Evolution of acute "black hole" lesions in patients with relapsing-remitting multiple sclerosis.

Objective: Gadolinium-enhanced T1-weighted lesions are a well-established marker of areas with acute inflammatory activity. A majority of these gadolinium-enhanced T1 lesions are isointense relative to the surrounding white matter, but 20-40% of such active lesions will evolve during one year into areas of low signal ("black hole"). This study sought to characterize evolution of "black hole" lesions in patients with relapsing-remitting multiple sclerosis (MS) using the magnetic resonance imaging (MRI), which measures active lesions via the count of new or enlarged T2 and gadolinium-enhanced T1-weighted lesions.

L-2-Hydroxyglutaric aciduria: a case report.

Introduction: L-2-Hydroxyglutaric aciduria (L-2-HGA) is an autosomal recessive neurometabolic disease with a slowly progressive course and characterized by increased levels of hydroxyglutaric acid in urine, cerebrospinal fluid and plasma. In this condition clinical features mainly consist of mental deterioration, ataxia and motor deficits.

Case Outline: The patient is a 16-year-old girl, the first and only child of healthy, non-consanguineous parents of Serbian origin.

The functional neuroimaging evidence of cerebellar involvement in the simple cognitive task.

Cerebellar involvement in cognitive functions has been revealed in numerous anatomical, clinical and neuroimaging studies and several hypotheses about potential the role of the cerebellum in higher level brain function have been established. The aim of this study was to show involvement of the cerebellum in simple cognitive tasks. For this matter, we contrasted two tasks from the same semantic domain with specific cognitive content and level of practice: counting forward and counting backward.

[Ultrasonography and magnetic resonance imaging in prenatal diagnosis of tumour of the foetal head and neck].

Introduction: Foetal tumours are relatively rare; prenatal diagnosis enables additional diagnostics, and thus the decision on the continuation of pregnancy and planning of delivery. The paper presents prenatal ultrasound diagnostics of foetal head tumour with additionally analyzed magnetic resonance imaging (MRI).

Case Outline: On ultrasound imaging, in a 27-year-old nullipara, a tumour of the foetal head was suspected at the 22nd gestational week.

Partial rhombencephalosynapsis: prenatal MR imaging diagnosis and postnatal follow up.

We present a case of partial rhombencephalosynapsis, diagnosed by magnetic resonance imaging (MRI), in fetus aged 27 gestational weeks, in a dizygotic twin pregnancy. The distinctive MRI features of this cerebellar malformation (segmental hypogenesis of the cerebellar vermis, partial fusion of the cerebellar hemispheres and dentate nuclei) without associated cerebral abnormalities were confirmed by 32-weeks prenatal and 3-months postnatal MRI studies. At the age of 12 months the affected twin had a slight delay in psychomotor development, mild hypotonia with normal cognitive development.

[Functional magnetic resonance imaging of cortical changes in a low-grade glioma patient].

Introduction: New methods for studying brain functions have provided the new insights into human brain. It is really possible to study a cortical adaptation in adults who have sustained injury. We reported cortical changes in a left frontal low-grade glioma patient during disease progression and after reoperation by functional magnetic resonance imaging (fMRI).

Gender differences in brain areas involved in silent counting by means of fMRI.

Background: Pattern of brain asymmetries varies with handedness, gender, age, and with variety of genetic and social factors. Large-scale neuroimaging analyses can optimize the detection of asymmetric features and confirm the factors that might modulate pattern of brain asymmetries. We attempted to evaluate eventual differences between genders in hemodynamic responses to a simple language task.

Intrauterine treatment of large fetal neck lymphangioma with OK-432.

Lymphangiomas are benign vascular malformations of the lymphatic system and most commonly present in the neck area. Large lymphangiomas may compress and/or displace the larynx, trachea and esophagus and cause serious respiratory and feeding problems in neonates. Prenatal therapy could eliminate the risks of the mentioned complications.

Prenatal diagnosis of posterior fossa anomalies--an overview.

Ultrasonography of the central nervous system is an integral part of a prenatal scan, and the development of imaging technologies has led to better diagnostic possibilities. Posterior fossa anomalies have traditionally been divided into Dandy Walke malformation, Dandy Walker variation and megacisterna magna, but this approach, due to diversity of the extensive number of possible disorders covered by this classification, unables accurate prognosis and therefore adequate counselling. An alternative approach to the classification of posterior fossa anomalies is to divide them into agenesis of the vermis, which could be partial or complete, cerebellar hypoplasia, pontocerebellar hypoplasia and cerebellar atrophy.

[Current diagnostic trends in radiology].

Since the discovery of X-rays by Wilhelm Conrad Röentgen at the end of the 19th century, diagnostic imaging techniques have been continously improved by technological advances, bringing radiological diagnosis into the very center of modern medicine. Nowadays, it is hard to imagine therapy planning without previous radiological examination. Great advances in the field of computer technology have been accompanied by development of radiological techniques, and today they include not only morphological and anatomical, but also dynamic, functional and molecular imaging.
