1/149. Subacute painful lumbosacral polyradiculoneuropathy in immunocompromised patients.The syndrome of inflammatory subacute lumbosacral polyradiculoneuropathy (SLP) has been reported in acquired immunodeficiency syndrome (AIDS) patients in association with cytomegalovirus infection and is only partially amenable to anti-viral therapy. We report three cases of relatively benign inflammatory painful SLP in two non-AIDS, immunosuppressed patients and one who hiv-seroconversed at the time of clinical presentation. SLP developed: (1) in association with hiv seroconversion; (2) during ECHO virus infection in a patient with common variable immune deficiency; and (3) after a severe systemic infection that induced transient immunosuppression due to Epstein-Barr virus reactivation. This report expands the spectrum of viruses associated with acute and subacute lumbosacral polyradiculoneuropathy and may shed light on its possible pathogenesis.- - - - - - - - - - ranking = 1keywords = polyradiculoneuropathy (Clic here for more details about this article) |
2/149. Chronic steadily progressive central and peripheral predominantly motor demyelination, involving the cranial nerves, responsive to immunoglobulins.The association of central and peripheral demyelination was reported previously. Most of the cases refer to central chronic relapsing demyelination with clinical criteria for multiple sclerosis associated with later signs of peripheral nerve involvement. Other authors, described central lesions in patients with chronic inflammatory demyelinating polyneuropathy and in guillain-barre syndrome, as a seldom occurrence. We report a patient in which a chronic steadily progressive central and peripheral predominantly motor nervous system demyelination, involving the cranial nerves, was identified. The patient improved after intravenous immunoglobulin suggesting an immune-mediated mechanism. To our knowledge this presentation was not described before.- - - - - - - - - - ranking = 0.47706538742691keywords = chronic inflammatory demyelinating, inflammatory demyelinating, demyelinating (Clic here for more details about this article) |
3/149. polyradiculoneuropathy revealing a solitary plasmacytoma of the ilium. A new case-report.Neurological manifestations are uncommon in myeloma patients, and subacute polyradiculoneuropathy as the inaugural manifestations of solitary plasmacytoma of bone is exceedingly rare. We report the case of a 52-year-old man who was evaluated for a three-month history of flaccid tetraplegia with a gradually ascending onset and for a deterioration in general health. electromyography findings were consistent with polyradiculoneuropathy. Laboratory tests showed a moderate amount of a monoclonal IgG-lambda antibody. Findings were normal from a radiographic bone survey and a radionuclide bone scan. Computed tomography of the pelvis disclosed a solitary osteolytic lesion in the right iliac crest, which was found upon biopsy to be a malignant plasmacytoma. radiation therapy and chemotherapy were given. Subacute or chronic polyradiculoneuropathy as the inaugural manifestation of solitary plasmacytoma is exceedingly rare and should be distinguished from the sensorimotor polyneuropathy produced by plasma cell infiltration in some multiple myeloma patients. The polyradiculoneuropathy of solitary plasmacytoma can be likened to the neuropathies seen in some forms of multiple myeloma (sclerotic myeloma and poems syndrome). The pathophysiology of these neuropathies remains obscure. The case reported here suggests that patients with unexplained lasting polyradiculoneuropathy should be investigated for a plasma cell proliferation even if they have no serum monoclonal component. Because plasmacytomas are painless, imaging studies are needed for their diagnosis. The management of the neuropathy consists in treatment of the tumor.- - - - - - - - - - ranking = 0.83333333333333keywords = polyradiculoneuropathy (Clic here for more details about this article) |
4/149. Spinal root and plexus hypertrophy in chronic inflammatory demyelinating polyneuropathy.MRI was performed on the spinal roots, brachial and lumbar plexuses of 14 patients with chronic inflammatory demyelinating polyneuropathy (CIDP). hypertrophy of cervical roots and brachial plexus was demonstrated in eight cases, six of whom also had hypertrophy of the lumbar plexus. Of 11 patients who received gadolinium, five of six cases with hypertrophy and one of five without hypertrophy demonstrated enhancement. All patients with hypertrophy had a relapsing-remitting course and a significantly longer disease duration. Gross onion-bulb formations were seen in a biopsy of nerve from the brachial plexus in one case with clinically evident nodular hypertrophy. We conclude that spinal root and plexus hypertrophy may be seen on MRI, particularly in cases of CIDP of long duration, and gadolinium enhancement may be present in active disease.- - - - - - - - - - ranking = 2.3853269371346keywords = chronic inflammatory demyelinating, inflammatory demyelinating, demyelinating (Clic here for more details about this article) |
5/149. Chronic inflammatory demyelinating polyneuropathy with multiple hypertrophic nerves in intracranial, and intra- and extra-spinal segments.Hypertrophic nerves have occasionally been seen in chronic inflammatory demyelinating polyneuropathy (CIDP), but most are in the cauda equina. We report a case with CIDP in whom magnetic resonance imaging (MRI) with gadolinium diethylene triamine penta-acetic acid (Gd-DTPA) enhancement demonstrated hypertrophy of various peripheral nerves including multiple cranial nerves. Interestingly, none showed neurological signs corresponding to the lesions, except for clinical signs consistent with CIDP. MRI can be useful for the detection of silent, but abnormal nerve involvement in CIDP.- - - - - - - - - - ranking = 1.204974499928keywords = chronic inflammatory demyelinating, inflammatory demyelinating, demyelinating (Clic here for more details about this article) |
6/149. Congenital muscular dystrophy with central and peripheral nervous system involvement in a Belgian patient.We report a patient with congenital muscular dystrophy (CMD), developmental brain defects, and peripheral neuropathy. Marked hypotonia and plagiocephaly were noted at birth. failure to thrive, generalized muscle weakness and wasting, absent deep tendon reflexes, partial seizures, and secondary microcephaly developed. brain MRI showed a large area of cortical dysplasia, a thin but complete corpus callosum, and diffuse ventriculomegaly. Nerve conduction velocities were slow and creatine kinase levels only mildly elevated. Muscle biopsy showed dystrophic features with normal merosin, sarcoglycan, and dystrophin immunostaining. The Japanese Fukuyama CMD founder mutation was not detected. This is the first report of a patient with merosin-positive CMD, cobblestone lissencephaly, and demyelinating peripheral neuropathy.- - - - - - - - - - ranking = 0.044150028365098keywords = demyelinating (Clic here for more details about this article) |
7/149. Clinicopathological study of an autopsy case with sensory-dominant polyradiculoneuropathy with antiganglioside antibodies.A previously reported patient presenting sensory-dominant neuropathy with antiganglioside antibodies, bound preferentially to polysialogangliosides including GD1b, was autopsied. While axonal degeneration was predominant in the sural nerve, many demyelinated fibers were present in the spinal roots. Dorsal roots had undergone significant damage. These pathological findings were well correlated with the electrophysiological results showing decreased F-wave conduction velocities and conduction blocks in motor nerves and decreased or absent sensory action potentials in sensory nerves, with distribution of GD1b in nerve tissues such as dorsal root ganglia and paranodal myelin in the ventral and dorsal roots.- - - - - - - - - - ranking = 0.66666666666667keywords = polyradiculoneuropathy (Clic here for more details about this article) |

9/149. Three different anti-myelin antibodies in a case of demyelinating dysglobulinemic peripheral neuropathy.We report the case of a patient with a severe, predominantly motor, demyelinating neuropathy associated with an IgM kappa biclonal gammopathy. Immunoblot studies showed IgM reactivity against MAG, and IgG reactivity against a peripheral nerve myelin-specific protein of approximately 35 kDa. Immunodetection by thin layer chromatography showed IgM reactivity towards GM1 and GD1b, as well as towards SGPG and SGLPG. This case illustrates the existence of overlapping syndromes among dysglobulinemic neuropathies, and points to an interaction of different autoantibodies in the pathogenesis of the nerve lesions.- - - - - - - - - - ranking = 0.22075014182549keywords = demyelinating (Clic here for more details about this article) |
10/149. Hypertrophic perineurial dysplasia in multifocal and generalized peripheral neuropathies.Two cases are described, one with a multifocal cranial and limb neuropathy of adult onset associated with optic neuropathy, and the other with a diffuse demyelinating neuropathy characterized by congenital cataract, mental retardation and progressive lower limb paresis with an onset in childhood. Extensive investigation in both failed to establish the causation. No family history of similar disorder was obtained in either case. Nerve biopsy in both showed similar perineurial abnormalities, the endoneurium being compartmentalized by hypertrophic perineurial cells that exhibited dysplastic features. The appearances resemble those described in a previously reported case of multifocal neuropathy and probably represent an unusual but non-specific response to a peripheral neuropathy.- - - - - - - - - - ranking = 0.044150028365098keywords = demyelinating (Clic here for more details about this article) |
