human infection with echinococcus granulosis is a common disease throughout south america, the mediterranean littoral, the middle east, central asia and east africa, which usually occur in children and young adults. formation of avascular cystic lesions in the liver, kidney, pancreas, bones, vitreus and brain can cause protean of signs and symptoms. intracranial cysts usually present with focal...

significant advances have been made in diagnosis and therapy of demyelinating disorders of the central nervous system. the most common entities of this disorders in adults – multiple sclerosis and neuromyelitis optica were initially thought to be different phenotypes of more or less the same disease. during the last ten years, this view was subsequently changed and the term neuromyelitis optica...

we describe a 40-year-old woman presenting with headache, nausea, episodic amnesia and blurred optic disc. brain mri disclosed diffuse leptomeningeal enhancement. csf analysis showed aseptic meningitis with elevated ace level. neurosarcoidosis was diagnosed based on granulomatosis changes on tissue biopsy.

background & objectives: the accurate assessment of the diseased tissue is fundamental to the diagnosis and management of disorders of the central nervous system (cns). the ‛squash’ or ‛crush’ technique has been universally employed in the intraoperative diagnosis of cns tumors. the aim of our study was to evaluate the accuracy of squash preparation in diagnosing cns tumors by comparing wit...

Network analyses in nervous system disorders involves constructing and analyzing anatomical and functional brain networks from neuroimaging data to describe and predict the clinical syndromes that result from neuropathology. A network view of neurological disease and clinical syndromes facilitates accurate quantitative characterizations and mathematical models of complex nervous system disorder...

Posttransplant lymphoproliferative disorders (PTLDs) represent a spectrum ranging from Epstein-Barr virus (EBV)-driven polyclonal lymphoid proliferations to EBV+ or EBV- malignant lymphomas. Central nervous system (CNS) PTLDs have not been characterized fully. We reviewed the clinical, radiologic, and pathologic features of 12 primary CNS PTLDs to define them more precisely. Patients included 1...

The autonomic nervous system is a crucial component in regulatory responses of the cardiovascular system. There has been increasing evidence of research demonstrating that dysregulation of this system has an important role in the pathogenesis of common cardiovascular disorders, including hypertension, heart failure, atrial fibrillation, cardiac sudden death or neurally-mediated syncope. This pa...

Purpose: Neurologic disorders may be seen in patients with cerebral malformations. The aim of this study is determining epilepsy and the other contributing disorders in the patients with cerebral malformations using Gross Motor Function Classification Scale (GMFCS) and Bimanual Fine Motor Function Scale (BFMFS) are used to determine motor function. Methods: The clinical and neuroradiologic feat...
