Posttubercular adhesive arachnoiditis is a rare, late complication of tubercular meningitis. Syringomyelia can develop as a consequence of intramedullary cystic lesions and cerebrospinal fluid (CSF) flow disturbance around the spinal cord, even after successful chemotherapy. We reviewed the literature related to posttubercular syringomyelia treatment and suggest a new combined surgical approach. A 25-year-old Nigerian male patient presented with legs numbness, urinary disturbance, and legs weakness. Spinal magnetic resonance revealed a T5-T7 syringomyelia, secondary to adhesive spinal arachnoiditis related to a history of tuberculous meningitis...

BACKGROUND CONTEXT: A paucity of data exists studying outcomes of patients with syringomyelia undergoing spinal deformity correction. The literature does not stratify patients by syrinx size, which is likely a major contributor to outcomes. PURPOSE: To compare differences in outcomes between patients with large (≥ 4mm) and small syrinxes (< 4mm) undergoing spinal deformity correction. DESIGN: Retrospective review PATIENT SAMPLE: 28 patients (11 with large syrinx [LS, ≥ 4mm] and 17 with small syrinx [SS, < 4mm])...

Syringomyelia (SM) develops due to the disturbance of cerebrospinal fluid dynamics, spinal fixation or a spinal tumor. The disturbance of cerebrospinal fluid dynamics in the area of the foramen magnum leads to the progression of SM in Chiari 1 malformation (CM1). CM1 is the most prevalent pathology of craniovertebral junction associated with SM. The prevalence of CM1 varies from 3 to 8 per 100 000 population but SM is diagnosed in 65% of patients with CM1. Clinical symptoms of CM1 and SM include pain in the occipital area, gait disturbances due to sensitive ataxia, dissociated sensory disorders, dysphagia, paresis of the extremities...

A Cavalier King Charles Spaniel dog was presented because of a 10-d history of progressive vomiting, inappetence, and lethargy, with mild neurologic signs. Fine-needle aspirates of splenic nodules seen on ultrasound were suggestive of a carcinoma. On autopsy, a disseminated neoplasm was present in the lung, spleen, and adrenal glands. Additionally, there was a Chiari-like malformation of the skull with corresponding syringomyelia of the cranial spinal cord. Histologically, the neoplasm was comprised of a pleomorphic population of round cells with a high mitotic rate...

INTRODUCTION: Patients with Klippel-Feil syndrome can present with a myriad of symptoms and imaging findings. Herein, we present a case of Klippel-Feil syndrome that was initially misdiagnosed with syringomyelia. We review this case and discuss the imaging findings. CONCLUSIONS: Neuoroschisis should be suspected in patients with Klippel-Feil syndrome and differentiated from syringomyelia.

Syringomyelia is the term given to cystic cavities in the spinal cord, most of which are associated with congenital malformations of the craniocervical junction and represent dilation of the central canal of the cord. As such, syrinxes can be considered analogous to hydrocephalus. The exact etiology of syrinx formation remains a subject of debate, but there is ample evidence that they are the result of obstruction of the normal flow of cerebrospinal fluid between the intracranial and spinal compartments. The chances that a syrinx will progress over time are much greater when they are associated with a causative lesion (Chiari malformation, tumor, infection, and trauma), but asymptomatic central canal dilation may be a stable incidental finding...

INTRODUCTION: Childhood angular kyphosis is rare, as most children are affected by a mixed kyphotic and scoliotic deformity. Published series involving a mix of kyphosis and kyphoscoliosis, pediatric and adult, congenital and acquired cases are almost exclusively authored by orthopedic surgeons, suggesting that (pediatric) neurosurgeons are not involved. CASE SERIES: We present five cases that illustrate the spectrum of angular kyphosis, and these were treated by a multidisciplinary team including child neurologist, orthopedic surgeon, and pediatric neurosurgeon as complementary partners...

OBJECTIVE Dorsal arachnoid webs (DAWs) and spinal cord herniation (SCH) are uncommon abnormalities affecting the thoracic spinal cord that can result in syringomyelia and significant neurological morbidity if left untreated. Differentiating these 2 entities on the basis of clinical presentation and radiological findings remains challenging but is of vital importance in planning a surgical approach. The authors examined the differences between DAWs and idiopathic SCH on MRI and CT myelography to improve diagnostic confidence prior to surgery...

The correlation between hydrocephalus and Chiari type I malformation (CIM) has been debated since Chiari's first descriptions of CIM but some studies have shown that CIM and hydrocephalus (HCP) could cause symptoms/disease of each other or vice versa. Recent research has found that treatment focused on hydrocephalus with ventricle enlargement also provides alleviation of CIM and even of syringomyelia. However, the lack of consensus among previous studies left unanswered the question of how endoscopic third ventriculostomy (ETV) addresses CIM and why it fails...

OBJECTIVE There has been no established animal model of syringomyelia associated with lumbosacral spinal lipoma. The research on the pathophysiology of syringomyelia has been focused on Chiari malformation, trauma, and inflammation. To understand the pathophysiology of syringomyelia associated with occult spinal dysraphism, a novel animal model of syringomyelia induced by chronic mechanical compression of the lumbar spinal cord was created. METHODS The model was made by epidural injection of highly concentrated paste-like kaolin solution through windows created by partial laminectomy of L-1 and L-5 vertebrae...

OBJECTIVE: To investigate whether posterior fossa decompression (PFD) could improve denervation of the paraspinal muscles in patients with Chiari I malformation (CMI). BACKGROUND: Paraspinal muscle denervation is one of the essential elements in the pathophysiology of CMI/syringomyelia-related scoliosis. Although PFD has been widely used for managing CMI, whether denervation of the paraspinal muscles may benefit from this neurosurgical procedure remains ambiguous...

OBJECTIVE: The authors evaluate the significance of atlantoaxial instability in the management of idiopathic syringomyelia. BACKGROUND: We recently observed that atlantoaxial dislocation can be present even when the atlantodental interval was within normal range. Atlantoaxial instability can be identified on the basis of facetal mal-alignment or even by direct observation of status of joint during surgery. Our observations are discussed in nine patients where we identified and treated atlantoaxial instability in cases that would otherwise be considered as having "idiopathic" syrinx...

REVIEW
Mark C Snoddy, Donald H Lee, John E Kuhn
Charcot arthropathy of the shoulder and elbow is a rare disease process initially described in the 1700s; however, it was not until the 19th century that physicians understood its association with other disease processes such as cervical spine pathology and diabetes. A primary complaint is painful or painless joint dysfunction, meaning the orthopedic surgeon is regularly the first physician to evaluate the patient. Frequently, the condition of these patients is misdiagnosed. Although the pathogenesis of the disease is controversial, the etiology is commonly due to syringomyelia...
