Experimental syringomyelia

The relationship between intraventricular and intrasyrinx pressures

Peter Hall, Michael Turner, Steven Aichinger, Phillip Bendick and Robert Campbell

T he idea that the pathophysiology of syringomyelia is related to congenital or acquired anomalies of the craniocervical junction with interference of cerebrospinal fluid (CSF) flow is accepted by many neurosurgeons. Unfortunately, no single surgical approach, whether posterior fossa decompression, ventricular shunting, myelotomy, or terminal ventriculostomy, has produced uniformly successful results in these patients. Underlying the limitations of our clinical management is an incomplete knowledge of the mechanisms responsible for enlargement of the syrinx

S yringomyelia is a malformation marked by the presence of a cavity within the spinal cord. 8 In 75% of cases, it is associated with Arnold-Chiari type I malformation. 17 Several theories on the pathogenesis of syringomyelia 2, 3, 12, 25, 27 have been put forward but those that have gained widest credence are the hydrodynamic theory of Gardner 12 and the cerebrospinal fluid (CSF) dissociation theory of Williams. 27 Diagnostic imaging has made the identification of syringomyelia and malformations of the craniovertebral junction much easier. 5, 9, 10, 23

Acute presentations of syringomyelia

Report of three cases

Eric L. Zager, Robert G. Ojemann and Charles E. Poletti

T he traditional definition of syringomyelia is a chronic, progressive degenerative disorder of the spinal cord characterized by dissociated sensory loss and brachial amyotrophy with pathological evidence of central cord cavitation. 1 In its most severe form, neuropathic joints and painless ulcers may develop. The clinical features of the syndrome are highly variable, usually with an insidious onset, a course of many years, and an unpredictable pace of progression. In the most comprehensive discussion of this topic in the literature, Barnett, et al. , 5

Surgical treatment of syringomyelia

Favorable results with syringoperitoneal shunting

Nicholas M. Barbaro, Charles B. Wilson, Philip H. Gutin and Michael S. B. Edwards

T he natural history of syringomyelia is highly variable. Some patients improve or stabilize without surgery, while others deteriorate even with the most aggressive intervention. 2, 3, 18 Several different operations have been advocated for the treatment of syringomyelia, including posterior fossa decompression with 2, 4, 9, 10 or without 8, 9, 19, 23, 28, 29 closure of a patent central canal, laminectomy with syringostomy, syrinx to subarachnoid (SSA) shunting, 25, 28, 30 terminal ventriculostomy, 11 ventriculoatrial shunting, 16 and syringoperitoneal

Chiari I malformation with syringomyelia

Evaluation of surgical therapy by magnetic resonance imaging

Ulrich Batzdorf

T he advent of new imaging techniques in the past decade (in particular, computerized tomographic scanning with injection of water-soluble contrast medium and magnetic resonance (MR) imaging) has greatly facilitated the diagnosis of Chiari I malformation and associated syringomyelia. Indeed, MR imaging has now become the optimal technique, since it is noninvasive and permits simultaneous studies of the brain, craniocervical junction, and spinal cord. 2 As a result, this disease complex, once thought to be quite rare, is now being diagnosed with increased

W ith a prevalence of 8.4 cases per 100,000 population, approximately 21,000 Americans have syringomyelia, a disorder in which a cyst forms within the spinal cord, resulting in myelopathy. 6 Symptoms of paralysis, sensory loss, and chronic pain commonly develop during the second through fifth decades of life. The natural history of syringomyelia is typically one of gradual, stepwise neurological deterioration extending over many years. 5 Syringomyelia is usually associated with an inferior position of the cerebellar tonsils through the foramen magnum: the

T hecoperitoneal shunting is now a well-established technique for treating communicating hydrocephalus. It has also proved its usefulness in cases of cerebrospinal fluid (CSF) rhinorrhea, to arrest an intractable CSF leak, and in benign intracranial hypertension to prevent impending loss of vision. We have found this technique rewarding in three consecutive cases of syringomyelia treated between January and April, 1990, and would like to place our experience on record for future evaluation of the technique. All three patients presented clinically with a

T here is still considerable controversy about the indications for surgery and the methods of surgical treatment in syringomyelia. 4, 10 Although the etiology and natural history of this disease are quite variable, 10, 16 surgical treatment has usually been recommended for patients with rapidly deteriorating neurological function. Gardner 4 has strongly advocated the hydrodynamic theory for the pathogenesis of syringomyelia, and decompression of the hind-brain with closure of the obex has been the surgical treatment of choice in many centers. As a result

compression and syringomyelia has been commonly mentioned in relation to Chiari malformations, particularly those presenting in adulthood. 1, 11, 12 The occurrence of syringomyelia with Paget's disease has rarely been mentioned, however, and no individual case report can be found in which this association has been described. We present such a case, and give details of the radiographic appearance and the operative treatment. Case Report This 64-year-old woman had suffered from Paget's disease for more than 10 years. At this admission, she presented with a 3-year

M any case reports have been published on syringomyelia complicated by Chiari malformation. However, it is quite rare to find the syrinx extending to the pons or to an even higher level. 1–3 Only one case report, published by Valentini, et al. , 4 has described the in vivo radiological appearance of a syrinx extending to the basal ganglia. The authors called the cerebral syrinx “syringocephalia.” To our knowledge, to date no record has presented sagittal and coronal magnetic resonance (MR) images showing a syrinx of this type. In this publication, the
