BACKGROUND: A syrinx is a fluid-filled cavity within the spinal cord. They can lead to a variety of symptoms, including limb weakness and back pain. Incidental finding of syringomyelia provides a challenge for clinicians due to the wide variety of possible symptoms. In military aviation, neurological findings in pilots can result in extensive investigation that can lead to potentially invasive management. Conversely, the potential for chronic progression of a spinal syrinx and subsequent neurological deterioration makes early identification critical...

BACKGROUND: Scoliosis patients with associated syringomyelia are at an increased risk of neurological injury during surgical deformity correction. The syrinx is therefore often addressed surgically prior to scoliosis correction to minimize this risk. It remains unclear if the presence of a persistent central canal (PCC) within the spinal cord also poses a similar risk. The aim of this study is to determine whether there is any evidence to suggest that patients with a PCC are also at a higher risk of neurological injury during surgical scoliosis correction...

INTRODUCTION: Acquired Chiari malformation and associated syringomyelia have been previously described following lumbar puncture/drainage, lumboperitoneal shunts, and spontaneous CSF leakage. In addition to these etiologies, space-occupying lesions such as meningiomas, epidermoid cysts, medulloblastomas, and arachnoid cysts are rare causes of acquired Chiari malformation and syringomyelia. We report a rare case of colloid cyst with hydrocephalus causing secondary Chiari malformation with syringomyelia...

BACKGROUND: Chiari-like malformation (CM) and syringomyelia (SM) are widely reported in Cavalier King Charles Spaniels and Griffon Bruxellois dogs. Increasing evidence indicates that CM and SM also occur in other small and toy breed dogs, such as Chihuahuas. OBJECTIVES: To describe the presence of SM and craniocervical junction (CCJ) abnormalities in Chihuahuas and to evaluate the possible association of CCJ abnormalities with SM. To describe CM/SM-related clinical signs and neurologic deficits and to investigate the association of CM/SM-related clinical signs with signalment, SM, or CCJ abnormalities...

INTRODUCTION: Syringomyelia is a disorder in which a cyst, or syrinx, develops within the spinal cord. Historically, syringomyelia in post-traumatic spinal cord injury has been uncommon; however, its diagnosis has been increasing due to the advances in medical technology. Syringomyelia that involves the entire spinal cord, or holocord, is rare after traumatic spinal cord injury, with only a few cases reported in the literature. CASE PRESENTATION: We present a case of a 57-year-old male who had a motorcycle accident 30 years ago resulting in a spinal cord injury, who presented a rapid decline in the function of his left upper extremity...

Magnetic resonance imaging (MRI) is a method of choice in diagnosing nervous system disorders. This paper presents the results of a study where selected segments of the canine spine were examined by low-field MRI in 112 patients. Images of pathological changes were obtained in spin echo (SE), fast spin echo (FSE) and hybrid contrast enhancement (3D HYCE) sequences. The cervical region of the spinal cord (C1-C5) was examined in 32 patients, the cervicothoracic region (C6-Th2)- in 14 patients, the thoracolumbar region (Th3-L3) - in 23 patients, and the lumbosacral region (L4-S3) - in 43 patients...

BACKGROUND: Although cervical spondylosis is extremely common, only few cases with associated syrinx have been reported. Depending on review of two large data bases, we report this case series. In addition, we evaluated the posterior decompression as the management option in treatment of this rare condition. MATERIALS AND METHODS: Data of all cases with cervical spondylosis and canal stenosis that sought medical advice or needed decompressive laminectomy/laminoplasty between the years 2006 and 2015 were checked in manually...

OBJECTIVE: Cranio-cervical junction arachnoiditis (CCJA) is an uncommon cause of syringomyelia. The pathophysiology of syrinx formation is uncertain and the appropriate management unclear. A series of cases is reported to demonstrate variations in etiology, uniformity of functional CSF obstruction at the foramen magnum, and results of surgical intervention. METHODS: We retrospectively analyzed the clinical and radiological features of a consecutive series of patients treated for syringomyelia related to CCJA...

BACKGROUND: The technique for decompression of Chiari type I malformation relies on open exposure of craniocervical junction for suboccipital craniectomy and upper cervical laminectomy with or without duraplasty. There is no detailed technical report of a minimally invasive approach for Chiari decompression in adults. OBJECTIVE: To describe a mini-open technique for decompression of Chiari type I malformation (including duraplasty) in adults. METHODS: Six consecutive adult patients with symptomatic Chiari type I malformation underwent decompression through a 3 to 4 cm midline incision via a speculum retractor...

BACKGROUND: Feline infectious peritonitis (FIP) is the most common infectious central nervous system (CNS) disease in the cat and is invariably fatal. Improved means of antemortem diagnosis is required to facilitate clinical decision making. Information regarding the magnetic resonance imaging (MRI) findings of neurologic FIP currently is limited, resulting in the need for better descriptions to optimize its use as a diagnostic tool. OBJECTIVE: To describe the clinicopathologic features and MRI findings in cases of confirmed neurologic FIP...

BACKGROUND: The foramen magnum provides a transition between fossa cranii posterior and canalis vertebralis. Medulla oblongata, arteria vertebralis and nervus accessorius spinal part pass through the foramen magnum. In this study, we aimed to make the morphometric measurements of the foramen magnum on CT and to determine the feasibility of sex determination based on these measurements. Besides sex determination, from a clinical aspect, it is important to know the measurements of the foramen magnum in the normal population in terms of diseases characterized by displacement of the posterior fossa structures through foramen magnum to upper cervical spinal canal like Chiari Malformations and Syringomyelia...

BACKGROUND: Approximately 30% of patients treated by foramen magnum decompression (FMD) for Chiari I-associated-syringomyelia will show persistence, recurrence, or progression of the syrinx. OBJECTIVE: This study evaluates the clinical and radiological outcome of syringo-subarachnoid shunt (SSS) as the treatment for persistent syringomyelia after FMD. METHODS: Data was collected retrospectively. The primary outcome measurement was neurological function (assessed with the Modified Japanese Orthopedic Association (mJOA) scale)...

BACKGROUND: Cell transplantation with autologous bone marrow-derived mesenchymal stromal cells (MSCs) seems to be a therapeutic promise for patients with established spinal cord injury (SCI), achieving improvement in their quality of life, but there is no experience about the application of this type of cell therapy in patients suffering posttraumatic syringomyelia. OBJECTIVE: To study the possible utility of cell therapy with autologous MSCs in posttraumatic syringomyelia...

The gene DST encodes for the large protein BPAG1 involved in hemidesmosomes. Its alternative splicing gives rise to tissue-enriched isoforms in brain, muscle, and skin. The few patients described so far with bi-allelic mutations in the DST gene have either a skin phenotype of epidermolysis bullosa simplex or a neurological phenotype. Here, we report a 17-year-old female individual presenting with a more complex phenotype consisting of both skin and neuronal involvement, in addition to several previously unreported findings, such as iris heterochromia, cataract, hearing impairment, syringomyelia, behavioral, and gastrointestinal issues, osteoporosis, and growth hormone deficiency...

BACKGROUND: Chiari Malformation Type I is a hindbrain abnormality characterized by cerebellar tonsils descent beneath the foramen magnum, frequently associated with symptoms or brainstem compression, impaired cerebrospinal fluid circulation and syringomyelia. Foramen magnum decompression represents the most common way of treatment. Rarely, subdural fluid collection and hydrocephalus represent postoperative adverse events. The treatment of this complication is still debated, and physicians sometimes are faced with the doubt of when undergoing diversion surgery and when more conservative managements...

Dynamic MR imaging was used to evaluate a cervical syrinx in an adolescent boy with an associated hindbrain herniation. Null artifacts were present on one of the sequences that allowed simultaneous high-resolution visualization of syrinx fluid motion and the anatomy of the syrinx walls. A brief review of the theories of syrinx formation and propagation is provided with a comment on why the Williams "slosh" theory of syrinx progression is supported by our unique imaging.
