Brown-Séquard Syndrome (BSS) is a rare form of incomplete spinal cord injury and is characterized by ipsilateral motor deficit and contralateral sensory loss. BSS is commonly associated with traumatic etiologies, but non-traumatic causes should be considered as well. A 38-year-old woman presented with a 3-week history of weakness in her right upper extremity, and she has developed numbness and tingling in her left upper and lower extremities over the past week and a half, along with some motor difficulty. Imaging showed a large right paracentral disc protrusion at the C3-C4 level causing severe spinal canal narrowing and resulting in abnormal cord signal. The patient subsequently underwent a C3-4 cervical total disk replacement. Hemovac placed during surgery was removed on post-op day one, and she was re-evaluated by PT/OT and recommended for outpatient therapies on post-op day two. Our case, along with a review of the literature, highlights those non-traumatic causes of BSS should be considered as a cause of BSS. BSS produced by a herniated cervical disc is extremely rare and is often misdiagnosed., Competing Interests: Declaration of competing interest The authors do not have a financial interest or relationship to disclose regarding this research project., (Copyright © 2024 Elsevier Inc.

Introduction: Acute transverse myelitis (ATM) refers to a rare severe acquired spinal cord inflammation, with a challenging diagnostic work-up and treatment., Case Presentation: We report the case of a 42-year-old patient who presented with loss of temperature and pain sensation beneath the C5 dermatome in her left side and reported a history of a possible respiratory tract illness 10 days ago. Within 2 days, clinical worsening was noted, compatible with Brown-Sequard syndrome. Spinal magnetic resonance imaging revealed a T2 sequence abnormal signal from level C4 to T3 and cerebrospinal fluid (CSF) studies showed only a mild pleocytosis mononuclear type. Extensive CSF and blood tests revealed only high Mycoplasma pneumoniae IgM and IgG titers. Treatment with high-dose intravenous methylprednisolone and oral azithromycin were administrated and the patient recovered completely within two months., Discussion: We would like to highlight the importance for physicians to consider M. pneumoniae in their differential diagnosis as a potential cause when encountering patients with symptoms of ATM and inflammatory Brown-Sequard syndrome., (© 2024.

Brown-Séquard syndrome refers to a set of signs and symptoms caused by hemisection of the spinal cord from various sources. It may have multiple causes; traumatic injuries are the most frequent ones. The less common causes include inflammation, ischemia, tumors, or infections. This report is about a 12-year-old boy with an acute and progressive course of right hemisection of the spinal cord, with ipsilateral hypo/areflexic paralysis and contralateral loss of thermalgesic sensation. The MRI of the spinal cord showed inflammation in the right side of the spinal cord at the level of the second and third thoracic vertebrae. The patient was diagnosed with idiopathic transverse myelitis and was started on intravenous high-dose corticosteroids; he showed a favorable clinical course and recovered neurological functions., (Sociedad Argentina de Pediatría.)

Background: Thoracic disc herniation is relatively uncommon, accounting for less than 1% of all spinal herniations. Although most often asymptomatic, they may represent a rare cause of spinal cord ischemia., Case Report: We report the case of a healthy 43-year-old North African male who presented with a Brown-Sequard syndrome revealing a spinal cord ischemia caused by a thoracic disc extrusion. The initial MRI revealed a calcified disc extrusion at the level of T5-T6 without significant spinal cord compression or signal abnormality. A pattern consistent with a medullary ischemia only appeared 48 h later. The patient was treated conservatively with Aspirin and Heparin, which were discontinued later because of a negative cardiovascular work-up. The calcified disc extrusion, which was later recognized as the cause of the ischemia, decreased spontaneously over time and the patient recovered within a few months., Conclusions: Our case highlights the challenge in diagnosing and managing this uncommon condition. We propose a literature review showing the different therapeutic strategies and their corresponding clinical outcomes., (© 2023. The Author(s).)

Context: Brown-Séquard Syndrome (BSS) is a rare neurological condition associated with Spinal Cord Injury (SCI). Hemisection of the spinal cord causes paralysis of the homolateral side, and thermoalgesic dysfunction on the opposite side. Cardiopulmonary and metabolic alterations have been reported. For all these patients, regular physical activity is highly recommended and functional electrical stimulation (FES) may be a good option, especially for those with paraplegia. However, to our knowledge, the effects of FES have primarily been studied in those with complete SCI and data regarding application and effects in patients with incomplete lesions (with sensory feedback) is lacking. The present case report therefore evaluated the feasibility and effectiveness of a 3-month FES-rowing program in a patient with BSS., Methods: Knee extensor muscle strength and thickness, walking and rowing capacities as well as quality of life were evaluated before and after 3 months of FES-rowing (two sessions per week) in a 54 year old patient with BSS., Results: The individual had excellent tolerance and adherence to the training protocol. All measured parameters were greatly improved after 3 months: on average, + 30% rowing capacity, + 26% walking capacity, + 24.5% isometric strength, + 21.9% quadriceps muscle thickness, + 34.5% quality of life., Conclusion: FES-rowing appears to be well tolerated and highly beneficial for a patient with incomplete SCI and could therefore be considered as an appealing exercise option for these patients.

Acute myelitis encompasses syndromes associated with inflammation of the spinal cord. In cases of inflammatory lesions that only involve a unilateral portion of the axial plane of the cord, Brown-Séquard syndrome may occur, resulting in potential ipsilateral corticospinal, dorsal spinocerebellar, or dorsal column dysfunction or contralateral spinothalamic dysfunction below the level of the lesion. We report a case of an adult male who presented with Brown-Séquard syndrome and with a positive SARS-CoV-2 nasopharyngeal swab PCR test. Neurological symptoms rapidly resolved after initiation of high-dose methylprednisolone. The findings reported not only contribute to documenting a new presentation of neurological complications associated with SARS-CoV-2 infection but also non-exclusively supports the body of literature suggesting the immune-mediated response to this infection as a mechanism of neuropathogenesis. In this case, COVID-19-related acute myelitis responded to treatment with a short regimen of high-dose glucocorticoids., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2023.

Background: There are some cases of Klippel-Feil syndrome with spinal cord injury in clinical work. However, there is no literature report on Brown-Sequard syndrome after trauma. We report a case of Brown-Sequard syndrome following minor trauma in a patient with KFS type III. Her Brown-Sequard syndrome is caused by Klippel-Feil syndrome., Case Presentation: We found a 38-year-old female patient with KFS in our clinical work. She was unconscious on the spot following a minor traumatic episode. After treatment, her whole body was numb and limb activity was limited. Half an hour later, she felt numb and weak in the right limb and weak in the left limb. She had no previous hypertension, diabetes, or coronary heart disease. After one-month treatment of medication, hyperbaric oxygen, rehabilitation, and acupuncture in our hospital, her muscle strength partially recovered, but the treatment effect was still not satisfactory. Then, she underwent surgical treatment and postoperative comprehensive treatment, and rehabilitation training. She was able to take care of herself with assistance, and her condition improved from grade B to grade D according to the ASIA (ASIA Impairment Scale) classification., Conclusion: KFS, also known as short neck deformity, is a kind of congenital deformity characterized by impaired formation and faulty segmentation of the cervical spine, often associated with abnormalities of other organs. The cervical deformity in patients with KFS can alter the overall mechanical activity of the spine, as well as the compensatory properties of the spine for decelerating and rotatory forces, thus increasing the chance of spinal cord injury (SCI) following trauma. Many mechanisms can make patients more susceptible to injury. Increased range of motion of the segment adjacent to the fused vertebral body may lead to slippage of the adjacent vertebral body and altered disc stress, as well as cervical instability. SCI can result in complete or incomplete impairment of motor, sensory and autonomic nervous functions below the level of lesion. This woman presented with symptoms of BSS, a rare neurological disorder with incomplete SCI. Judging from the woman's symptoms, we concluded that previously she had KFS, which resulted in SCI without fracture and dislocation following minor trauma, with partial BSS. After the comprehensive treatment of surgery, hyperbaric oxygen, rehabilitation therapy, and neurotrophic drugs, two years later, we found her symptoms significantly improved, with ASIA Impairment Scale from grade B to grade D, and her ability to perform activities of daily living with aids., (© 2023.

A 50-year-old man was referred to our hospital with myelitis associated with a 10-months history of progressive muscle weakness in the left leg. Neurological examinations demonstrated diffuse muscle weakness of the left leg, touch hypoesthesia of the right leg, reduced pain sensation below the right nipple, left pyramidal sign, and urinary incontinence. On the basis of thoracic spinal MRI and thoracic CT myelography, revealing anterior displacement of the spinal cord and enlargement of the posterior subarachnoid space at the Th4 vertebral level, we diagnosed the patient as having idiopathic spinal cord herniation with incomplete Brown-Séquard syndrome. After microsurgical release of the spinal cord and subsequent covering of the anterior dural defect with an artificial dura mater, the symptoms improved without progression. Clinicians should consider spinal cord herniation as a cause of slowly progressive thoracic myelopathy with Brown-Séquard syndrome.

Brown-Séquard syndrome (BSS) has many etiologies, including penetrating trauma, extramedullary tumors, and disc herniation. However, thoracic ossification of the ligamentum flavum (OLF) is an extremely rare cause of this syndrome. A 46-year-old woman with motor weakness in her right lower extremity and urinary retention was admitted to our department. Based on the results of physical examination, computed tomography, and magnetic resonance imaging, a diagnosis of BSS with OLF was considered. The patient underwent urgent conservative treatment. BSS is a rare condition characterized by hemisection or hemicompression of the spinal marrow. The herein-described case of incomplete BSS due to OLF responded to conservative treatment. However, the successful nonoperative management of this case is insufficient evidence to consider it as the standard of care. Therefore, emergency laminectomy decompression remains the standard of care for BSS.

Introduction: Spinal cord injury after manual manipulation of the cervical spine is rare and has never been described resulting from a patient performing a manual manipulation on their own cervical spine. To the best of our knowledge, this is the first well-documented case of this association., Case Presentation: A healthy 29-year-old man developed Brown-Sequard syndrome immediately after performing a manipulation on his own cervical spine. Imaging showed large disc herniations at the levels of C4-C5 and C5-C6 with severe cord compression, so the patient underwent emergent surgical decompression. He was discharged to an acute rehabilitation hospital, where he made a full functional recovery by postoperative day 8., Conclusion: This case highlights the benefit of swift surgical intervention followed by intensive inpatient rehab. It also serves as a warning for those who perform self-cervical manipulation., (© 2022. The Author(s), under exclusive licence to International Spinal Cord Society.)

SCIWORA (Spinal Cord Injury without Radiologic Abnormality) is a rare condition that mainly affects pediatric patients; We present the case of a teenage male patient diagnosed with SCIWORA/Brown Séquard Syndrome. In admission, he has multiple bruises on his neck and right hemibody and immediately he refers paraesthesia in all four limbs and spastic hemiparesis with right predominance, as well as inability to stand up and urinary continence. Treatment based on NASCIS III study is initiated and after the imaging tests, a diagnosis has already been made. We present the most current definitions of SCIWORA and the recommendations to make its diagnosis, as well as its relationship and coexistence with spinal syndromes.

BACKGROUND Traumatic spinal cord injuries are quite common; however, a rare form of incomplete spinal cord injury is Brown-Sequard syndrome. Brown-Sequard syndrome is defined by the National Institute of Neurological Disorders and Strokes as "a rare neurological condition characterized by a lesion in the spinal cord which results in weakness or paralysis (hemiparaplegia) on one side of the body and a loss of sensation (hemianesthesia) on the opposite side." CASE REPORT A 33-year-old man was brought to the Emergency Department by Saudi Red Crescent with multiple stab wounds on the left upper thoracic and lower cervical regions. He was tachycardic, but otherwise vitally stable. His Glasgow Coma Scale score was 15. The patient presented with bilateral lower limb weakness, more on the ipsilateral (left) side, and contralateral (right) hypoesthesia from the level of the nipple below. Cervical and thoracic magnetic resonance imaging revealed ligamentous injury defect at the posterior dura and indicating a dural tear with minor cerebrospinal fluid leak. Focal hyperintense signal intensity was noted on the left side of the spinal cord, representing contusion. The patient was managed conservatively with daily physical therapy. Strength had improved substantially by the time of discharge and sensation was improving. CONCLUSIONS Brown-Sequard syndrome is associated with good prognosis. These patients require a multidisciplinary approach because it provides the best chance of recovery to pre-injury status. These injuries may cause disastrous neurological deficits; therefore, preventive strategies should be designated to decrease the incidence of such injuries.

Objective: This study aims to describe the clinical characteristics of patients with sulcal artery syndrome, and between those with vertebral artery dissection against those without., Methods: We report three cases of sulcal artery syndrome without vertebral artery dissection, performed a systematic review and retrospective analysis of the characteristics of patients with sulcal artery syndrome in available literature, and compared the clinical features of those with vertebral artery dissection against those without., Results: We report 3 patients with sulcal artery syndrome, and analysed them with 17 other cases identified in literature between January 1990 till April 2020. The mean age was 47 years (range 10-80), with twice as many males as females. Pain at onset was a prominent feature (17/18, 94.4%). Preceding trauma occurred in less than half (7/18, 38.9%). Most had cervical cord infarctions (18/20, 90%), often over the high cervical cord (16/18, 88.9%). Good functional recovery (mRS 0-2) was observed in 86.7% (13/15). While vertebral artery dissection was the leading aetiology (11/20, 55.5%), about half of the cases were due to other causes. Cervical cord involvement was significantly associated with vertebral artery dissection (p = 0.026)., Conclusion: Sulcal artery syndrome should be suspected in patients with acute hemicord syndrome, especially in males with cervical cord involvement or pain at onset. High cervical cord involvement was strongly suggestive of underlying vertebral artery dissection. Additionally, DWI sequences are useful when evaluating acute myelopathies, and its inclusion in conventional MRI sequences is supported in prevailing literature., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2021 Elsevier Ltd.

Rationale: A case of traumatic atlanto-axial rotatory subluxation (AARS), dens fracture, rupture of transverse atlantal ligament (TAL), and subaxial spinal cord injury without radiographic abnormality (SCIWORA) of Brown-Sequard syndrome has never been reported in a child., Patient Concerns: A 7-year-old boy presented to hospital with torticollis, neck pain, and limited neck rotation after a seat-belt injury sustained during a car accident. Neurologic examination revealed right-side motor weakness and left-side sensory abnormality, known as Brown-Sequard syndrome., Diagnosis: Radiologic examinations revealed type II AARS (Fielding and Hawkins classification), increased atlanto-dental interval (ADI) of 4.5 mm due to a type 1B TAL rupture (Dickman classification), a displaced transverse dens fracture along with an ossiculum terminale, and an intramedullary hemorrhage on the right side of the spinal cord at C3-4., Interventions: The patient immediately received methylprednisolone, and his motor weakness and sensory abnormality gradually improved. At the same time, the patient underwent initial halter traction for 2 weeks, but he failed to achieve successful reduction and required manual reduction under general anesthesia., Outcomes: At the 7-month follow-up visit, radiologic examinations showed a corrected type II AARS that was well maintained and normalization of the ADI to 2 mm. The reduced transverse dens fracture was well maintained but still not united. All clinical symptoms were significantly improved, except the remaining motor weakness of the right upper extremity., Lessons: To the best of our knowledge, this is the first report of traumatic AARS, dens fracture, TAL rupture, and subaxial SCIWORA of Brown-Sequard syndrome in a child. Appropriate diagnosis and careful treatment strategy are required for successful management of complex cervical injuries in a child., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 the Author(s).

Brown-Séquard syndrome (BSS) presents as an ipsilateral loss of motor function, proprioception and vibratory sensation accompanied by contralateral pain and temperature loss two to three levels below the level of the injury. It is one of the syndromes associated with incomplete transection of the spinal cord. Classic BSS is rare as most patients present with mixed neurological deficits related to damage of the spinal cord and surrounding structures. BSS remains prevalent in areas with high trauma burden, where assaults with sharp weapons are common. We present the case of a man aged 38 years who sustained a stab injury to the left back. BSS was diagnosed. He underwent removal of the weapon in the operating room and had an uneventful recovery to near baseline functional level after a course of rehabilitation. Despite being a rare aetiology, BSS continues to be an excellent reminder to trauma providers of the anatomy and physiology of neuroanatomical tracts., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

Background: Spinal cord infarction (SCI) is rarely caused by vertebral artery dissection (VAD), which is an important cause of posterior circulation stroke in young and middle-aged patients. We report the case of a middle-aged patient without obvious risk factors for atherosclerosis who had SCI from right VAD., Case Presentation: An otherwise healthy 40-year-old man presented with acute right-sided body weakness. Six days earlier, he had experienced posterior neck pain without obvious inducement. Neurologic examination revealed a right Brown-Séquard syndrome. Magnetic resonance imaging (MRI) of the head was normal. Further, cervical spine MRI showed spinal cord infarction (SCI) on the right at the C1-C3 level. Three-dimensional high-resolution MRI (3D HR-MRI) volumetric isotropic turbo spin echo acquisition (VISTA) scan showed evidence of vertebral artery dissection (VAD). The patient was significantly relieved of symptoms and demonstrated negative imaging findings after therapy with anticoagulation (AC) and antiplatelets (AP) for 3 months., Conclusions: The possibility of vertebral artery dissection (VAD) should be considered in the case of young and middle-aged patients without obvious risk factors for atherosclerosis. Furthermore the VISTA black blood sequence plays an important role in the pathological diagnosis of vertebral artery stenosis. Early correct diagnosis and active therapy are crucial to the prognosis.

Background: Idiopathic spinal cord herniation is a rare condition that involves spinal cord herniation through a defect in the ventral dura., Case Description: We present a case of a 61-year-old woman who initially presented in 2016 with an approximately 1-year history of burning right lower extremity pain and gait instability. Her neurologic examination was consistent with thoracic Brown-Sequard syndrome, and spinal magnetic resonance imaging showed a focal defect in the ventral dura at the superior aspect of T4 with the left aspect of the cord herniating into the defect. In 2018, she underwent a T3-T4 laminectomy with T3 pedicle take down and medial facetectomy, with reduction of the herniated cord., Conclusions: Idiopathic spinal cord herniation is an uncommon spinal cord disorder with a paucity of data reported. Our case report of a classic case of idiopathic spinal cord herniation presenting as Brown-Sequard syndrome and managed surgically will contribute to the data in this field., (Copyright © 2019 Elsevier Inc.

Rationale: Brown-Sequard syndrome (BSS) is manifested as ipsilateral motor deficit and contralateral sensory loss. BSS caused by herniated cervical disc is extremely rare and easily be misdiagnosed, and clinical features of this problem were not fully understood., Patient Concerns: A 57-year-old man presented with a 3-month history of weakness in his right arm, and he experienced progressive right hemiparesis at 2 days before admission, along with contralateral deficit in sensation of pain and temperature below T2., Diagnoses: Magnetic Resonance Imaging (MRI) showed severe cord compression due to a large paracentral extradural C4-C5 cervical disc herniation (CDH)., Interventions: Subtotal cervical corpectomy, decompression, and fusion through anterior approach were performed. The patient recovered rapidly after surgery., Outcomes: Complete recovery of sensory and motor functions was obtained at a 4-months follow-up after surgery., Lessons: Our case, along with a review of the literature, highlights that careful medical history inquiries, detailed neurologic examinations, and cervical spinal MRI scans are essential for diagnosis of CDH caused BSS. Prompt surgical decompression according to individual condition is commonly warranted. Early diagnosis with prompt surgical decompression could lead to favorable recovery.

Cervical Traumatic SSH are very rare in literature. They are usually caused by cardiopulmonary diseases that increase vascular pressure causing spinal vessels rupture. In thoracolumbar spine, the spinal puncture is the most common cause. The ventrolateral position is even more unusual. In traumatic brain injury (TBI), an abrupt extension-flexion movement could have caused the rupture of subarachnoid vessels. This, accompanied by the slowed blood "wash out" (probably due to the previous osteoarthrosis and spinal canal stenosis), led to the formation of an organized clot, which caused an acute spinal cord compression syndrome. Cervical subarachnoid spinal hematoma can present as Brown-Séquard syndrome. The treatment is prompt surgical removal and decompression. The posterior approach (partial hemilaminectomy with or without laminoplasty) with microsurgical technique is feasible, fast and simple to evacuate the hematoma with good results. Surgical nuances in posterior approach are: small spinal canal, difficulty in mobilizing the cervical cord, these haematomas are wrapped and attached to the spinal cord or nerve roots by multiple arachnoid bands, requiring techniques of Microdissection for its evacuation unlike the epidural and subdural haematomas that are easily aspirated. Here, we report a unique case of a ventrolateral SSH due to TBI., (Copyright © 2017 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U. All rights reserved.)

Brown-Sequard syndrome is an uncommon complication of atlantoaxial arthrodesis. A 50-year-old female visited our emergency department after falling from a ladder. Radiologic evaluations revealed chronic C1-2 instability with acute spinal cord injury. The day after atlantoaxial fusion was performed, she developed left-sided motor weakness and the loss of right-sided pain and temperature sensation. Based on physical examination and radiologic findings, we diagnosed her as having Brown-Sequard syndrome. Spine surgeons performing this procedure should therefore consider Brown-Sequard syndrome if a patient displays signs of postoperative hemiplegia., (Copyright © 2017 Turkish Association of Orthopaedics and Traumatology.

Background: Spinal osteochondroma is a rare but recognized cause of myelopathy. Brown-Séquard syndrome is a form of severe myelopathy characterized by a clinical picture of hemisection of the spinal cord. Brown-Séquard syndrome caused by osteochondroma is extremely rare, calling for individualized surgical procedures., Case Description: We report a 16-year-old girl with hereditary multiple exostoses and a rare case of thoracic osteochondroma causing partial Brown-Séquard syndrome. Customized surgical procedures were designed to avoid iatrogenic spinal cord injury. The patient underwent neural decompression and tumor excision through a transpedicular approach. The surgical procedure consisted of 4 consecutive steps: 1) laminectomy, 2) costotransversectomy and pediculectomy, 3) extracavitary removal of the mass, and 4) pedicular fixation with fusion. Total resection of the tumor was achieved macroscopically without intraoperative spinal cord injury. The postoperative recovery was uneventful, and the patient returned to a normal life without evidence of recurrence at 24-month follow-up., Conclusions: For patients with hereditary multiple exostosis and new onset of neurologic symptoms, the possibility of a spinal osteochondroma should be considered. In the situation of an intraspinal exostosis protruding from the lateral side, customized surgical procedures with a transpedicular approach may be a valid way to minimize intraoperative neural injury and achieve a satisfactory outcome., (Copyright © 2017 Elsevier Inc.

Background: Use of distal nerve transfer for improving upper limb function has been well described for patients with tetraplegic spinal cord injury and brachial plexus injuries but has not previously been described for Brown-Séquard type spinal cord injury. We describe our experience with 2 cases of combined Brown-Séquard injury and unilateral brachial amyotrophy., Case Description: Patient 1, a 43-year-old woman, was involved in a motor vehicle accident and sustained left-side C5-7 level hemicord injury causing ipsilateral proximal arm weakness and sensory loss with contralateral hemisensory changes, neuropathic pain, and spasms. At 6 months after injury, she underwent a spinal accessory to suprascapular nerve, radial nerve triceps branch to axillary nerve, and ulnar fascicle to biceps transfer. At 2-year follow-up, she had improved function with Medical Research Council grade 4 power of shoulder abduction, elbow flexion, and internal and external rotation. Patient 2, a 38-year-old man, sustained a C4-5 fracture-dislocation in a motor vehicle accident and associated right-side hemicord injury involving the C5 and C6 myotomes with relatively preserved distal function. At 9 months after injury, he underwent radial nerve triceps branch to axillary nerve division and ulnar nerve fascicle to musculocutaneous nerve brachialis branch transfer. At 8 months after surgery, electromyography demonstrated evidence of further reinnervation of the deltoid muscle., Conclusions: Our early experience of nerve transfer with 2 patients with combined Brown-Séquard cord injury and brachial amyotrophy indicated acceptable surgical safety and demonstrated encouraging results., (Copyright © 2017 Elsevier Inc.

Purpose: Cervical spontaneous intradural disc herniation (IDH) is an extremely rare condition. We describe a unique case of a patient presenting with a Brown-Séquard syndrome (BSS) and Horner's syndrome (HS). This study aimed to report an unusual case of spontaneous cervical intradural disc herniation that presented with Horner's and Brown-Séquard syndrome (BSS) and discuss difficulties in preoperative diagnosis and treatment difficulties of intradural cervical disc., Methods: Notes and images review, and analysis of the relevant literature., Results: A 45-year old female presented with acute Horner's syndrome and Brown-Séquard syndrome. The magnetic resonance imaging of cervical spine revealed C4-5 disc extrusion with cord compression. The patient underwent urgent decompression through an anterior cervical corpectomy and fusion. Patient fully recovered 6 months after disease onset., Conclusion: We would like to emphasize that prompt and anterior cervical decompression is the treatment of choice, as it directly address the problem and allows dura repair in spontaneous cervical disc herniation.

Brown-Séquard syndrome (BSS) is a rare syndrome and is often described in association with spinal cord injury resulting from hemisection of the spinal cord. BSS due to cervical disc herniation is rare with often delayed diagnosis. The importance of early recognition with imaging cannot be over-emphasized, as the prognosis is better when compared to traumatic and vascular etiologies of BSS. We report a rare case of BBS in an 86-year-old man secondary to cervical disc herniation who had dramatic improvement after surgical intervention. This case highlights the unusual presentation from a very common spinal pathology along with a review of the pertinent literature., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

Background Context: Stab wounds resulting in spinal cord injury of the craniocervical junction are rare. A scissors stab wound to the cervical spinal cord has been reported only once in the literature., Purpose: This paper aimed to report a case of Brown-Séquard-plus syndrome in an 8-year-old boy secondary to a scissors stab wound at the craniocervical junction., Study Design: Case report and review of the literature., Patient Sample: Case report of an 8-year-old boy accidentally stabbed in the neck by scissors, which were thrown as a dart., Methods: The case study of an 8-year-old boy who was hospitalized because of a scissors stab wound at the craniocervical junction. The patient developed Brown-Séquard-plus syndrome on the left side of the body. Magnetic resonance imaging revealed a laceration of the spinal cord at the craniocervical junction with cerebrospinal fluid leakage. Careful cleansing and interrupted sutures of the wounds were performed to prevent cerebrospinal fluid leakage. Rehabilitation therapy was performed 2 days later., Results: A follow-up examination revealed complete recovery of the neurologic deficit 8 months post-injury., Conclusion: Treatment of scissors stab wounds to the cervical spinal cord, whether conservative management or thorough surgical exploration, should be individualized based on history, examination, and imaging. As shown in this case report, despite conservative management, complete recovery, which was unexpected, was attributed to the initial mild laceration of the spinal cord and ipsilateral spinal cord functional compensation., (Copyright © 2016 Elsevier Inc.

Spinal cord injury (SCI) can be complete or incomplete. The level of injury in SCI is defined as the most caudal segment with motor function rated at greater than or equal to 3/5, with pain and temperature preserved. The standard neurological classification of SCI provided by the American Spinal Injury Association (ASIA) assigns grades from ASIA A (complete SCI) through ASIA E (normal sensory/motor), with B, C, and D representing varying degrees of injury between these extremes. The most common causes of SCI include trauma (motor vehicle accidents, sports, violence, falls), degenerative spinal disease, vascular injury (anterior spinal artery syndrome, epidural hematoma), tumor, infection (epidural abscess), and demyelinating processes (). (SDC Figure 1, http://links.lww.com/BRS/B91)(Figure is included in full-text article.).

We report a rare case of thoracic spinal cord herniation due to a defect of the anterior dura mater causing a progressive myelopathy. This case, illustrated by magnetic resonance and surgical imageries, will make the reader aware of this entity and then prevent misdiagnosis.

Case Description: This case reviews the acute care and rehabilitation course of a 44-year-old right-handed woman after an assault with a pocketknife. She suffered multiple stab wounds including penetrating injury to the left side of her neck. Physical examination revealed left hemiplegia (motor score = 57), impaired pinprick sensation on the right caudal to the C5 dermatome, impaired joint position sense on the left, and left ptosis and miosis. Initially she was unable to stand without maximum assistance. MR imaging revealed transection of the left hemicord at the C5 level without cord hemorrhage. CTA of the neck was negative for vascular injury. She completed 18 days of acute inpatient rehabilitation. She used forearm crutches for ambulation at time of discharge. Prior to discharge the patient provided written permission for a case report., Discussion: Stab wounds are the most common cause of traumatic Brown-Séquard syndrome. Horner's syndrome is common in spinal cord lesions occurring in the cervical or thoracic region, however the combination of Horner's and Brown-Séquard syndromes is less commonly reported. In this case report, we review recommendations regarding initial imaging following cervical stab wounds, discuss anatomy and associated neurological findings in Brown-Séquard and Horner's syndromes, and review the expected temporal course of motor recovery., Conclusions: Facilitating motor recovery and optimizing function after Brown-Séquard spinal cord injury are important roles for the rehabilitation team. Imaging is necessary to rule out cord hemorrhage or vascular injury and to clinically correlate cord damage with physical examination findings and expected functional impairments. Documenting associated anisocoria and explaining this finding to the patient is an important element of spinal cord injury education. Commonly, patients with Brown-Séquard injuries demonstrate remarkable motor recovery and regain voluntary motor strength and functional ambulation.

Neurological decompression sickness (DCS) is a rare condition that commonly leads to spinal cord injury. We report the case of a 30-year-old man who developed left-sided weakness and numbness after diving to a maximum depth of 15 m with a total dive time of 205min (10 repetitive dives). To the best of our knowledge, only six cases diagnosed as Brown-Séquard syndrome caused by DCS have been reported in the literature. Divers should be aware of the risk factors of DCS before diving and clinicians should make the diagnosis of spinal cord DCS based primarily on clinical symptoms, not on magnetic resonance imaging findings., (© The Author 2015.

We discuss a rare case of solitary osteochondroma arising from D2-D3 vertebrae presenting as Brown-Séquard syndrome (BSS) in a 28-year-old man following a fall. MRI revealed cord compression by an extradural ventrolateral tumour projecting into the spinal canal at D2-D3 level. Intraoperatively, it was found to be a bony tumour arising from the left of the D2 and D3 vertebral bodies, left pedicles and adjacent articular facets. The neurological deficits of the patient improved after the surgery., (2014 BMJ Publishing Group Ltd.)
