Spontaneous intracranial hypotension: from cerebral venous thrombosis to neurosurgical treatment: a case series experience from a Brazilian tertiary health care center.

Background: Spontaneous intracranial hypotension (SIH) is a secondary cause of headache and an underdiagnosed disease. The clinical presentation can be highly variable. It typically presents with isolated classic orthostatic headache complaints, but patients can develop significant complications such as cerebral venous thrombosis (CVT).

The impact of traumatic herniated discs in cervical facets dislocations treatments: systematic review and meta-analysis.

Background: Traumatic facet dislocations in the subaxial cervical spine, also known as locked facets, are commonly associated with neurological deficits. The fear of the presence of an associated traumatic disc herniation and consequent neurological worsening usually causes a delay in the spinal realignment. This study's aim is an analysis of safety and efficacy when treating acute cervical traumatic facet dislocations using cranial-cervical traction or posterior open reduction and fixation in the presence of disc herniations.

The surgical treatment of subaxial acute cervical spine facet dislocations in adults: a systematic review and meta-analysis.

Adult cervical spine traumatic facet joint dislocations occur when excessive traumatic forces displace the vertebrae's facets, leading to loss of joint congruence. Reduction requires either cranial traction or open surgical procedures. This study aims to appraise the effects of different surgical techniques in the treatment of subaxial cervical spine acute traumatic facet blocks in adults.

Review of best classification systems for diagnosing and treating thoracolumbar spine trauma.

Background: Improved thoracolumbar spine trauma classification (TLSTC) systems can better help diagnose and treat thoracolumbar spine trauma (TLT). Here, we identified the types of injury (rationale and description), instability criteria, and treatment guidelines of TLSTC.

Methods: We used the PubMed/MEDLINE database to assess TLSTC according to the following variables: injury morphology, injury mechanism, spinal instability criteria, neurological status, and treatment guidelines.

Spinal fractures in patients with ankylosing spondylitis: A case report and literature review.

Background: Severe ankylosing spondylitis (AS) affects the entire spine, increasing the risk of vertebral fractures. There are several fusion procedures used (e.g.

Pseudarthrosis in anterior cervical discectomy and fusion with a self-locking, stand-alone cage filled with hydroxyapatite: a retrospective study with clinical and radiological outcomes of 98 levels with a minimum 2-year follow-up.

Objective: The goal of this study was to evaluate the incidence of pseudarthrosis after the treatment of cervical degenerative disc disease (CDDD) with anterior cervical discectomy and fusion (ACDF) in which self-locking, stand-alone intervertebral cages filled with hydroxyapatite were used.

Methods: The authors performed a retrospective cohort study of 49 patients who underwent 1- to 3-level ACDF with self-locking, stand-alone intervertebral cages without plates, with a minimum 2 years of follow-up. The following data were extracted from radiological and clinical charts: age, sex, time and type of pre- and postoperative signs and symptoms, pain status (visual analog scale [VAS]), functional status (Neck Disability Index [NDI]), history of smoking, bone quality (bone densitometry), and complications.

Idiopathic Ventral Spinal Cord Herniation: Video Report and Systematic Review.

Background: Idiopathic ventral spinal cord herniation (ISCH) is a rare disease; however, it is an important differential diagnosis. Its treatment presents some controversies.

Case Description: We report on a 55-year-old woman who had been presenting with relevant back pain and leg weakness for the past 3 years and urinary incontinence for the past 3 months.

Correlation Between Different Interbody Grafts and Pseudarthrosis After Anterior Cervical Discectomy and Fusion Compared with Control Group: Systematic Review.

Background: Cervical spine degenerative disease is one of the main causes of myelopathy. Anterior cervical discectomy and fusion (ACDF) is the most common surgical procedure used to treat cervical myelopathy. Therefore, it is important to study pseudarthrosis rates after ACDF and correlate them with the graft used.

The effect of filum terminale sectioning for Chiari 1 malformation treatment: systematic review.

Purpose: Symptomatic Chiari type I malformation (CM) is treated with posterior fossa decompression with/ without duroplasty. Few authors suggested cerebellar tonsil caudal migration due to a supposed "caudal traction" of cranial nerve structures in a so-called occult tethered cord syndrome. For these authors, filum terminale (FT) sectioning may improve CM symptoms.

Intraoperative Neurophysiological Monitoring in Spine Surgery: A Systematic Review and Meta-Analysis.

Study Design: Systematic literature review and meta-analysis.

Objective: The objective of this systematic literature review was to evaluate if intraoperative neurophysiological monitoring (IONM) can prevent neurological injury during spinal operative surgical procedures.

Summary Of Background Data: IONM seems to have presumable positive effects in identifying neurological deficits.

Mobile cauda equina schwannomas: How to deal with this rare event and avoid surgical complications.

Background: Mobile schwannomas of the cauda equina are rare. Preoperative planning should take into consideration the possibility of tumor migration, avoiding unnecessary additional laminectomy or second operation.

Case Description: A patient with a previously known lumbar schwannoma was being managed conservatively until symptoms exacerbated and led to a new MR.

Spinal thoracic extradural angiolipoma manifesting as acute onset of paraparesis: Case report and review of literature.

Background: Angiolipomas are benign tumors most commonly found in the thoracic spine. They are composed of mature adipocytes and abnormal vascular elements that usually present with a slowly progressive course of neurological deterioration.

Case Description: A 35-year-old female, with a prior history of back pain, acutely developed paraparesis.

Delayed presentation of spinal foreign body - Case report and review of literature.

Background: Although spinal cord injuries are frequent causes of myelopathy in young patients, stab wounds of the spinal cord rarely occur and are typically maximal symptomatic immediately after the trauma.

Case Description: A 31-year-old male developed delayed onset of symptoms 4 years after a stab wound to the cervical spinal cord attributed to a plant needle (plant called Mandacaru). Following removal of the foreign body and decompression/excision of scarring at the C34 level, the patient's symptoms resolved.

Clinical and laboratorial characterization and post-surgical follow-up of 87 patients with non-functioning pituitary macroadenomas.

Objective: It was to assess the main characteristics of patients undergoing pituitary tumor surgery.

Method: Eighty-seven patients (44 men; 44.8±13 years old) were included.

Multifocal intradural extramedullary ependymoma. Case report.

In this paper, the authors present the case of a patient with multifocal intradural extramedullary ependymoma, and they review 18 previously reported cases. A 32-year-old man presented to the authors' institution with a 1-month history of partial medullary syndrome. Magnetic resonance imaging of the neuraxis revealed multifocal intradural extramedullary lesions at the bulbomedullary junction and C2-3, T5-11, L-2, L-4, L-5, and sacrum.

[Size and proliferative index correlation in acoustic neuromas].

Acoustic neuromas are the most common tumors in the cerebellopontine angle. The molecular mechanisms involved in generation and growth of these tumors are not completely elucidated. Many radiological, clinic and immunohistochemistry data were correlated to tumor growth.
