BACKGROUND With increasing use of magnetic resonance imaging (MRI), underlying syringomyelia is increasingly found in patients with presumed idiopathic scoliosis. To determine the indications for MRI in the differential diagnosis of scoliosis, several clinical characteristics of syringomyelia have been reported. Neurological signs, particularly abnormal superficial abdominal reflex (SAR), are i...

Numerous experimental observation and clinical researches demonstrated that the majority of the forms of syringomyelia are found in combination with inherent or acquired hindbrain abnormalities [1,2]. Although hydrodynamic disorders play an important role in the pathogenesis, these forms of syringomyelia, several aspects of this disease are dif icult to explain only on the basis of hydrodynamic...

The pathogenesis of most cases of syringomyelia remains obscure although a modification of the hydrodynamic theory of Gardner allows a logical surgical approach to treatment. Data are presented confirming a high incidence of traumatic birth in patients with syringomyelia who have a Chiari malformation or basal arachnoiditis, but demonstrating no increase in traumatic birth in patients with the ...

Spinal deformity is an important clinical manifestation of Chiari I malformation (CM-I) and syringomyelia. Here we report the result of an 8-year follow-up of a 13-year-old girl with severe scoliosis associated with Chiari malformation and a large syringomyelia. The patient presented at our hospital at the age of 13 with a 68° scoliosis. Magnetic resonance imaging showed Chiari malformation and...

Occasionally, a posterior fossa arachnoid cyst can induce compression of the spinal cord and cause syringomyelia. Here, we report the case of a 29-year-old man with both progressive shoulder pain and gait disturbance, who was found to have a huge retrocerebellar arachnoid cyst associated with syringomyelia. Accordingly, posterior fossa decompression and arachnoid cyst excision were performed. P...

BACKGROUND Medullary elevation (ie, medullary kinking) at the craniocervical junction (CCJ) is reported in dogs with Chiari-like malformations (CM), but its diagnostic criteria and clinical relevance are unclear. OBJECTIVE To describe the position of the medulla at the CCJ in mature cavalier King Charles spaniels (CKCS), and evaluate its relationship with clinical status and the presence of s...

Syringomyelia is an important morbidity source in Cavalier King Charles Spaniels. Although abnormal cerebrospinal fluid (CSF) flow secondary to Chiari malformations is thought to cause syringomyelia in humans, this relationship is unknown in dogs. We used phase-contrast magnetic resonance (MR) imaging to evaluate CSF flow in dogs. Fifty-nine Cavalier King Charles Spaniels were assigned a neurol...

In the pre-MR era syringomyelia often presented late, as a crippling neurological disorder. Today, most cases are diagnosed earlier, with less pronounced deficits. We therefore new challenges, including understanding significance of various presenting symptoms, knowing when surgery might help and being aware other treatments that could benefit someone living effects syringomyelia, or its underl...

BACKGROUND Syringomyelia is a fluid-filled tubular cavity within the spinal cord. The exact pathophysiology of syringomyelia remains complex and uncertain. MATERIAL We present a case of resolution of cervical syringomyelia after cervical disc operation in a follow-up time of 6 months. CONCLUSION Restoration of cerebrospinal fluid flow dynamics between the syrinx and the subarachnoid space v...

Background: Chiari Malformation type 1 (CM-I) is a congenital disease characterized by downward decent of the cerebellar tonsil and crowding in the craniocervical junction area. There are still obvious controversies for the optimum surgical strategy for Chiari malformation type 1 especially if associated with syringomylia. Objectives: to determine the results of bony decompression with and with...
