Dorota Tassigny, Basel Abu-Serieh, Daniella Tsague Fofe, Jacques Born, Germain Milbouw
BACKGROUND AND IMPORTANCE: Syringomyelia is a progressive cerebrospinal fluid disorder which can lead to irreversible spinal cord injury. To date, the optimal management of syringomyelic cavities remains controversial. Multiple studies have emphasized the importance of the cranio-cervical decompression or shunting procedures. However, excepted for syrinx related to Arnold Chiari malformation, nearly half of patients need to be re-operated. The purpose of the present study was to describe a simple and efficient surgical technique and to report the long-term radio-clinical outcomes...

A previously well 30-year-old woman presented at 17:30 with a sudden onset of dizziness, ataxia and headache. She was initially investigated with a CT scan of the brain and lumbar puncture, which yielded no diagnosis. Subsequent MR scan revealed multiple posterior circulation infarcts, along with a previously undiagnosed Arnold-Chiari 2 malformation with an associated syrinx of her cervical and thoracic spine. The infarct involved one of the herniated cerebellar tonsils. Oedema of an infarct in the herniated tonsils caused compression of the medulla at the foramen magnum, with associated neurological symptoms including Lhermitte's phenomenon and headache on valsalva manoeuvre...

We present a case of a 17-year-old Hispanic male with Arnold-Chiari Type 1 [AC-Type 1] with syringomyelia, status post decompression, who complains of exercise intolerance, headaches, and fatigue with exertion. The patient was found to have diurnal hypercapnia and nocturnal alveolar hypoventilation. Cardiopulmonary testing revealed blunting of the ventilatory response to the rise in carbon dioxide (CO2) resulting in failure of the parallel correlation between increased CO2 levels and ventilation; the expected vertical relationship between PETCO2 and minute ventilation during exercise was replaced with an almost horizontal relationship...

INTRODUCTION: Surgery for craniovertebral junction (CVJ) abnormalities like atlantoaxial dislocation (AAD) with or without basilar invagination (BI) and/or with or without associated Arnold-Chiari malformation (ACM) cause high cervical myelopathy. Occasionally, mechanical factors such as inadequate canal decompression, torticollis, and/or scoliosis may lead to lack of improvement following the primary surgery. Also, implant-related factors requiring its revision/removal or surgical site infections may cause patient to undergo resurgery...

INTRODUCTION: Bilateral vocal cord palsy is a condition which has many causes (Gupta et al., 2012) [1]. Syringomyelia is an uncommon condition which describes the formation of fluid filled cavity, occupying the spinal cord (Chang, 2003) [2]. It rarely manifests itself as subacute onset of stridor. PRESENTATION OF CASE: We present the case of a three year old female who presented for evaluation of her speech and language delay, when incidentally it was made note of her loud breathing which had previously been managed as bronchiolitis by her general practitioner...

INTRODUCTION: We report a case of an adolescent sustaining bilateral femoral neck fractures due to a first time epileptic seizure, as a result of expansion of his known syrinx. CASE REPORT: A 19-year-old patient suffering from hypophosphatasia (HPP), Arnold-Chiari malformation, and a ventriculoperitoneal shunt sustained a trivial fall with profound pain and an inability to mobilize. Radiographs demonstrated a right-sided Garden-4 femoral neck and left-sided multi-fragmentary intracapsular/extracapsular fractures...

To present and describe an unusual case of spinal instability after craniocervical spinal decompression for a type-1 Chiari malformation. Type-1 Chiari malformation is a craniocervical disorder characterized by tonsillar displacement greater than 5 mm into the vertebral canal; posterior fossa decompression is the most common surgical treatment for this condition. Postoperative complications have been described: cerebrospinal fluid leak, pseudomeningocele, aseptic meningitis, wound infection, and neurological deficit...

SPOndylar and NAsal changes, with STRIations of the Metaphyses (SPONASTRIME) dysplasia (SD) is a dwarfing autosomal recessive syndrome, characterized by a variety of clinical and radiographic features, which form the basis for diagnosis. We describe the presentation of an Arnold Chiari malformation in a patient with a clinical diagnosis of SD. The malformation was successfully treated by decompression of the foramen magnum and elevation of the cerebellum, with complete resolution of pain.We report a rare case of Arnold Chiari malformation in a patient presenting with clinical and radiographic features strongly suggestive of SD and be successfully treated...

Charcot arthropathy is a progressive, chronic and degenerative destruction of one or several joints caused by a central or peripheral neurological disorder. Approximately 25 % of the patients with syringomyelia develop this arthropathy located in the upper limb in 80 % of the cases. An early etiological diagnosis is essential to begin the treatment of the underlying neurological disorder. Afterwards, a conservative treatment of the arthropathy is preferred. We report the story of a patient with an arthropathy of the left shoulder due to Arnold-Chiari's malformation of type I with syringomyelia...

BACKGROUND: Though several studies have reported the incidence of intraspinal neural axis abnormalities in infantile and juvenile "presumed idiopathic" scoliosis, there has been a varying prevalence ranging from 11.1 to 26.0% based on a limited sample size. Therefore, such inconclusive findings have resulted in some questions on the MRI-associated role in the management of these patients. We aimed to investigate the prevalence and distribution of intraspinal anomalies in the infantile and juvenile patients with "presumed idiopathic" scoliosis and to explore the radiographic and clinical indicators with large sample size...

A 3-yr-old male captive bobcat (Lynx rufus) presented with chronic ataxia and right-sided head tilt. Magnetic resonance imaging (MRI) revealed cerebellar crowding and compression consistent with Chiari-like malformation. The clinical signs did not improve after surgical occipital craniectomy, and 2 mo postoperatively a second MRI showed hydromyelia and continued cerebellar compression. The bobcat was euthanized, and necropsy showed chronic focal cerebellar herniation and chronic multifocal atlanto-occipital joint osteophyte proliferation...

OBJECTIVE: To evaluate the possible correlation and the true incidence between Neurofibromatosis type 1 and Arnold-Chiari malformation type I. MATERIALS AND METHODS: We reviewed all clinical charts, neurological consultations and MRI scans of 428 NF1 patients followed by 1994 to 2014 in our Department. NF1 patients in our clinic are seen usually every year by both the dermatologist and the neurologist. All patients also undergo a brain and spinal cord with the same 1...

AIM: Chiari malformation is characterized by herniation of the cerebellar tonsils into the foramen magnum, which leads to disturbance of CSF circulation through the craniovertebral junction. Orthostatic stress, which leads to the movement of SCF through the craniovertebral junction, is an adequate method to detect these disorders. It is accompanied by changes in the intracranial pressure, affecting the cerebrovenous orthostatic reactivity (CVOR), which is noninvasively assessed in patients with Chiari malformation...

INTRODUCTION: The presentation of a down-beating nystagmus force to discard vascular pathology of brain and cervical joint with magnetic resonance imagine (MRI). Recent studies support the low profitability of this study and is subjected that this oculomotor sign has a peripheral origin especially when the patient has a benign paroxysmal positional vertigo (BPPV) with affection of the superior semicircular canal. AIM: To evidence the profitability of MRI in a population of patients with positional down-beating nystagmus...

The diagnosis of an abnormal fetal posterior fossa is usually done during the second trimester scan. However, some forms of open spina bifida with Arnold-Chiari malformation can be detected from the first trimester ultrasound with a precise examination of the posterior fossa and intracranial translucency. Furthermore, other abnormalities of the posterior fossa such as cystic malformations also seem to be accessible to early detection. This work detailed the possible usual and unusual aspects of the posterior fossa individualized during the first trimester ultrasound scan...
