A 50-year-old woman reported several years of progressive lower back pain in the supine position. Results of the neurologic examination were normal. MRI of the lumbar spine was performed (figure). After surgery, which revealed an intraspinal intradural schwannoma, the patient had no neurologic complaints. Schwannoma of the cauda equina usually develops at the L1–L2 level and causes back pain, s...

A 43-year-old man presented for neurologic evaluation with acute bilateral hearing loss. Two weeks before presentation, he had bilateral eye pain diagnosed as scleritis. He also noted a subacute history of fevers, night sweats, and diarrhea. Neurologic examination revealed bilateral sensorineural hearing loss, confirmed with audiometry. MRI demonstrated enhancement of the cochlea bilaterally (f...

A 28-year-old woman presented with slowly progressive ataxia and signs of upper and lower motor neuron dysfunction. She had no family history of neurologic disease. Neuroimaging study results were unremarkable, and the diagnosis remained obscure for several years. The differential diagnosis of motor system degeneration in a young adult is broad but focuses on inherited disorders that may have l...

Linear scleroderma represents a unique form of localized scleroderma that primarily affects the pediatric population, with 67% of patients diagnosed before 18 years of age. When linear scleroderma occurs on the head, it is referred to as linear scleroderma en coup de sabre, given the resemblance of the skin lesions to the stroke of a sabre. Here we describe 3 pediatric patients with linear scle...

Spinal injuries and associated neurologic dysfunction are encountered frequently in small animal practice. Such injuries are most often the result of automobile trauma, or less commonly gunshot injuries, falls from heights, or animal abuse. The vertebral column has two distinct functions that become compromised in the injured animal and that must be considered in the diagnosis and management of...

Paget's disease in the Far East is quite rare. Age at diagnosis is usually greater than 50 years, and the disease typically affects the spine. Most patients are usually diagnosed with Paget's disease following radiographic examination for other purposes. It usually occurs at multiple vertebral levels, with only 10-25% of vertebral Paget's disease being monostotic. The disease rarely causes neur...

Traumatic atlanto-occipital dislocation is an uncommon injury that frequently results in either a fatal outcome or severe neurologic deficit. This diagnosis must be considered for any patients who may have had cervical spine damage after high trauma, even in the absence of neurologic signs, as there have been reports of cases without neurologic impairment. In addition to radiographic examinatio...

Spontaneous cervical epidural hematoma (SCEDH) is a rare disease, but can cause severe neurologic impairment. We report a case of a 68-year-old female who presented with sudden onset, posterior neck pain, right shoulder pain, and progressive right hemiparesis mimicking stroke with no trauma history. Initial brain CT and diffusion MRI performed to rule out brain lesion did not show any positive ...

Outbreaks of West Nile (WN) virus occurred in the New York metropolitan area in 1999 and 2000. Nineteen patients diagnosed with WN infection were hospitalized in New York and New Jersey in 2000 and were included in this review. Eleven patients had encephalitis or meningoencephalitis, and eight had meningitis alone. Ages of patients ranged from 36 to 87 years (median 63 years). Fever and neurolo...

mirror movement is an interesting but often overlooked neurological soft sign;these movements are described as simultaneous contralateral, involuntary, identical movements that accompany voluntary movements. this neurologic problem is very rarely seen in children; in familial cases there is a positive history of these movements in parents, diminishing with time. here, we have presented the case...
