Spinal arachnoiditis (SA) is an extremely rare and delayed complication of subarachnoid hemorrhage (SAH). Little is known about its underlying pathogenesis and subsequent clinical course. A middle-aged patient presented with the worst headache of her life and a grade 3 SAH of the basal-cisterns and posterior fossa was identified on Computed Tomography scans (CT). Angiography revealed a ruptured dissecting aneurysm of the left vertebral artery (VA-V4), as well as an unruptured left Anterior Cerebral Artery (ACA-A1) aneurysm...

Arachnoid cysts are an uncommon postoperative complication and can result in back pain, radiculopathy, and/or cauda equina syndrome. For symptomatic postoperative arachnoid cysts, surgical management is the accepted treatment. While excision of arachnoid cysts is the preferred surgical method, cysts with adhesions to nerve roots and/or dura can be treated with cyst fenestration to reduce morbidity of excision. Surgeons should be prepared for dural defects after cyst excision, which can require dural grafting and lumbar drains for cerebrospinal fluid diversion...

OBJECTIVE: A pseudomeningocele and an incisional cerebrospinal fluid leak are considered frequent complications following neurosurgical operations. The rate of these complications especially increases following neurosurgical procedures on the posterior cranial fossae. According to some publications, the rate of pseudomeningoceles has been reported as high as 40%, whereas that of incisional cerebrospinal fluid leaks is up to 17%. For the purposes of reducing the risk of these complications after a midline suboccipital craniotomy, we propose suturing the arachnoid membrane of the cisterna magna...

OBJECTIVE:  Abnormalities within the spinal arachnoid space are often treated surgically, but they can be challenging to detect with conventional magnetic resonance imaging (MRI) sequences. 3D-CISS sequences are considered superior in evaluating structures surrounded by cerebrospinal fluid (CSF) due to the high signal-to-noise ratio, high contrast-to-noise ratio and intrinsic insensitivity to motion with minimal signal loss due to CSF pulsations. Our objective was to describe findings and advantages in adding 3D-CISS sequences to routine MRI in patients affected by spinal arachnoid diverticula (SAD) or arachnoid adhesions...

BACKGROUND: The rupture of an isolated spinal aneurysm is an exceptional occurrence. It might be responsible for a spinal subarachnoid haemorrhage (SSAH) that in rare cases can be complicated by arachnoiditis. Among the former the adhesive type is the most severe leading to the formation of a cyst and/or a syrinx. PATIENTS AND METHODS: The literature review was performed via a PubMed search using the following keywords. Adhesive arachnoiditis; spinal subarachnoid haemorrhage; spinal arachnoiditis; spinal arachnoid cyst; arachnoid cyst ...

BACKGROUND: Adult tethered cord syndrome is a rare neurologic disorder that classically presents with back or leg pain, weakness, and urinary dysfunction. Spinal cord tethering has been associated with acquired Chiari malformations. Whereas the effects of tethered cord release on Chiari malformation symptoms have been described previously, we report an unusual case of acquired tethered cord syndrome following Chiari decompression. CASE DESCRIPTION: We report a 68-year-old man with a history of distant T12-level spinal cord injury and 2 weeks of progressive bilateral lower extremity weakness...

Autosomal recessive disorders such as Fukuyama congenital muscular dystrophy, Walker-Warburg syndrome, and the muscle-eye-brain disease are characterized by defects in the development of patient's brain, eyes, and skeletal muscles. These syndromes are accompanied by brain malformations like type II lissencephaly in the cerebral cortex with characteristic overmigrations of neurons through the breaches of the pial basement membrane. The signaling pathways activated by laminin receptors, dystroglycan and integrins, control the integrity of the basement membrane, and their malfunctioning may underlie the pathologies found in the rise of defects reminiscent of these syndromes...

Spinal cord injury arising during anaesthetic practice is a rare event, but one that carries a significant burden in terms of morbidity and mortality. In this article, we will review the pathophysiology of spinal cord injury. We will then discuss injuries relating to patient position, spinal cord hypoperfusion and neuraxial techniques. The most serious causes of spinal cord injury - vertebral canal haematoma, spinal epidural abscess, meningitis and adhesive arachnoiditis - will be discussed in turn. For each condition, we draw attention to practical, evidence-based measures clinicians can undertake to reduce their incidence, or mitigate their severity...

OBJECTIVE The pathophysiology underlying tonsillar herniation and CSF obstruction in Chiari malformation Type I (CM-I) is unclear, and the cause of CM-I-associated syringomyelia is not well understood. A better understanding of this pathophysiology is important for an improved treatment strategy. Therefore, the authors sought to identify, characterize, and examine the intradural pathology and CSF flow pathophysiology in the posterior fossa and at the level of the foramen magnum that occurs in the setting of CM-I...

OBJECTIVE: Though it is usually successful, failure or delayed pain recurrence may occur after gamma knife surgery (GKS) in patients with trigeminal neuralgia (TN), and additional intervention may be required. This study aimed to investigate whether the safety and efficacy of microvascular decompression (MVD) were influenced by prior GKS. PATIENTS AND METHODS: The authors retrospectively evaluated 36 consecutive TN patients who underwent MVD after failed GKS from January 2012 to June 2013...

Hemifacial spasm is a hyperactive cranial nerve disease mainly characterized by unilateral facial muscles paroxysmal, involuntary, irregular and clonic convulsion. Standard microvascular decompression is currently the most effective solution. During operation, it is pivotal to conduct a sharp dissection of arachnoid membrane around the caudal cranial nerves and facial, auditory nerves for fully exposure of pontomedullary sulcus, and lateral pontine region. In this article, the authors demonstrate a hemifacial spasm patient who underwent microvascular decompression successfully in their department...

We reported the recovery of sensorineural hearing loss and tinnitus in a 22-year-old man after complete removal of intracranial portion of jugular foramen schwannoma via the retrosigmoid approach. The aim of this case report was to present the excision of a large jugular foramen schwannoma via the retrosigmoid approach and to describe the improvement of sensorineural hearing loss related to arachnoid inflammations due to chronic arachnoiditis after suboccipital craniectomy. The recovery of sensorineural hearing loss and tinnitus after release of arachnoid adhesions may indicate the clinical significance of these adhesions or arachnoiditis, which should also be considered and investigated in the etiology of other neurotological diseases...

Electrospun fibrous membranes provide suitable physical anti-adhesion barriers for reducing tissue anti-adhesion following surgery. However, often during the biodegradation process, these barriers trigger inflammation and cause a foreign body reaction with subsequent decrease in anti-adhesion efficacy. Here, a facile strategy comprising the incorporation of ibuprofen (IBU) into implantable membranes and its sustained release was proposed in order to improve anti-adhesion effects and neurological outcomes, namely to prevent failed back surgery syndrome (FBSS)...

BACKGROUND: Dissection of brain surface adhesions during recurrent glioma surgery carries a risk of injury to cortical vessels and important surface vessels. We present our experience with the use of BioD film, a biocompatible amniotic membrane implant, to help prevent postoperative adhesions. We describe a novel method for preventing postoperative adhesions after high-grade glioma surgery using BioD film. METHODS: Amniotic sac implants were laid on the brain surface after resection of gliomas located near major surface arteries (sylvian fissure) and major veins (parasagittal convexity)...

A "dorsal spinal arachnoid web" is the thickened arachnoid band on the surface of the spinal cord which disturbs the cerebrospinal fluid (CSF) flow, known as a rare cause of thoracic myelopathy. The ideal treatment is controversial because of the risk of readhesion after simple resection of the web. A subarachnoid-subarachnoid bypass is a method to reestablish CSF flow through a silicon tube between the cranial and caudal subarachnoid space. This method is reported to be useful for traumatic syringomyelia, adhesive arachnoiditis, etc...

The prevalence of syringomyelia (SM) caused by adhesive arachnoiditis (AA) is 2 to 4 cases per 100000 population. Surgical treatment of this pathology usually includes implantation of shunts into the cyst cavity or opening and drainage of the cavity. In this case, SM continues to progress in 72-100% of patients. Unsatisfactory outcomes of this surgical approach necessitate searching for other treatment options. PURPOSE: To define the optimal amount of surgery for SM associated with AA and the criteria for assessment of surgery outcomes...
