AIM To analyze retrospectively the surgical management of reducible atlantoaxial dislocation (AAD), basilar invagination (BI) and Chiari malformation (CHM) with syringomyelia through a single-stage posterior approach. MATERIAL AND METHODS Forty-three patients with reducible AAD, BI and CHM with syringomyelia underwent surgery from January 2009 to January 2013. Intraoperative restoration follo...

Background: The intramedullary pulse pressure theory would provide an explanation of the pathophysiology of idiopathic syringomyelia i.e. Syringomyelia develops where the systolic CSF passes through a regional narrowing in the subarachnoid space which leads to increase in CSF velocity and, according to the Bernoulli theorem, decrease in CSF pressure that would cause a suction effect (Venturi ef...

Post-traumatic syringomyelia was previously thought to be an infrequent but serious sequel to spinal cord injury. Clinical and CT studies have shown an incidence of between 1% and 5%, but more recently MRI has suggested an incidence of up to 22%. Twenty spinal cords have been examined after death from two days to 43 years after injury. Four had syrinxes, 20% of the series, approaching the incid...

Adhesive arachnoiditis is a rare condition, often complicated by syringomyelia. This pathologic entity is usually associated with prior spinal surgery, spinal inflammation or infection, and hemorrhage. The usual symptoms of arachnoiditis are pain, paresthesia, and weakness of the low extremities due to the nerve entrapment. A few cases have had no obvious etiology. Previous studies have reporte...

Single fibre EMG has been used to study the pattern of upper limb motor involvement in syringomyelia. Biceps brachii, extensor digitorum communis (EDC) and first dorsal interosseous muscles (1stDI) representing C5/6, C7/8 and C8/T1 segments, were studied. In the biceps the fibre density was slightly increased in most patients, in EDC it was about twice the normal and in the 1stDI it was about t...

Six cases of syringomyelia associated with intramedullary tumor were examined by metrizamide myelography and delayed computed tomography. All cases showed opacification of syringomyelic cavities 7-24 hr after myelography. This finding suggests that metrizamide can pass through the cord substance from the subarachnoid space into a syrinx cavity in noncommunicating types of syringomyelia. It supp...

Neuromyelitis optica spectrum disorder (NMOSD) is an idiopathic inflammatory demyelinating disease characterized by longitudinally extensive transverse myelitis (LETM) and optic neuritis. This article reported a case of a 58-year-old women initially presented with asymmetric tetraparesis and binocular vision diminution. MRI (full name please) showed the longitudinal syringomyelia from C3 to T1 ...

Syringomyelia is characterized by slow progression; the joints involved most frequently are the shoulders and elbows. Neuropathic arthropathy of the hand is quite rare. Herewith, we present a case of neuropathic arthropathy (NA) of the joints in the upper limb secondary to Syringomyelia. Atypical features of the case included NA of the shoulder, elbow and metacarpophalengeal joint in the same u...

Idiopathic transverse myelitis is a monophasic demyelinating disease of the central nervous system (CNS) and its recurrence is a rare entity. Existence of syringomyelia in the spinal cord in inflammatory CNS disease is not usually encountered. This case study describes a 45-year-old man who was admitted with features of a cervical demyelinating disease. The history of the patient indicated that...
