Cryptococcus neoformans is a yeast that most commonly infects the central nervous system. Meningitis and meningoencephalitis are the most common presentations of cryptococcosis. Cryptococcoma, however, is a rare entity characterized by localized, solid, tumor-like masses that are usually found in the cerebral hemispheres or cerebellum, but are extremely(More)
Multiple sclerosis is a chronic inflammatory demyelinating disease of the central nervous system. Diffusion tensor magnetic resonance imaging (DTI) can yield important information on the in vivo pathological processes affecting water diffusion. The aim of this study was to quantitatively define water diffusion in normal-appearing white matter (NAWM) distant(More)
Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system, predominantly affecting the white matter, but also the grey matter. Aim of this study was to detect MS lesions with double inversion recovery (DIR), fluid-attenuated inversion recovery (FLAIR) and T2-weighted magnetic resonance (MR) techniques and determine the(More)
OBJECTIVE In this report, we aimed to investigate the patients that presented at our clinic complaint with diplopia due to the abducens nerve palsy and neurosurgical disease. METHODS The study design was a retrospective review of ten cases with the abducens nerve palsy. The causes of the abducens nerve paralysis of our patients were as follows: two cases(More)
INTRODUCTION The limbic system primarily responsible for our emotional life and memories is known to undergo degradation with aging and diffusion tensor imaging (DTI) is capable of revealing the white matter integrity. The aim of this study is to investigate age-related changes of quantitative diffusivity parameters and fiber characteristics on limbic(More)
ABSTRACT Two female patients, aged 23 and 25 years-old diagnosed with Familial Mediterranean fever (FMF) were presented with ataxia and headache. Multiple sclerosis plaques were detected in their spinal and cranial MRI and diagnosis of multiple sclerosis was established. Genetic analysis demonstrated M694 V mutation (one homozygous and the other(More)
This study investigated diffusion abnormalities in the parts of corpus callosum (CC) of patients with Alzheimer's disease (AD) using diffusion tensor magnetic resonance imaging (DT-MRI). Twenty-one patients with AD and 20 healthy volunteers participated in the study. MRI was performed with a 1.5 T system. Conventional MR images and diffusion tensor images(More)
INTRODUCTION Arterial stiffness (AS) is a well-accepted and reliable predictor of atherosclerotic diseases. Inflammation plays an important role in the development of AS. AIM To evaluate local carotid stiffness (CS) together with fibrinogen and high-sensitivity C-reactive protein (hsCRP) levels in stable angina pectoris (SAP) patients. MATERIAL AND(More)
Epilepsy is more than a grey-matter disorder affecting large white matter connections of the brain with seizure generation and propagation. The mechanism for such changes remains unclear. The purpose of this study was to investigate the microstructural changes in the corpus callosum in temporal lobe epilepsy (TLE) patients and whether these abnormalities(More)
AIM Cardiovascular (CV) disease is the reason for most mortality cases in RA and cannot be explained only by the presence of traditional CV risk factors. In this study, we aimed to investigate the relationship between local carotid stiffness (CS) parameters measured by a novel ultrasound method and inflammatory disease activity in rheumatoid arthritis (RA)(More)
