OBJECTIVE Detection of nerve enlargement in polyneuropathies by sonography is a new research area. No systematic investigation has been done yet in chronic inflammatory demyelinating polyneuropathy (CIDP). Therefore we investigated this in CIDP. METHODS Eleven patients with CIDP fulfilling the international criteria on CIDP underwent ultrasonographic(More)
Clinical, laboratory and electrodiagnostic studies are the mainstay in the diagnosis of polyneuropathy. An accurate etiological diagnosis is of paramount importance to provide the appropriate treatment, prognosis and genetic counselling. High resolution sonography of the peripheral nervous system allows nerves to be readily visualized and to assess their(More)
Aneurysms of the intracranial arteries in the pediatric population are reportedly rare. There is a male predominance, association with connective tissue disorders, as well as bacterial, mycotic infections, and trauma. Common sites of presentation are the internal carotid artery bifurcation, posterior circulation, and distal segment of middle cerebral(More)
To study disease mechanisms in multifocal motor neuropathy (MMN) with magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) of the median and ulnar nerves. We enrolled ten MMN patients, ten patients with amyotrophic lateral sclerosis (ALS) and ten healthy controls (HCs). Patients underwent MRI (in a prone position) and nerve conduction(More)
BACKGROUND AND PURPOSE To compare the performance of neuroimaging techniques, i.e. high-resolution ultrasound (HRUS) and magnetic resonance imaging (MRI), when applied to the brachial plexus, as part of the diagnostic work-up of chronic inflammatory demyelinating neuropathy (CIDP) and multifocal motor neuropathy (MMN). METHODS Fifty-one incident,(More)
INTRODUCTION Differentiating multifocal motor neuropathy (MMN) from amyotrophic lateral sclerosis (ALS) is important, as MMN is a difficult, but treatable disorder. METHODS We studied peripheral nerve imaging techniques in differentiating MMN from ALS by measuring the cross-sectional area (CSA) of the median and ulnar nerves in the forearms using high(More)
OBJECTIVE To determine the diagnostic value of high-resolution ultrasound (HRUS) for detection of chronic inflammatory demyelinating polyneuropathy (CIDP), Lewis-Sumner syndrome (LSS), and multifocal motor neuropathy (MMN). METHODS Between January 2013 and January 2015, we enrolled 75 consecutive treatment-naive patients with chronic inflammatory(More)
The research field of high-resolution sonography (HRUS) of peripheral nerves is rapidly expanding. Traditionally, clinical assessment of patients starts with obtaining the history, clinical examination and is followed by electrodiagnostic testing. Nowadays, in addition to traditional examination of nerve function, HRUS is applied to assess the morphology of(More)
