature concerning spinal trauma is ambiguous about the exact definition of the syndromes. METHODS: A MEDLINE, EMBASE and Cochrane literature search was performed. We included original articles in which clinical descriptions of CMS and/or CES were mentioned in patients following trauma to the thoracolumbar spine...

OBJECTIVE: Elsberg syndrome (ES) is an established but often unrecognized cause of acute lumbosacral radiculitis with myelitis related to recent herpes virus infection. We defined ES, determined its frequency in patients with cauda equina syndrome (CES) with myelitis, and evaluated its clinical, radiologic, and microbiologic features and outcomes. METHODS: We searched the Mayo Clinic medical records for ES and subsequently for combinations of index terms to identify patients with suspected CES and myelitis...

Intradural spinal arachnoid cysts (ISACs) have been reported in the current literature as either an idiopathic disease or exceedingly rare sequelae after lumbar puncture, spinal trauma, or meningitis. Other studies have more appropriately termed the iatrogenic pathology as a spinal subdural extra-arachnoid hygroma (SSEH), as there is not often a clear cyst wall as in a true arachnoid cyst. However, to the best of our knowledge, none of the previous studies described an SSEH following uncomplicated posterior lumbar surgery, as they have previously involved clear durotomies during the initial operation...

PURPOSE: Arteriovenous fistula (AVF) of the cauda equina (CE) fed by the proximal radicular artery (PRA) is very rare, and the differentiation from that of the filum terminale (FT) is important to avoid treatment-related injury to the CE when endovascular treatment is selected. The authors describe a case of AVF of the CE fed by the PRA, demonstrate the anatomical features and discuss the treatment precautions. METHODS: A 69-year-old man presented with a transient weakness of lower limbs...

Spinal nerve sheath tumors are well known to typically originate from dorsal sensory nerve roots. However, it is difficult to anatomically identify the origin in the case of cauda equina tumors. In this study, we aimed to ascertain whether a cauda equina nerve root removed with a nerve sheath tumor was a motor nerve using acetylcholinesterase (AchE) staining. Nerve rootlet sections removed with tumors were stained for AchE using the AchE Rapid Staining Kit. Additionally, we performed intraoperative motor-evoked potential (MEP) monitoring following either transcranial electrical stimulation (TES) or electrical stimulation of nerve rootlets...

Neurocysticercosis (NCC) is a common parasitic infection of the central nervous system but isolated primary spinal NCC is of very rare occurrence. The authors report a case of 44-year-old male, a postoperative case of multiple spinal NCC lesion excision 2 years ago, who presented with cauda equina syndrome and magnetic resonance imaging revealed a lesion mimicking an arachnoid cyst in the D1-9 region of the spinal cord. On intraoperative surgical exposure multiple cysts were found and excised. The suspicion of recurrence of NCC was confirmed by histopathology...

Cauda equina syndrome (CES) is a surgical emergency requiring urgent spinal decompression. Our objective is to analyze the association between race and in-hospital outcomes (complications, mortality, length of stay, and discharge disposition) in patients with CES. This is a retrospective cohort study of CES patients identified via the Nationwide Inpatient Sample (NIS) from 2000 to 2010 in inpatient hospitalizations in the USA. The patient sample includes 46,017 patients ≥18 undergoing spine surgery for CES...

BACKGROUND: Cauda equina syndrome (CES) is a rare neurologic complication of lumbar herniated disc for which emergency surgical decompression should be undertaken. Despite the common belief that the restoration of functions that are affected by CES can take several years postoperatively, follow up seldom exceeds the first year after surgery. Long term outcome of especially micturition, defecation and sexual function-which are by definition affected in CES-are unknown. The aim of this study is to evaluate 1) postoperative long term outcome of micturition, defecation and sexual function in CES patients 2) attitude of patients towards received hospital care with regard to (recovery of) these functions...

OBJECTIVES: Long-term lower motor neuron denervation of skeletal muscle is known to result in degeneration of muscle with replacement by adipose and fibrotic tissues. However, long-term survival of a subset of skeletal myofibers also occurs. METHODS: We performed transverse and longitudinal studies of patients with spinal cord injury (SCI), patients specifically complete Conus and Cauda Equina Syndrome and also of active and sedentary seniors which included analyses of muscle biopsies from the quadriceps m...

Here, we describe the superficial appearance of the brain of the rarely studied tree pangolin. Phylogenetic analyses have placed the pangolins, order Pholidota, as a sister group to the order Carnivora. The majority of features visible on the surface of the tree pangolin brain, and its overall appearance can be described as typically mammalian. The pattern of sulci and gyri, while simple, appears very similar to that observed in carnivores. Two derived features of the Pholidota were observed, the first being the rostral decussation of the pyramidal tract, which instead of occurring at the spinomedullary junction, decussates at the level of the caudal pole of the facial nerve nucleus in the rostral medulla oblongata...

RATIONALE AND OBJECTIVES: Emergency department (ED) patients with acute low back pain (LBP) may present with ambiguous clinical findings that pose diagnostic challenges to exclude cauda equina syndrome (CES). As a proof of concept, we aimed to determine the efficacy of a rapid lumbar spine (LS) magnetic resonance imaging (MRI) screening protocol consisting of a single 3D-T2 SPACE FS (3D-T2 Sampling Perfection with Application optimized Contrasts using different flip angle Evolution fat saturated) sequence relative to conventional LS MRI to exclude emergently treatable pathologies in this complex patient population...

RATIONALE: Burst fractures in thoracolumbar and lumbar spine typically occur from severe trauma, which may result in cauda equina herniation (CEH). In this study, we attempted to document the incidence and evaluate the sequelae of CEH that were found during decompression and fusion surgery for patients with burst fractures. PATIENT CONCERNS: A total of 416 patients were enrolled in this study. DIAGNOSES: The patients had been operated on through an anterior or posterior approach for treatments of thoracolumbar and lumbar burst fractures at our department between June 1, 2008 and June 1, 2011...

The objective of this retrospective case analysis was to evaluate the surgical impact on neurological functional recovery in cases of solitary spinal nerve sheath tumors (NSTs) originating around the epiconus, conus medullaris, or cauda equina and not associated with neurofibromatosis. This 10-year surgical study included 30 cases of spinal NSTs originating around the spine level of T12-L1 (epiconus-to-conus medullaris: Epi-CM group), and 15 cases of spinal NSTs originating below the spine level of L2 (cauda equina: CE group)...
