Spinal arachnoid web (AW) is a rare condition causing spinal cord-related issues. Its cause is often idiopathic but can be linked to past trauma or spine surgery. We describe two cases of AWs that developed after subarachnoid hemorrhage (SAH). Case #1 is a 71-year-old male with nonaneurysmal SAH who developed myelopathy 1 year later. Magnetic resonance imaging revealed upper thoracic cord edema and an AW. Case #2 is a 57-year-old female who underwent coiling of a ruptured basilar artery aneurysm and ventriculoperitoneal shunting for hydrocephalus. Twenty months later, she developed mid-thoracic AW requiring surgical resection. Both patients showed symptom improvement postresection avoiding further reoperation. History of SAH is emerging as a risk factor for AW development, emphasizing the importance of monitoring delayed-onset myelopathy and back pain in recent SAH patients.

Patients are often left frustrated after many failed trials of conservative therapies without symptom resolution. Surgery may provide symptom relief for a short period of time, but their pain often returned. Herein, we present three cases of acute arachnoiditis following three different pain procedures: epidural blood patch, IDDS implant, and epidural steroid injection. The patients were diagnosed and treated with corticosteroids within 10 days of the procedure. Two patients were treated with the same oral steroid regiment, while the third patient was treated with both oral and IV steroid. All three patients had good outcomes at the completion of their steroid therapy. This case series may provide insight into treating acute and subacute arachnoiditis from pain interventions.Keywords: arachnoiditis, epidural blood patch, intrathecal pain pump, epidural steroid injection, corticosteroid therapy

- Abstract
A series of 5 patients treated with the fourth ventricle to spinal subarachnoid space stent (FVSSS) is presented. Indication for surgery, surgical technique, pre-operative and post-operative images, and outcome are analyzed. A systematic review of the pertinent literature has also been performed. This is a retrospective cohort review of a series of 5 consecutive patients with refractory syringomyelia who underwent a fourth ventricle to spinal subarachnoid space shunt surgery. The surgical indication was based on the presence of refractory syringomyelia in patients already treated for Chiari malformation or in patients who developed scarring at the level of the outlets of the fourth ventricle following posterior fossa tumor surgery. The mean age at FVSSS was 11.30 ± 5.88 years. Cerebral MRI revealed crowded posterior fossa, with a membrane at the level of the foramen of Magendie. Spinal MRI showed syringomyelia in all patients. Before surgery, the averages of the craniocaudal and the anteroposterior diameter were 22.66 and 1.01 cm, respectively, whereas the volume was 28.16 cm3. The post-operative period was uneventful in 4 out of 5 patients; one child died on the 1st post-operative day due to complications unrelated to surgery. In remaining cases, syrinx marked improvement. The post-operative volume was 1.47 cm3 with an overall reduction of 97.61%. With regard to literature, 7 articles with a total of 43 patients were analyzed. After FVSSS, syringomyelia reduction was observed in 86.04% of cases. Three patients underwent reoperation due to syrinx recurrence. Four patients presented a catheter displacement, one a wound infection and meningitis and one CSF leak requiring placement of a lumbar drain. FVSSS is highly effective in restoring CSF dynamics, with dramatic improvement of syringomyelia. In all our cases, the volume of the syrinx was reduced by at least 90%, with improvement/resolution of accompanying symptomatology. This procedure should be reserved to patients in which other causes of gradient pressure between the fourth ventricle and subarachnoid space are excluded, for example, tetraventricular hydrocephalus. Surgical procedure is not simple, because it requires meticulous microdissection of cerebello-medullary fissure and upper cervical spine, in already operated patients. To avoid migration of the stent, it should be carefully sutured to the dura mater or thick arachnoid membrane. [ABSTRACT FROM AUTHOR]

Secondary spinal arachnoid cysts have rarely been reported but present significant challenges for management. These cysts could be anteriorly located with long rostral–caudal extensions and many are related to arachnoiditis, leading to difficult-to-treat disorders. Thus far, due to the scarcity of reports, the features of the disease and the optimal therapeutic strategies remain unclear. To investigate clinical features and the optimal treatment modalities of secondary spinal arachnoid cysts compared with primary spinal arachnoid cysts. Systematic review. Systematic review identified 103 secondary cases from 80 studies and reports. Condition of symptom relief and duration of treatment response were analyzed. An electronic literature search of the PubMed database was conducted for studies on secondary spinal arachnoid cysts between 1990 and 2022. Non-English publications, nonhuman studies, reports of a primary cyst, studies not including case details, and studies of nonsymptomatic cases were excluded. This systematic review included 103 secondary cases. The most commonly reported etiologies were iatrogenic factors, trauma, and subarachnoid hemorrhage, accounting for 88 intradural extramedullary, 11 extradural, one intradural/extradural, one interdural, and one intramedullary spinal arachnoid cyst after a median duration of 30, 12, and 9 months, respectively. Extradural cysts were more prone to occur at dorsal locations and affect thoracic segments (mean cyst length: 3.4 segments). Intradural cysts showed a relatively higher ventral/dorsal ratio (1:1.09, 1.75:1, and 3.50:1 for cysts occurring from iatrogenic factors, trauma, and subarachnoid hemorrhage, respectively) and thoracic distribution, with a mean cyst length of 4.3 segments (5.1 for ventral and 3.5 for dorsal cysts). For intradural cysts, recurrence risk was lower after surgical resection than after fenestration/marsupialization (12-month recurrence risk: 21.43% vs 50.72%, log-rank test: p=.0248, Gehan–Breslow–Wilcoxon test: p=.0126). In cases treated with shunting, one recurrence (1/8 cases) was noted after external shunting and two recurrences (2/5 cases) after internal shunting at a median follow up of 12 months. Secondary spinal arachnoid cysts, particularly intradural cysts, are rarer and more challenging to treat than primary spinal cysts. Although fenestration/marsupialization is the commonly adopted treatment, the recurrence rate is high. For unresectable cysts, shunting procedures, particularly shunting into a body cavity (eg, pleural or peritoneal cavity) away from the subarachnoid space, could be a therapeutic alternative besides fenestration/marupialization, yet its efficacy requires confirmation by more data.

IntroductionFragile X Tremor and Ataxia Syndrome is a progressive neurodegenerative disorder that develops in some FMR1 premutation carriers. The objective of this study is to characterize how cytokine levels are altered in the FXTAS brain.MethodsFresh frozen cerebellar tissue from FXTAS cases and controls was homogenized and analyzed for 12 different cytokines using a commercially available ELISA panel.ResultsRelative to controls, FXTAS cases showed large and significant increases in the cytokines IL-12 and TNFα. There were large but non-significant increases in the levels of IL-2, IL-8, and IL-10 in FXTAS cases. The cytokines IL-1A, IL-1B, IL-4 IL-6, IL-17A, IFNγ, and GM-CSF were not different between FXTAS and control subjects.ConclusionsFor the first time, we demonstrate an increase in the pro-inflammatory cytokines TNFα and IL-12 in the FXTAS brain, both of which are implicated in the pathogenesis of Multiple Sclerosis, another neurodegenerative disorder that predominantly consists of white matter disease.

Tuberculosis involving the spinal cord is associated with high mortality and disabling long-term sequelae. Although tuberculous radiculomyelitis is the most frequent complication, pleomorphic clinical manifestations exist. Diagnosis can be challenging among patients with isolated spinal cord tuberculosis due to diverse clinical and radiological presentations. The principles of management of tuberculosis of the spinal cord are primarily derived from, and dependent upon, trials on tuberculous meningitis (TBM). Although facilitating mycobacterial killing and controlling host inflammatory response within the nervous system remain the primary objectives, several unique features require attention. The paradoxical worsening is more frequent, often with devastating outcomes. The role of anti-inflammatory agents such as steroids in adhesive tuberculous radiculomyelitis remains unclear. Surgical interventions may benefit a small proportion of patients with spinal cord tuberculosis. Currently, the evidence base in the management of spinal cord tuberculosis is limited to uncontrolled small-scale data. Despite the gargantuan burden of tuberculosis, particularly in lower and middle-income countries, large-scale cohesive data are surprisingly sparse. In this review, we highlight the varied clinical and radiological presentations, performance of various diagnostic modalities, summarize data on the efficacy of treatment options, and propose a way forward to improve outcomes in these patients.

Chiari I malformation has been defined as cerebellar tonsillar descent greater than 5 mm below the foramen magnum. Suboccipital decompression remains the mainstay of treatment for symptomatic patients. Other conditions sometimes have imaging features that mimic Chiari I malformation. These patients are at risk of misdiagnosis and mismanagement, including surgery that may be unnecessary or may even worsen the underlying condition. The aim of this study was to analyse a series of Chiari I malformation mimics and identify differentiating imaging features. The mimics are categorised as post-traumatic cranio-cervical junction arachnoiditis, dural band, spontaneous intracranial hypotension, idiopathic intracranial hypertension, and cysts. Better understanding of these conditions will assist with diagnosis and optimal management, including avoiding unnecessary surgery. [ABSTRACT FROM AUTHOR]

Abstract Background Tubercular infection of the brain and spine is relatively common in endemic regions of the world. Central nervous system tuberculosis can have varied manifestations. The familiar imaging findings are hydrocephalus, ring-enhancing tuberculomas, and meningeal enhancement, having a preference for basal regions. Myelitis is the most common imaging manifestation of spine, with holocord involvement being a rare presentation, as seen in our case. Case presentation We present a case of a pediatric patient undergoing treatment for a tubercular infection of the brain. The patient developed acute onset quadriparesis, manifesting as holocord transverse myelitis on imaging. The imaging findings in the brain manifested as basal meningeal enhancement and non-communicating hydrocephalus, managed by shunt placement. As of the latest, the patient is on follow-up and has a stable disease course. Clinical and laboratory investigations excluded other infectious and non-infectious causes of transverse myelitis, including neuromyelitis optica spectrum disorders. Conclusions Longitudinally extensive transverse myelitis is a rare complication of tubercular myelitis seen as a long-segment signal abnormality with swelling of the cord and corresponding post-contrast enhancement. Involvement of the entire cord is rare, with a handful of cases reported in the literature.

MESOTHELIUM , *SUBARACHNOID space , *CENTRAL nervous system , *ARACHNOIDITIS , *MENINGES - Abstract
The central nervous system is lined by meninges, classically known as dura, arachnoid, and pia mater. We show the existence of a fourth meningeal layer that compartmentalizes the subarachnoid space in the mouse and human brain, designated the subarachnoid lymphatic-like membrane (SLYM). SLYM is morpho- and immunophenotypically similar to the mesothelial membrane lining of peripheral organs and body cavities, and it encases blood vessels and harbors immune cells. Functionally, the close apposition of SLYM with the endothelial lining of the meningeal venous sinus permits direct exchange of small solutes between cerebrospinal fluid and venous blood, thus representing the mouse equivalent of the arachnoid granulations. The functional characterization of SLYM provides fundamental insights into brain immune barriers and fluid transport. [ABSTRACT FROM AUTHOR]

ABSTRACT Introduction: Arachnoiditis ossificans (AO) in the spine is a rare entity characterized by progressive calcification of the arachnoid and dural sac, with consequent neurological involvement. Objective: Review the causes, clinical manifestations, and complementary studies for their correct diagnosis. Method: Systematic review under PRISMA guidelines, with search in Pubmed, Lilacs, and Embase. Patient demographics (sex and age), history reported as a cause of AO and time elapsed between cause and diagnosis of AO, clinical manifestations, and complementary studies used for diagnosis were collected. Results: 38 articles, of which we collected 46 patients (25 women, 21 men), mean age of 52 years. The most frequent cause was previous spine surgery and myelography with fat-soluble contrast. The most frequent symptoms were insufficient muscle strength (74%) and pain (69%). CT was used in 76%. The most frequent location was thoracic (35%). Conclusion: Its pathogenesis is unclear; described as the final cause of a chronic inflammatory process in the arachnoid with the consequent bone metaplasia. Diagnosis usually precedes a long period of pain and progressive neurological symptoms. The most sensitive and specific complementary study for the diagnosis is the tomography without contrast, which should be requested in case of clinical suspicion. Level of Evidence II; Systematic Review.

Arachnoiditis is a rare clinical entity that usually presents with severe debilitating radiating pain that can pose a challenge in diagnosis especially in areas without appropriate imaging modalities. We present a 26-year-old male with progressive lower back pain with radiation to the lower extremities, aggravated by movement and touch. We diagnosed idiopathic arachnoiditis based on cerebrospinal fluid analysis and magnetic resonance imaging. He was managed with a 5-day course of methylprednisolone and analgesics with a good outcome. Severe back pain without a specific cause in a young patient should be investigated with proper imaging modalities and lumbar puncture if warranted to evaluate the cause.

- Abstract
Objectives: The aim of this study was to determine the occurrence of dural puncture, indicated by cerebrospinal fluid (CSF) outflow, in cats receiving neuraxial anesthesia through a lumbosacral injection guided by a pop sensation method. Methods: This was an observational, retrospective study. Cats that were scheduled for lumbosacral neuraxial anesthesia were included. Medical records were analyzed to investigate: (1) demographic data; (2) neuraxial anesthesia performed (epidural/spinal); (3) type of needle used, including gauge and length; (4) presence of CSF (yes/no) and/or blood (yes/no) in the hub of the needle; and (5) flicking of the tail during needle advancement (yes/no). Results: A total of 94 medical records were analyzed. A 22 G 50 mm Tuohy needle was used in all cats scheduled for an epidural injection (n = 60), whereas a 22 G 40 mm Quincke needle was used in all cats scheduled for an intrathecal injection (n = 34). CSF outflow was detected in 55/60 (91.7%) cats in which a Tuohy needle was used, and 34/34 (100%) of the cats in which a Quincke needle was used (P = 0.15). Flicking of the tail was detected in 41/60 (68.3%) and in 24/34 (70.6%) injections with Tuohy and Quincke needles, respectively (P >0.99). Traces of blood, but not active blood outflow, were detected via staining of the first drops of CSF in 2/34 cats in which Quincke needles were used and in none of the cats in which Tuohy needles were used (P = 0.12). Conclusions and relevance: This study shows that the lumbosacral approach for neuraxial anesthesia in cats may result in a dural sac puncture when 22 G Quincke or Tuohy needles are used. The pop sensation method should be deemed effective in predicting intrathecal but not epidural needle placement. [ABSTRACT FROM AUTHOR]

Background: Arachnoiditis refers to chronic inflammation of the arachnoid mater and subarachnoid space due to three major etiologies: chemical, mechanical, and postinfectious. As a rare disease with variable symptomatology and severity at presentation, arachnoiditis can be extremely debilitating with many complications, prominent among which is syringomyelia. Methods: We reviewed current literature concerning postinfectious spinal arachnoiditis and associated syringomyelia with emphasis on the treatment options that have been used to date and discuss their respective benefits and drawbacks. Results: It is critical to understand the natural history and potential complications of patient with postinfectious arachnoiditis. Surgical and medical treatments both have their own merits and demerits. Different surgical approaches have been employed with variable success rates. Conclusion: At present, no consensus exists regarding management of these patients due to the variable nature of the disease that affects treatment efficacy; however, surgical intervention in selected cases may be beneficial.

- Abstract
Background Trigeminal neuralgia (TN) is a craniofacial pain characterized by sudden onset, brief, severe, recurrent shooting pain within one or more branches of the trigeminal nerve (CN V). Based on its clinical presentation, TN may be classified as purely paroxysmal or paroxysmal with concomitant continuous pain (CCP), previously known as typical and atypical, respectively. Microvascular decompression (MVD) surgery for releasing the CN V from a neurovascular conflict is an effective and safe treatment for TN. During MVD of patients manifesting TN with CCP, the involvement of an abnormal arachnoid tissue is a common finding. The etiology and pathophysiology behind the appearance of this tissue are unknown; however, it is more commonly found in this variant of the disease. Methods From January 2015 to December 2016, a total of 330 patients diagnosed with TN were evaluated at our clinic. Among them, 31 individuals (9.4%) presented with paroxysmal TN with CCP, with 16 patients (51.6%) undergoing MVD. During surgery, samples of altered arachnoid tissue were collected from five patients and subjected to Hematoxylin-Eosin staining and immunohistochemistry for S100 and CD2 Results In a long-term follow-up, 80% of patients operated by DMV remains pain free. Analysis of biopsies revealed chronic fibrosis (n=4), hyperplasia of neurothelial cells (n=3), dystrophic calcifications (n=1). Immunohistochemistry was positive for S100 (n=3) and CD20 (n=3) inflammatory markers. Conclusion Chronic inflammation in the arachnoid tissue involved in paroxysmal TN with CCP could be a contributor to the pathophysiology of this variant of the disease., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Segura-Lozano et al.)

Background: Coccidioidomycosis meningitis (CM) is the most aggressive form of coccidioidomycosis, requiring lifelong antifungal treatment and often cerebrospinal fluid (CSF) diversion. Long-standing CM can be associated with spinal complications such as arachnoiditis. However, studies describing the frequency, clinical, and imaging characteristics of arachnoiditis in patients with CM are limited. Methods: We identified 133 patients with CM based on CSF culture, PCR, or serology between January 2010 and December 2020. Of these, 37 patients underwent spinal imaging. Data on demographics, risk factors, symptoms, antifungal therapy, surgical management, follow-up visits, adherence, serological trends, and imaging findings were reviewed. Results: Abnormal findings were observed in 30 of the 37 patients with CM who underwent spinal imaging. The imaging abnormalities noted in our study included leptomeningeal enhancement (53%), arachnoiditis (53%), syringomyelia (23%), cord signal abnormalities (10%), and osteomyelitis (7%). Of the 30 patients, 90% had symptoms, such as weakness, numbness, or urinary retention. The incidence of arachnoiditis in the present study was 12%. Higher initial CSF protein levels and intra cranial pressure were associated with a higher risk of developing arachnoiditis/syringomyelia. Management of CM was challenging, as evidenced by shunt failure (46%), medication non-compliance (57%), and lack of adequate follow-up (60%). Persistent disabilities were noted in 62% of the patients. Conclusions: Patients with CM develop spinal complications such as arachnoiditis, or syringomyelia. Many cases may go undetected due to lack of symptoms in early stages. CM management challenges such as shunt failure, lack of follow-up care, and medication noncompliance, were frequent.

- Abstract
Background: Adhesive arachnoiditis is a rare yet serious complication that may occur following subarachnoid hemorrhage (SAH). In this circumstance, it is mainly due to ruptured vertebral artery (VA) or posterior inferior artery (PICA) aneurysms. It disrupts cerebrospinal fluid (CSF) flow leading to complications such as spinal arachnoiditis, syringomyelia, trapped 4th ventricle, or a combination of these conditions. Evidence for effective treatment strategies is currently limited. We aimed to review the epidemiology, clinical characteristics, treatment, complications, outcomes, and prognosis of cranio-vertebral junction and spinal adhesive arachnoiditis resulting from ruptured VA and PICA aneurysms., Methods: This study involved a comprehensive literature review and complemented by our own case. We focused on adult cases of arachnoiditis, syringomyelia, and trapped 4th ventricle with SAH caused by ruptured VA or PICA aneurysms, excluding cases unrelated to these aneurysms and those with insufficient data., Results: The study included 22 patients, with a mean age of 52.4 years. Symptoms commonly manifest within the first year after SAH and timely diagnosis requires a high index of suspicion. Treatment approaches included lysis of adhesions and various shunt procedures. Most patients showed improvement post-treatment, though symptom recurrence is significant., Conclusion: Adhesive arachnoiditis is a critical complication following SAH, most commonly from ruptured VA and PICA aneurysms. Early detection and individualized treatment based on the type of arachnoiditis and CSF flow impact are crucial for effective management. This study underscores the need for tailored treatment strategies and further research in this field., (Copyright © 2024. Published by Elsevier Masson SAS.)

Background: Prior imaging studies characterizing lumbar arachnoiditis have been based on small sample numbers and have reported inconsistent results. Purpose: To review the different imaging patterns of lumbosacral arachnoiditis, their significance, and clinical implications. Study type: Retrospective. Population: A total of 96 patients (43 women; average age 61.3 years) with imaging findings of arachnoiditis (postsurgical: N = 49; degenerative: N = 29; vertebral fracture: N = 6; epidural and subdural hemorrhage: N = 3, infectious: N= 1; other: N = 8) from January 2009 to April 2018. Field strength/Sequence: Sagittal and axial T2‐weighted Turbo Spin Echo at 1.5 T and 3 T. Assessment: Chart review was performed to assess the cause of arachnoiditis, and imaging was reviewed by two musculoskeletal and three neurology radiologists, blinded to the clinical data and to each other's imaging interpretation. Previous classification included a three‐group system based on the appearance of the nerve roots on T2‐weighted images. A fourth group was added in our review as "nonspecified" and was proposed for indeterminate imaging findings that did not fall into the classical groups. The presence/absence of synechiae/fibrous bands that distort the nerve roots and of spinal canal stenosis was also assessed. Statistical tests: The kappa score was used to assess agreement between readers for both classification type and presence/absence of synechiae. Results: Postsurgical (51%) and degenerative changes (30%) were the most common etiologies. About 7%–55% of arachnoiditis were classified as group 4. There was very poor classification agreement between readers (kappa score 0.051). There was also poor interreader agreement for determining the presence of synechiae (kappa 0.18) with, however, strong interreader agreement for the presence of synechia obtained between the most experienced readers (kappa 0.89). Data Conclusion: This study demonstrated the lack of consensus and clarity in the classification system of lumbar arachnoiditis. The presence of synechia has high interreader agreement only among most experienced readers and promises to be a useful tool in assessing arachnoiditis.

Background: Spinal arachnoiditis is an insidious disease caused by an inflammatory process of the arachnoid membrane resulting from many possible causes. Several factors such as spinal surgery, myelography, or infectious meningitis are known to cause adhesive arachnoiditis. Multiple studies proposed that the initial stage of syringomyelia in spinal arachnoiditis would be intramedullary cystic degeneration caused by ischemia due to circulatory disturbance in the pia-arachnoid. Disturbance of cerebrospinal fluid flow around the spinal cord has an important role in the development of syringomyelia due to spinal arachnoiditis. The presentation of spinal arachnoiditis depends on the level of the disease. For instance, Lumbar or lumbosacral adhesive arachnoiditis is usually related to lumbar disc diseases, and radicular pain due to involvement of the cauda equina is the main symptom. Our case represents a rare cause of arachnoiditis for a patient was presented with lower limb weakness and found to have extensive syringomyelia. Case description: 29-year-old male patient, presented with 3 days history of progressive lower limbs weakness. He had 3 months history of mild lower back pain and subjective left lower limb weakness. MRI showed extensive intramedullary hyperintense lesion extending from T3 to L1 with scattered post-contrast nodular enhancement. Diagnosis of arachnoiditis with syringomyelia done. The patient underwent Thoracic 8 laminectomy, arachnoid biopsy, and syrinx to subarachnoid space shunt. Tissue culture-confirmed Staphylococcus cohnii. Conclusion: Arachnoiditis is a common pathology with multiple causes. However, isolated bacterial arachnoiditis is rare and has not been mentioned in literature before to our knowledge. We present a case of arachnoiditis proven to be bacterial by tissue culture from the thickened arachnoid layer we took during the surgery after we exclude all other causes.

A report from Lausanne University Hospital discusses research findings on subarachnoid hemorrhage. The authors describe a case of intradural extramedullary cavernoma with an initial presentation of subarachnoid hemorrhage, leading to spinal arachnoiditis. The management of subarachnoid hemorrhage is challenging, and there is currently no clear strategy for its treatment. The authors suggest that lumbar drainage could aid in managing subarachnoid hemorrhage and preventing the development of spinal arachnoiditis. They also propose mini-invasive intrathecal endoscopic adhesiolysis as a reasonable approach to reduce the risk of aggravating spinal arachnoiditis. [Extracted from the article]

Arachnoiditis is a rare clinical entity that usually presents with severe debilitating radiating pain that can pose a challenge in diagnosis especially in areas without appropriate imaging modalities. We present a 26-year-old male with progressive lower back pain with radiation to the lower extremities, aggravated by movement and touch. We diagnosed idiopathic arachnoiditis based on cerebrospinal fluid analysis and magnetic resonance imaging. He was managed with a 5-day course of methylprednisolone and analgesics with a good outcome. Severe back pain without a specific cause in a young patient should be investigated with proper imaging modalities and lumbar puncture if warranted to evaluate the cause. [ABSTRACT FROM AUTHOR]

- Abstract
• Syringomyelia is a rare but serious complication of tuberculous meningitis. • TB syringomyelia is often refractory to both surgical and medical management. • Surgery does not have significantly better outcomes than medical management. Determinants of tuberculosis (TB) syringomyelia, its management options and outcomes are still under investigation. The aim of this study is to present a case of TB syringomyelia with markedly improved symptoms status-post surgery and to understand the clinical characteristics and outcomes of 33 TB syringomyelia cases reported in the literature. Specifically, we examined the differences between patients who were managed medically and those who underwent surgical intervention. Inclusion criteria for the cases were (1) syringomyelia caused by TB infection rather than co-occurrence of these conditions, (2) management protocol described, and (3) post-treatment outcome described. The median age was 30 years (interquartile range (IQR): 23–40) with 55% males. The median time between TB onset to syringomyelia diagnosis was 2 years. Nineteen patients were surgically treated, 11 were medically treated, and 3 received no treatment. Twenty-one patients showed improvement in at least one prior symptom, but no patient experienced a full recovery. Those that underwent surgical intervention were more likely to have TB meningitis (95% vs. 64%, p < 0.05) upon initial TB presentation and have a greater interval between TB onset and syringomyelia presentation (median of 2.6 vs. 0.33 years, ns). A greater proportion of the surgically managed patients experienced improvement in any symptom (74% vs. 45%, ns). Future case-controlled studies with larger sample sizes are required to validate and further understand the outcomes of surgically-managed TB syringomyelia. [ABSTRACT FROM AUTHOR]

Abstract Background Autologous epidural blood patch (AEBP) is effective for post-dural-puncture headache (PDPH). In some cases, repeat procedures are required for complete cure. In rare instances, severe adverse effects can occur. We present a case of neurologically complicated AEBPs, one of which was performed at the interspace of unintentional dural puncture (UDP). Case presentation A 40-year-old primigravida sustained UDP at the L2–3 interspace during combined spinal-epidural anesthesia for a scheduled cesarean section. She developed PDPH and underwent a single AEBP at L3–4. The PDPH recurred and she required another AEBP at L2–3, after which she reported radicular pains. A diagnosis of subdural hematoma and adhesive arachnoiditis was made. Her symptoms partially resolved in the following months. Conclusion It may be prudent to reconsider the use of repeated AEBP and to avoid the interspace of UDP. A thorough evaluation is warranted to exclude treatable lesions when adverse effects occur.

Rappaport Faculty of Medicine, Technion – Israel Institute of Technology, Haifa, Israel; 3Amitim Clinic, Haifa, Israel; 4Department of Medical Imaging, Carmel Medical Center, Haifa, Israel; 5Department of Medical Imaging, Rambam Health Care Campus, Haifa, Israel Abstract: Lumbar epidural steroid injections (LESIs) are commonly used for managing lower back pain (LBP) and radicular pain. LESIs are generally considered safe with only rare serious complication. One very rare complication that is frequently cited in the literature is adhesive arachnoiditis. However, a literature search failed to detect even one published manuscript, clearly documenting LESI induced arachnoiditis. This article presents two patients who received a transforaminal L5–S1 and two L3–L4 interlaminar LESIs. Although the presented patients developed clear radiological (MRI) findings of arachnoiditis, they were not accompanied by any improvement or deterioration in their clinical condition. The article also reviews the literature on the prevalence, pathogenesis, diagnosis, and clinical features of adhesive arachnoiditis. Literature suggests that adhesive arachnoiditis following LESIs is a rare entity, which – as seen in our patients – has clear radiological characteristics but uncertain pathogenesis. It has a large spectrum of clinical presentation, ranging from an incidental finding to a serious neurological sequela. In at least some patients with adhesive arachnoiditis following LESI, the radiological and clinical findings may fail to correlate with each other. In light of the fact that LESI is one of the most commonly performed procedures for managing LBP, clinicians should be aware of this rare yet existing entity.

This article aims to familiarize the reader with the MR imaging findings of tubercular radiculomyelitis (TBRM) and to identify the sources of infection. We evaluated 29 patients on a 1.5 T GE MRI in a cross-sectional study. MRI of the spine with contrast and lumbar puncture were performed in all patients. MRI brain was performed for 13 patients. The typical and atypical manifestations enlisted in this article, will enable early detection of TBRM when the clinical history is ambiguous, as TBRM can present with low backache in both retrovirus positive and negative patients.

Neurocysticercosis (NCC) is the commonest parasitic infection of the central nervous system. There is significant difference in incidence of NCC depending on geographic location, and incidence as high as 4% is reported in the endemic areas. It results from human affliction by the larval stage of Taenia solium. Spinal NCC is quite rare as compared with cranial NCC and accounts for 1.5%–3% of all cases. Both spine and cranium can be rarely involved in NCC, and cranial involvement usually precedes the spinal involvement. We report a case of a 51-year-old woman who had spinal involvement first in the form of spinal intradural extramedullary disease and then developed cranial involvement more than 1 year later. She developed spinal arachnoiditis. She developed communicating hydrocephalous requiring ventriculoperitoneal shunt. Later she developed isolated fourth ventricle and required excision of the fourth ventricular NCC. The unique aspects of our patient were a very aggressive course and involvement of cranium after spinal involvement. We describe her clinical course over 3 years and the management done. NCC can sometimes follow a very aggressive course and can involve both cranial and spinal compartments. Management of such patients is not standardized given the rarity of such cases.

Objective: To report a case of arachnoiditis as a complication of epidural blood patch procedures and to systematically review the diagnostic workup, clinical outcomes, and treatment modalities reported in the literature. Background: Epidural blood patching is an effective treatment for low‐pressure headache secondary to spontaneous cerebrospinal fluid leak or iatrogenic post‐dural puncture. Spontaneous intracranial hypotension is believed to be a rare headache disorder, but recently has been diagnosed at higher frequencies, making it an important differential diagnosis for intractable headaches. Arachnoiditis has surfaced as a rare complication of epidural blood patching. Symptom presentation does not always correlate with evidence of meningeal enhancement on imaging. Optimal methods for treatment remain largely unknown. Methods: Databases Embase and PubMed were searched for all published studies on arachnoiditis post‐epidural blood patch using a combination of the following medical subject headings and keywords: arachnoiditis, arachnoid inflammation, adverse event, and epidural blood patch. All original English‐language articles that described arachnoid and/or meningeal inflammation in conjunction with epidural blood patch procedures were included for analysis. Title and abstract screening, data extraction, and risk of bias assessment were conducted independently and in duplicate by two reviewers. Results: Seven other cases of arachnoiditis post‐blood patch placement have been documented, most of which were diagnosed via magnetic resonance imaging. Six of these were a result of a spinal‐epidural anesthesia for labor and delivery. Common symptoms reported were headache, back and radicular pain, paresthesia, and motor weakness. There are currently no proven consensus‐based treatment recommendations available. While intravenous methylprednisolone followed by oral prednisone taper was found to be effective in the case presented, the benefit of other multi‐modal therapies was unclear. Conclusions: Headache specialists who treat postural headache should be aware of arachnoiditis as a potentially severe complication of epidural blood patch. The case presented is the first of its kind to report arachnoiditis as a complication of high‐volume blood patch for the treatment of spontaneous intracranial hypotension. More studies are required to determine suitable treatment options for post‐epidural blood patch arachnoiditis. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Spinal arachnoiditis can result from various factors, including spinal subarachnoid hemorrhage (sSAH). In this paper, the authors describe a case of intradural extramedullary cavernoma with an initial presentation of subarachnoid hemorrhage leading to multilevel spinal arachnoiditis to discuss the pathophysiology and optimal treatment strategy., Observations: Spinal intradural extramedullary cavernoma manifesting with sSAH is a rare clinical presentation; therefore, there is no clear strategy for the management of sSAH. Spinal arachnoiditis is a result of chronic inflammation of the pia arachnoid layer due to hematomyelia. No effective treatment that interrupts this inflammatory cascade and would also prevent the development of spinal arachnoiditis has been described to date., Lessons: Lumbar drainage could aid in sSAH management, relieve spinal cord compression, and restore the normal spinal cerebrospinal fluid circulation gradient. It could help to clear the blood degradation products rapidly and prevent early inflammatory arachnoiditis development. Mini-invasive intrathecal endoscopic adhesiolysis appears to be a reasonable approach for reducing the risk of aggravating spinal arachnoiditis with a mechanical-surgical stimulus. Whether a conservative approach should be applied in these patients with mild myelopathy symptoms is still debatable.
