BACKGROUND Critical illness polyneuropathy (CIP) is a complex disease affecting 30-70% of critically ill patients. METHODS Clinical (Barthel index, length of stay (LOS), morbidity, duration of mechanical ventilation, routine lab results) and neurophysiological (neurography) data of 191 patients admitted to neurological early rehabilitation and diagnosed with CIP have been analyzed retrospecti...

An 8-year-old girl presented with progressive painless right peroneal and tibial nerve palsy. A 20-year-old woman had insidious weakness of the left wrist and fingers extension. Both underwent neurophysiology (tables e-1 through e-4 on the Neurology® Web site at Neurology.org) and nerve ultrasound that showed enlargement of sciatic (figure, A) and radial nerve (figure, D–E). A 3D–magnetic reson...

The advent of magnetic resonance imaging (MRI) allowed a significant advance in the understanding and evaluation of the central nervous system. However, the peripheral nervous system (PNS)—nerves, ganglia, and roots—continued to be considered “difficult to assess” by radiologists(1). The PNS has been studied through invasive tests, such as electrodiagnostic studies and nerve biopsies, which cau...

Background Charcot-Marie-Tooth (CMT) disease is clinically and genetically heterogeneous. There are no published series describing clinical, electrophysiological, and genetic information on CMT from the Indian subcontinent. Magnetic resonance imaging (MRI) neurography technique provides useful information about the plexus and roots and can be employed in patients with CMT. Settings and Design...

The authors report an unusual case of ulnar neuropathy caused by granular cell tumor. The report describes the anatomic 3 Tesla MR Neurography and functional diffusion tensor findings of the case, which was subsequently confirmed on surgical excision and histopathology.

High-resolution magnetic resonance (MR) Neurography is a novel imaging technique, which enables multiplanar imaging of peripheral nerves, as well as diagnosis and localization of entrapment and non-entrapment peripheral neuropathies related to etiologies, such as inflammation, tumor and trauma. Typically, MR Neurography techniques utilize a combination of fat-saturated T2-weighted, short invers...

A 46-year-old man with a history of recurrent facial nerve palsies, right trigeminal neuralgia, and Horner syndrome presented with subacute onset of right laryngeal hemiparesis. CSF analysis revealed normal cell count and elevated protein level with albumin-cytologic dissociation. Imaging workup ruled out compressive and infiltrative causes. Magnetic resonance neurography (figures 1A and 2, A–D...

MR imaging of peripheral nerves not only allows sensitive detection of peripheral nerve abnormalities but also displays high detail of regional anatomy and improves specificity of diagnosis. The use of MR imaging for diagnosis and evaluation of peripheral nervous system disorders was initially reported in the late 1980’s. Since then, expertise gained through experience over the last decade coup...
