BACKGROUND Neuromyelitis optica (NMO) is the first inflammatory autoimmune demyelinating disease of the central nervous system for which a specific antigenic target has been identified; the marker autoantibody NMO-IgG specifically recognizes the astrocytic water channel aquaporin 4. Current evidence strongly suggests that NMO-IgG may be pathogenic. Since(More)

OBJECTIVE To report the clinical phenotype and outcome of isolated paraneoplastic myelopathy. METHODS We systematically reviewed clinical, serologic, and MRI data for 31 patients (20 female) who presented with an isolated myelopathy and coexisting cancer: carcinoma (lung, 9; breast, 7; kidney, 2; thyroid, 2; ovary/endometrium, 2), melanoma (2), or other(More)
BACKGROUND Plasma exchange (PLEX) is a beneficial rescue therapy for acute, steroid-refractory central nervous system inflammatory demyelinating disease (CNS-IDD). Despite the approximately 45% PLEX response rate reported among patients with CNS-IDD, determinants of interindividual differences in PLEX response are not well characterized. OBJECTIVE To(More)
BACKGROUND Leukoencephalopathy with neuroaxonal spheroids is a rare cause of severe, subacute dementia that usually presents in childhood and is inherited in an autosomal dominant pattern. The authors present clinical, radiologic, and pathologic features of adult-onset, sporadic cases mimicking cerebral-type progressive MS. METHODS Five patients referred(More)
OBJECTIVE Among the rare causes of myelopathies is primary intramedullary spinal cord lymphoma (PISCL). As PISCL is often underrecognized, delaying appropriate treatment, we sought to describe its presentation, imaging characteristics, and outcomes. METHODS Mayo Clinic medical records, lymphoma database, and autopsies from 1996 to 2009 were searched.(More)
Pharmacotherapeutic options for multiple sclerosis (MS)-related fatigue are limited. Thirty patients were randomly assigned to aspirin (ASA) 1,300 mg/day or placebo in a double-blind crossover study. Results favored ASA for the main clinical outcomes: Modified Fatigue Impact Scale scores (p = 0.043) and treatment preference (p = 0.012). There were no(More)
Reported are three children with MS who responded dramatically to interferon-beta (IFNbeta) therapy. While on immunomodulatory therapy, they developed chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) that responded to IV immunoglobulin (IVIG) administration. These cases emphasize two interesting observations: 1) IFNbeta treatment did not(More)
BACKGROUND Opsoclonus-myoclonus syndrome and breast carcinoma were initially described as neurologic and oncologic accompaniments of antineuronal nuclear autoantibody type 2 (ANNA-2, also known as anti-Ri). However, the neurologic spectrum of ANNA-2 autoimmunity is broader, includes a syndrome of jaw dystonia and laryngospasm, and can be accompanied by lung(More)
Leucodystrophy with neuroaxonal spheroids (LNS) is rare. There have been fewer than 10 sporadic cases reported, all occurring in the fourth to sixth decades of life. Previously unreported diffusion weighted imaging (DWI) changes on brain imaging in LNS are described as well as the first neurocognitive profile of this disorder in a 24-year-old woman.(More)
Intramedullary spinal cord metastases of solid neoplasms are associated with poor long-term survival. As the characteristics of secondary intramedullary spinal cord non-Hodgkin’s lymphoma (NHL) are not well understood, we sought to describe its clinical features and outcome. We retrospectively reviewed the Mayo Clinic patient database, lymphoma database,(More)
