BACKGROUND: Spinal dural arteriovenous fistula (DAVF) is a rare disease and multiple concurrent lesions are extremely rare. Such multiple spinal DAVFs have similar outflow routes at neighboring levels. However, there have been no reported cases of remote lesions of multiple spinal DAVFs. The authors herein report a case of double synchronous cervical and sacral DAVFs. CASE DESCRIPTION: A 56-year-old man with no prior history of disease presented with progressive myelopathy, and spinal magnetic resonance imaging (MRI) showed extensive edema of the spinal cord from the conus to T7...

OBJECTIVE: Clinical routine shows an increasing admission rate of elderly patients suffering from SAH. We retrospectively compared patients aged 70-79 and over 80 years (80+). Aim of the study was to identify differences in outcome and prognostic factors to better anticipate clinical course and therefore treat this special subgroup better. METHODS: Patients were entered into a prospectively collected database. Between 1999 and 06/2014 191 patients suffered from SAH and aged ≥70 years...

BACKGROUND: In multilevel degenerative conditions posterior approaches are often preferred, but anterior approaches provide comparable clinical results and better alignment. Anterior plating entails higher rates of soft tissue injuries and dysphagia, particularly in multilevel cases. This study evaluates efficacy and safety of zero-profile devices in three and four-level ACDF, analyzing patients' clinical and radiological long-term outcome. METHODS: We prospectively enrolled 24 patients with cervical spondylotic myeloradiculopathy (CSM), who underwent three and four-level ACDF with Zero-P device...

BACKGROUND: Spontaneous intracerebral hemorrhage may arise from underlying abnormalities including aneurysms. Computed tomography angiography (CTA) is widely used for the detection of possible underlying causes, which is important since it may have immediate therapeutic consequences. In addition, CTA is used to detect the so-called "spot sign", indicating active hemorrhage which carries a worse prognosis. CTA is, however, a snapshot in time. Four-dimensional CTA (4D-CTA) is a dynamic type of imaging and has emerged as a valuable imaging technique for different neurovascular disorders...

BACKGROUND: Autoimmune hypothalamitis, which is among the causes of acquired central diabetes insipidus, has been described very rarely in the literature. This condition is probably provoked by the production of anti-vasopressin secreting cells antibodies and anti-hypothalamus antibodies, and is often associated with pituitary or polyendocrine autoimmunity. Correct diagnosis and immediate treatment are essential in order to avoid the progression of the pathological process. CASE DESCRIPTION: A woman diagnosed with central diabetes insipidus 12 year ago, suffering from panhypopituitarism and mild memory deficit came to our attention...

BACKGROUND: Radiosurgery is a valuable option to treat arteriovenous malformations. There are correlations between some morphological nidal features and final results, and the benefits of preradiosurgical embolization have not been well established thus far. METHODS: Analysis of a longitudinal cohort of 47 consecutive patients who underwent radiosurgery with or without previous embolization. Embolizations were performed exclusively with n-butyl cyanoacrylate. Radiosurgery was delivered either as a single or divided in up to 5 equal fractions...

OBJECTIVE: We conducted a survey to understand how specific pathologic features on MRI influence surgeons toward an anterior or posterior surgical approach in Degenerative Cervical Myelopathy (DCM) . METHODS: A questionnaire was sent out to 6,179 AOSpine International members via email. This included 18 questions on a 7-point Likert scale regarding how MRI features influence the respondent's decision to perform an anterior or posterior surgical approach. Influence was classified based on the mean and mode...

BACKGROUND: Neurofibromatosis type 1 (NF1) is a rare disease with an incidence of one in every 3000 births. Numerous studies have focused on the main function of NF1 as a tumor suppressor, while few have examined the cerebrovascular abnormalities observed in patients with NF1. It is worth noting that intracranial aneurysms are uncommon in this condition. CASE DESCRIPTION: We report a case of NF1 with a dissection of the distal segment of the superior cerebellar artery...

OBJECTIVES: There is no standardized approach to assess and manage perioperative neurologic deficit (PND) in patients undergoing spinal surgery. This survey aimed to evaluate the awareness and usage of clinical practice guidelines (CPGs) as well as investigate how surgeons performing spine surgeries feel about and manage PND, and how they perceive the value of developing CPGs for the management of PND. METHODS: An invitation to participate was sent to the AOSpine International community...

REVIEW

Obesity is an important consideration in neurosurgical practice. 28.3% of Australian adults are obese and it is estimated that over two-thirds of Australia's population will be overweight or obese by 2025. This review of the effects of obesity on neurosurgical procedures demonstrated that, in patients undergoing spinal surgery, an increased BMI is a significant risk factor for surgical site infection, venous thromboembolism, major medical complications, prolonged length of surgery and increased financial cost...

Aspirin has been implicated in the postoperative management of moyamoya disease (MMD) in order to avoid bypass failure and decrease the incidence of subsequent stroke. However, the effect of it has not been completely determined yet. In this study, we retrospectively reviewed data of 184 adult patients (197 hemispheres) presented with ischemic-onset moyamoya disease that had undergone direct or combined revascularization in our hospital, to clarify the effect of postoperative aspirin therapy in the management of moyamoya disease...

OBJECTIVE: We analyzed a case of medulloblastoma with atypical dynamic imaging changes retrospectively to summarized the atypical MRI features of medulloblastoma by reviewing the literature. METHODS: One atypical case of medulloblastoma in the cerebellar hemisphere confirmed by pathology was analyzed retrospectively, and the literature about it was reviewed. RESULTS: The radiologic findings of the patient were based on three examinations. The first examination showed that the cortex of the bilateral cerebellar hemisphere had diffuse nodular thickening, with a high signal on DWI imaging and significant enhancement...

BACKGROUND: Injury to the infraclavicular brachial plexus is an uncommon but serious complication of shoulder dislocation. This work aims to determine the effectiveness of operative treatment in patients with this type of injury. METHODS: Thirty-three patients (26 males,7 females; mean age 45 years 3 months) treated operatively for brachial plexus injury resulting from shoulder dislocation between the years 2000-2013 were included in this retrospective case series...

PURPOSE: Hemodynamics in cerebral aneurysms is currently investigated towards its clinical efficacy using non-standardized computational simulation techniques. At the same time, flow patterns and velocities are accessible by 4D phase contrast magnetic resonance imaging (4D pcMRI). Complexity of protocol design and imaging duration has limited the use of this technique in clinical imaging. A new approach is presented to overcome these limitations. MATERIAL AND METHODS: 3D replicas of two cerebral aneurysms were fabricated by fused deposition prototyping (3D printing) and imaged using 4D pcMRI while connected to an MRI compatible continuous flow loop...

BACKGROUND: Several surgical approaches for the treatment of pathologies of the craniovertebral junction (CVJ) and high cervical regions have been reported. For the best postoperative results, selection of a surgical route to treat such pathologies should be based on a complete understanding of the approach. CASE DESCRIPTION: Here, we describe the case of a 64-year-old woman who presented with a 5-year history of motor and sensory disturbances in her right upper extremity...
