- Aim of the study: Presentation of diffusion tensor imaging (DTI) performed at low magnetic field (1 Tesla) in the algorithm of work-up of a patient suffering from severe traumatic brain injury (TBI).Method: DTI and functional MRI (fMRI) were applied at 1 Tesla for visualization of neural pathways and examination of sensory functions of a patient with severe TBI. DTI-measurement was also performed on a healthy patient for comparison.Results: DTI acquired at low magnetic field yielded appropriate visualization of neural pathways. DTI confirmed the results of the clinical and fMRI examinations in the patient suffering from severe TBI.Conclusion: An optimized DTI can be useful in the examination of patients with TBI, moreover, it may also help in the establishment of diagnoses of other central nervous system diseases affecting neuronal pathways. The presented results suggest that DTI of appropriate quality can be performed at low magnetic field.

- A case of a 61-year-old male patient suffered chronic renal failure and dialysed for 23 years with destructive cervical spondylarthropathy is presented. The patient presented with sudden onset of cervical pain radiating into his shoulders without neurological deficits. CT and MRI of the cervical and thoracic spine revealed severe destructive changes and compressive fractures of C6 and C7 vertebrae which caused the narrowing of the nerve root canals at these levels. A 360-degree fixation was performed to treat the unstable fracture and the patient's pain (C6 and C7 corpectomy, autolog bone graft replacement of the two vertebral bodies, anterior plate fixation and posterior instrumentation with screws and rods). Postoperatively the patient had no significant pain, no neurological deficit and he was able to manage independent life himself. During the immediate follow-up CT of the neck showed the satisfactory position of the bone graft and the metal implantations. The 6 months follow-up CT revealed the anterior migration of the two screws from the Th1 vertebral body and 2 mm ventral elevation of the caudal end of the plate from the anterior surface of the Th1 vertebral body. The 1-year follow-up could not be performed because the patient died due to cardio-pulmonary insufficiency. This is the second Hungarian report of a chronic dialysis related severe spondylarthropathy which may cause pathologic fractures of the vertebral bodies. The typical radiological and histological findings are discussed. This disease affect patients' quality of life and the conservative treatment alone seems to be ineffective in most cases. Based on the literature and personal experiences, the authors suggest 360-degree fixation of the spine to provide sufficient stability for the vertebrae of "bad bone quality", and early mobilisation of the patient can be achieved.

- Traumatic brain injury (TBI) is recognized to be the main cause of death and disability in the first four decades representing a major socio-economical problem worldwide. Recent communications revealed a particularly worrying image about the quality of care for TBI in Hungary. For any improvement a systematic approach characterized by utilization of scientific evidence based guidelines forming the basis for close monitoring of the actual care are considered a prerequisite. In Hungary the first evidence based guidelines in the field of TBI have been issued by the National Society for Anesthesiology and Intensive Care more than two decades ago followed by joint guidelines of the Hungarian Neurosurgical Society and the Hungarian College of Neurosurgeons. These publications were primarily based on the work of the European Brain Injury Consortium as well as guidelines issued by the Brain Trauma Foundation. Recent renewal of the latter and a need to refresh the outdated national guidelines was met by a call from regulatory authorities to issue the updated version of the Hungarian TBI-guidelines. The present review is aimed to briefly summarize the most fundamental elements of the national head injury guidelines that would hopefully be officially issued in a far more detailed format soon.

- Inclusion body myositis is the most common disabling inflammatory myopathy in the elderly. It is more frequent in men and after the age of 50 years. Inflammatory and degenerative features coexist. There is a T-cell mediated autoimmunity driven by in situ clonally expanded cytotoxic CD8-positive T-cells invading non-necrotic muscle fibres expressing MHC-I antigen. The hallmarks of degeneration are the deposition of protein aggregates and the formation of vesicles. The course of the disease is slow and the diagnosis is usually set after several years. The muscle weakness and wasting is assymetric, affecting predominantly distal muscles of the upper extremity and proximal muscles of the legs. The signs and clinical course can be characteristic, but the diagnosis is established by muscle biopsy. less thanbrgreater than less thanbrgreater thanThere is currently no evidence based effective treatment for sIBM. Prednisone, azathioprine, methotrexate, cyclosporine and IFN-beta failed. Oxandrolon did not improve symptoms. Treatment with intravenous immunglobuline (IVIG) induced in some patients a transient improvement of swallowing and of muscle strenght, but the overall study results were negative. less thanbrgreater than less thanbrgreater thanA T-cell depleting monoclonal antibody (alemtuzumab), in a small uncontrolled study slowed down disease progression for a six-month period. Repeated muscle biopsies showed the reduction of T-cells in the muscle and the suppression of some degeneration associated molecules. An effective therapeutic mean should act on both aspects of the pathomechanism, on the inflammatory and the degenerative processes as well.

- The combination of obstructive sleep apnea syndrome and vascular malformation within the head and neck region is a rare condition, and interestingly, only a few cases have recently been published. Propagation of the vascular mass to the larynx and pharynx can cause breathing and swallowing difficulties. Due to these sypmtoms, examination and initiation of appropriate therapy for such patients are indeed challenging. We reviewed the literature available and present our case of a 64 year old woman emphasizing the complaints of sleep apnea syndrome and vascular malformation of the face and neck region. Polygraphic examination detected severe obstructive sleep apnea syndrome. The MR examination of the neck revealed extensive vascular mass narrowing the pharyngo-laryngeal region, thereby causing temporal bone destruction on the right side with intracranial propagation. ENT examination demonstrated significant narrowing of the pharyngeal lumen and the laryngeal aditus caused by multiple hemangiomas. CPAP titration showed the minimalization of the apnea-hypopnea index on the effective pressure level. Regular CPAP usage resulted in diminishing a majority of the patient's complaints. Our examination clearly demonstrates, obstructive sleep apnea syndrome coupled with significantly obstructing vascular malformation in the head and neck region can be effectively treated safely with a CPAP device, if surgical therapy is not possible. We summarized our findings and the data available in the literature to set up recommendations for the appropriate examination and therapy (including mask fit, etc.) of vascular malformations and hemangiomas causing pharyngolaryngeal obstruction.

- Background and purpose: Deep brain stimulation (DBS) involves placing electrodes within specific deep brain nuclei. For movement disorders the most common indications are tremors, Parkinsons disease and dystonias. Surgeons mostly employ MR imaging for preoperative target selection. MR field geometrical distortion may contribute to target-selection error in the MR scan which can contribute to error in electrode placement.Methods: In this paper we compared the STN target planning coordinates in six parkinsonian DBS patients. Each patient underwent target planning in 1T and 3T MRI. We statistically compared and analysed the target-, and the fiducial coordinates in two different magnetic fileds.Results: The target coordinates showed no significant differences (Mann-Whitney test, p > 0.05), however we found significant difference in fiducial coordinates (p < 0.01), in 3T MRI it was more pronounced (mean ± SD: 0.8 ± 0.3 mm) comparing to 1T (mean ± SD: 0.4 ± 0.2 mm).Conclusion: Preliminary results showed no significant differences in planning of target coordinates comparing 1T to 3T magnetic fields.

- Background and purpose: The efficacy of intravenous thrombolysis (IVT) is moderate in the proximal vascular segments of intracranial arteries, as opposed to mecha-nical thrombectomy (MT). In the management of acute ischemic stroke (AIS) caused by large vessel occlusions (LVO), IVT prior to MT is highly recommended based on the latest guidelines, but the necessity of IVT has been questioned by the latest studies of the past years. The aim of our study was to investigate and compare the efficacy and safety of direct mechanical thrombectomy (dMT) and combined therapy (CT) for patients who suffered an AIS with LVO and were treated in our department.Methods: We investigated patients with AIS caused by LVO who were admitted up to 4.5 hours after symptom onset and underwent MT in our department between November 2017 and August 2019. Patients' data were collected in our stroke register. Patients enrolled in our study were divided into two groups depending on whether dMT or CT was used. Our primary outcome was the 30- and 90- day functional outcome measured by modified Rankin Scale (mRS). Mortality at 30- and 90- day, successful recanalization rates, and symptomatic intracranial hemorrhage were considered as secondary outcomes.Results: A total of 142 patients (age: 68.3 ± 12.6 years, 53.5% female) were enrolled in our study, including 81 (57.0%) dMT cases, and 61 (43.0%) patients who received CT. The vascular risk factors and comorbidities were significantly higher in the dMT-treated group. At day 30, the rate of favorable functional outcomes was 34.7% in dMT vs. 43.6% among those who received CT (p = 0.307), by day 90 this ratio changed to 40.8% vs. 46.3% (p = 0.542). Mortality rates at day 30 were 22.2% and 23.6% (p = 0.851), and at day 90 33.8% and 25.9% (p = 0.343). The rate of effective recanalization was 94.2% for dMT-treated patients and 98.0% for CT-treated patients (p = 0.318). Symptomatic intracranial hemorrhage was detected in 2.5% of dMT-treated patients and 3.4% of CT-treated group (p = 0.757).Conclusion: Our results suggest that CT is associated with a moderately better outcome compared to dMT. IVT prior to MT did not increase the risk of symptomatic intracranial hemorrhages.
