BACKGROUND: A candidate with paraplegia contacted the Institute of Aviation Medicine, Oslo, requesting a medical examination and medical certification for flying back seat on an F-16 Fighting Falcon. Thorough aeromedical examinations, including specialist evaluations, were initiated for the final decision to be made. CASE REPORT: Almost 13 yr earlier the candidate had acquired spinal cord damage at neurological level L1 after falling 4 m (13 ft) from out of a window...

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...

BACKGROUND: Tectal gliomas (TG) are slow-growing tumors and generally present with features of increased intracranial pressure. CASE DESCRIPTION: We describe an unusual case of a young girl who presented with clinical triad of obesity, primary amenorrhea and central cord syndrome. The radiology unveiled a pentad of hydrocephalus, empty sella, suprapineal recess diverticulum, secondary Chiari malformation and cervical syringomyelia, masking a relatively obscure tectal plate glioma...

OBJECT: To examine the role of race, gender, and socioeconomics on presentations and outcomes of adult Chiari 1 malformations. METHODS: The charts of 638 adult patients with Chiari 1 malformations were reviewed, and 287 patients were included. Race, gender, insurance status, symptoms, depth of cerebellar tonsillar herniation, and presence of syringomyelia were examined as covariates in multivariate logistic regression models to identify independent predictors of presentation and outcome...

Neuropathic Arthropathy or Charcot joint is a progressive, destructive arthritis that is associated with an underlying neurological disorder. We present a case of a 30 year-old male who, three years prior, had ruptured his right distal biceps tendon with subsequent development of a deep infection. At representation, the patient's clinical picture was consistent with the re-emergence of a deep elbow infection. Laboratory testing found no evidence of infection. Magnetic Resonance Imaging (MRI) of the patient's spine revealed a syringomyelia and a NA was diagnosed...

Syringomyelia is a condition of the spinal cord in which a syrinx, or fluid-filled cavity, forms from trauma, malformation, or general disorder. Previous work has shown that in noncanalicular syringomyelia irregular flow and pressure conditions enhance the volumetric growth of syrinxes. A better understanding of the underlying molecular pathways associated with syrinx formation will unveil targets for treatments and possibly prevention of syringomyelia in the future. In this study, we performed an established surgical induction of a syrinx using quisqualic acid and kaolin injections in rats to characterize the injury at the molecular level by RNA sequencing and metabolomics techniques at three and six weeks post-injury...

Syringomyelia (a spinal cord cyst) usually develops as a result of conditions that cause cerebrospinal fluid (CSF) obstruction. The mechanism of syrinx formation and enlargement remains unclear, though previous studies suggest that the fluid enters via the perivascular spaces (PVS) of the penetrating arteries of the spinal cord, and that alterations in the CSF pulse timing and pressure could contribute to enhanced PVS inflow. This study uses an idealised computational model of the PVS to investigate the factors that influence peri-arterial fluid flow...

OBJECTIVE: MRI has highly changed the assessment of post-traumatic syringomyelia (PTS), roughly estimated at 30% nowadays. Times to onset (TTO) symptoms are random. This case report describes how hyperhidrosis appeared and revealed PTS diagnosis. OBSERVATIONS: Mr M., 43-year-old, is rehabilitation inpatient after T10 AIS A spinal cord injury (SCI). Three months after this event, Mr M complains of acute hyperhidrosis crisis always located below the injury, which can occur at any time of the day, particularly when he moves...

STUDY DESIGN: A retrospective observational study. OBJECTIVE: To describe specificities of pregnancy in a traumatic spinal cord-injured (SCI) population managed by a coordinated medical care team involving physical medicine and rehabilitation (PMR) physicians, urologists, infectious diseases' physicians, obstetricians and anaesthesiologists. SETTING: NeuroUrology Department in a University Hospital, France. METHODS: All consecutive SCI pregnant women managed between 2001 and 2014 were included...

OBJECTIVE: The pathophysiology of idiopathic Chiari malformation (CM) type 1 is disturbance of free cerebrospinal fluid (CSF) flow and restoration of normal CSF flow is the mainstay of treatment. Additional migration of the medulla oblongata in pediatric patients is referred to as CM type 1.5, but its significance in adult patients is unknown. This study is to compare surgical outcomes of adult idiopathic CM type 1.5 with that of type 1. METHODS: Thirty-eight consecutive adult patients (M : F=11 : 27; median, 33...

An existing axisymmetric fluid/structure-interaction model of the spinal cord, pia mater, subarachnoid space and dura mater in the presence of syringomyelia and subarachnoid space stenosis was modified to include porous solids. This allowed investigation of a hypothesis for syrinx fluid ingress from cerebrospinal fluid. Gross model deformation was unchanged by the addition of porosity, but pressure oscillated more in the syrinx and the subarachnoid space below the stenosis. The poroelastic model still exhibited elevated mean pressure in the subarachnoid space below the stenosis, and in the syrinx...

BACKGROUND: Tumefactive multiple sclerosis (MS) is an unusual variant of demyelinating disease characterized by lesions with pseudotumoral appearance on radiological imaging mimicking other space-occupying lesions, such as neoplasms, infections, and infarction. Especially when the patient's medical history is incompatible with MS, the differential diagnosis between these lesions constitutes a diagnostic challenge often requiring histological investigation. An older age at onset makes distinguishing tumefactive demyelinating lesion (TDL) from tumors even more challenging...

OBJECTIVE A subset of patients with Chiari I malformation demonstrate patent subarachnoid spaces around the cerebellum, indicating that reduced posterior fossa volume alone does not account for tonsillar descent. The authors distinguish two subsets of Chiari I malformation patients based on the degree of "posterior fossa crowdedness" on MRI. METHODS Two of the coauthors independently reviewed the preoperative MR images of 49 patients with Chiari I malformation and categorized the posterior fossa as "spacious" or "crowded...

Neuropathic arthropathy of the elbow is a rare condition, which is disabling and difficult to treat. Initial treatment is conservative and arthrodesis is rarely indicated. We describe an unusual case of progressive unilateral elbow swelling in a 37-year-old female domestic helper. She was found to have neuropathic arthropathy of her right elbow secondary to underlying cervico-thoracic syringomyelia. She underwent decompression of the syringomyelia before underdoing elbow fusion. Her elbow was initially immobilized in a cast to minimize bony fragmentation and soft tissue swelling...

INTRODUCTION: Syringomyelia is defined as a cavity containing cerebrospinal fluid inside the spinal cord. AIM: To describe the clinical characteristics of a series of patients with syringomyelia, as well as its diagnosis and treatment. PATIENTS AND METHODS: We conducted a retrospective descriptive study by reviewing the medical records at our centre. RESULTS: We reviewed 25 patients diagnosed with syringomyelia. In five cases, the diagnosis was reached casually, and eight of them presented a previous severe pathology (tumour, bone or vascular)...
