[We present the case of a 7 years old boy with the juvenile form of metachromatic leukodystrophy. Beside conventional sequences, a diffusion-weighted magnetic resonance study was performed. On T2-weighted images a diffuse hyperintensity of the cerebral white matter with a typical tigroid pattern was seen as a well-known characteristics of the disease. No difference was detectable on T2-weighted images between the different cerebral white matter regions. Diffusion study showed low apparent diffusion coefficient values in the temporal and orbitofrontal regions and normal values in other cerebral regions compared to the normal appearing cerebellar white matter, wich is partly consistent with the previously reported data. The results of early diffusion studies of the disease are not straightforward and the physical and biochemical backgrounds of the diffusion properties still remain unknown. The more data we collect, the closer we get to the understaning of the diffusion changes in metachromatic leukodystrophy.]

[Current issues of neuroimaging diagnostics of multiple sclerosis]

BAJZIK Gábor

[Magnetic resonance imaging techniques have been routinely used in diagnostics and follow-up of multiple sclerosis and magnetic resonance imaging findings are incorporated into the current diagnostic criteria of the disease. International guidelines were created aiming to define the indication, timing, minimum requirements and interpretation of magnetic resonance examination in multiple sclerosis. In Hungary, there is a lack of widely-accepted standardized protocol, therefore presenting the magnetic resonance diagnostic criteria and the international guidelines may prove useful. It may also point towards consideration of a national guideline.]

[State of the art neurointerventional treatment of intracranial vascular anomalies]

SZIKORA István, BERENTEI Zsolt, MAROSFŐI Miklós, KULCSÁR Zsolt, GUBUCZ István

[Haemorrhagic stroke is frequently caused by rupture of intracranial vascular anomalies. The role of minimally invasive therapy in the treatment of such lesions has increased dramatically within the past two decades. The purpose of this study is to summarize the pathology and clinical features of these anomalies and to overview the potential applications of neurointerventional techniques in their treatment. Endovascular therapy is the first choice of treatment for most intracranial aneurysms. Both pial and dural arteriovenous malformations are being treated by endovascular techniques, but the combination of different modalities (such as endovascular, direct surgery and radiosurgery) is frequently applied. Capillary malformations require surgical removal and venous anomalies do not allow for any type of invasive treatment. State of the art therapy of intracranial vascular anomalies require institutions equipped with appropriate imaging facilities and having equal access to both conventional neurosurgical and neurointerventional techniques with ample experience and case load.]

[Plasticity of brain lateralization in epilepsy: fMRI studies]

KALMÁR Zsuzsanna, WOERMANN Friedrich, SCHWARCZ Attila, JANSZKY József

[Aims - This review is a summary of four studies investigating the effect of epileptic disturbance and other functional factors on the brain lateralization. Methods - Patients were investigated by functional MRI by using visual, sensorimotor, memory, and speech paradigms. Results - 1. Malformations of cortical development localized within speech centers induce contralateral speech reorganization in only 50% of cases. 2. Epileptic disturbance can induce a reorganization in language lateralization independent of the effect of lesion. 3. Bilateral epileptic activity can prevent a reorganization of memory functions contralateral to the seizure onset region. 4. Injury of the right upper limb can induce a left-to-right shift of language lateralization. Conclusions - Our results may have implication during neurorehabilitation process and neurosurgical interventions. Participation of malformations of cortical development in cognitive functions should keep in mind during surgery. Reorganization of speech- and memory functions should also be considered during operations of central nervous system.]

[Deep brain stimulation is a widely used technique for the treatment of movement disorders. This method is a breakthrough in treatment of drug-resistant idiopathic Parkinson’s disease, essential tremor and dystonia. The aim of the present paper is to give an inside overview of the postoperative management like fine tuning of the stimulation and balancing the antiparkinsonian medication. We also discuss the advantage of the use of the (Access Therapy) patient controller. After reviewing the stimulation-related side-effects and their management, the contraindicated medical procedures are discussed.]

[Childhood sporadic type of hemiplegic migraine with arteria cerebri media hypoperfusion]

NAGY Csaba, BAJZIK Gábor, SKOBRÁK Andrea, CSORBA Eszter, LAJTAI Anikó, BALOGH Gábor, NAGY Ferenc, VAJDA Zsolt

[Hemiplegic migraine is a rare subtype of migraine that is associated with reversible motor weakness in the aura phase. This is an uncommon form of migraine usually starting in childhood. The purpose of this case report is to highlight the differential diagnostic difficulty of the first attack. We describe a case, where the fluctuating unilateral motor weakness and aphasia suggested that the patient had ischaemic stroke. Nevertheless the brain MRI and MR angiography, the measured 5-hydroxyindole acetic acid (5-HIAA) concentration changes and the spontaneously improving clinical status proved the diagnosis of hemiplegic migraine. The MRI and MR angiography was very beneficial in establishing the correct diagnosis in this case. To distinguish between the familiar and sporadic type of hemiplegic migraine further genetic tests can be carried out.]

[Infective sacroiliitis]

BARTHA Attila

[INTRODUCTION - Pyogen infection of the sacroiliac joint occurs rarely in rheumatological practice. Its clinical symptoms are diverse, so the diagnosis is often made late. CASE REPORT - The author presents a case of a 67-year-old woman. The patient did not have any major diseases nor any predisposing factors for infection. Five days after doing hard physical work she felt strong pain irradiating from her lower back to the right lower limb. She was referred to the Department of Neurology with the diagnosis of right lumbar radiculopathy. She was primarily examined for tumours because of her high red blood cell sedimentation rate and CRP level and her inability to walk. The correct diagnosis was set up on the basis of MRI examination: infective sacroiliitis on the right side, which has spreaded to the adjacent tissues. USguided biopsy was unsuccesful, so empiric antibioitic treatment was started. The patient was discharged from hopsital after 35 days and continued clindamycin therapy at home. At control examination 6 month later she did not have any symptoms or complaints and laboratory examinations did not indicate inflammatory activity. MRI examination still showed an extensive oedema. CONCLUSION - Pyogen arthritis should be considered even in the absence of fever, leukocytosis and predisposing factors. By making the correct diagnosis and starting long-term antibiotic therapy in time, joint destruction is preventable and the patient is curable.]

[We previously reported a male patient with an 18q21.3 deletion, hyperuricemia and typical symptoms of the Lesch- Nyhan syndrome who lacked hypoxanthine-guanine-phosphoribosyl- transferase (HGPRT) deficiency. The patient developed progressive peripheral neuropathy in additon to his profound mental retardation and self-injurious behavior. At the age of 23 years MR imaging revealed globally delayed myelination with relative sparing of the corpus callosum and frontal lobes. They were focal hyperintensities suggestive of gliosis. Multimodality evoked potentials found evidence of impaired central and peripheral conduction. Single photon emission computed tomographic (SPECT) imaging demonstrated left frontal hyperperfusion and under it a temporoparietal hypoperfusion.]

[Comparison of different gastrointestinal contrast materials for MR examination, an experimental model]

BABOS Magor, PALKÓ András, KARDOS Lilla, CSERNAY László

[PURPOSE - Evaluation of different gastrointestinal endoluminal contrast materials by using an experimental model. MATERIALS AND METHODS - Authors constructed a plastic container holding six plastic cups, thus making possible to evaluate different compounds and concentrations, simultaneously. The signal intensity of more than 15 different materials (commonly used contrast materials, fruit juices, cocoa, iron containing solutions) was measured by T1 and T2 weighted spin echo sequences in a 1T MR unit. The results were compared in tables and demonstrated by figures. RESULTS - The plastic container and cups made it possible to evaluate the contrast materials by MR examination. The fruit juices containing metallic components had high signal intensity on T1 weighted images, while on the T2 weighted images showed moderate to high signal intensity except the rosehip syrup and a special blackcurrant extract, which were of low signal intensity. Cocoa drink had low to moderate signal intensity on both the T1 and T2 weighted images. The signal intensity of the iron(III)-desferrioxamin solution increased on the T1 weighted images and decreased on the T2 weighted images in direct proportion to its iron concentration. CONCLUSION - The described in vitro model is an appropriate and risk-free solution for selecting the proper endoluminal contrast material, its concentration, and the best measuring sequences for defining the optimal in vivo MR bowel examination protocol. On the base of the experimental results rosehip syrup, blackcurrant extract, iron(III)- desferrioxamin and cocoa drink were selected for further in vitro and in vivo examinations.]
