Abstract The clinical symptoms and MRI characteristics of transverse myelopathy (TM) due to non-compressive causes are reviewed, with special emphasis on the differential diagnosis between ...inflammatory demyelinating lesions, and metabolic and vascular myelopathies. Inflammatory transverse myelopathies are the commonest and most difficult ones to identify. The differentiation between clinically isolated syndromes, multiple sclerosis, neuromyelitis optica, acute disseminated encephalomyelitis and metabolic causes is based on both clinical symptoms and paraclinical signs including magnetic resonance imaging, cerebrospinal fluid analysis, and immunological and biochemical parameters. The most intriguing form of TM is that where there is clinical evidence of complete spinal cord transection, with normal findings in magnetic resonance imaging in the acute phase, but subsequent cord atrophy.
Complex regional pain syndrome type I (CRPS I) is a disorder of one or more extremities characterized by pain, abnormal sensitivity (allodynia), swelling, limited range of motion, vasomotor ...instability, fatigue and emotional distress. The symptoms may be aggravated by even minor activity or weather change. It is usually provoked by injury, surgery or injection but in a small proportion of patients CRPS I develops without a clear causative event. There are several literature reports on CRPS after rubella and hepatitis B vaccination. We present a case of CRPS I affecting the left arm after diphtheria and tetanus (Di-Te) vaccination in the left deltoid muscle in a young girl having experienced profound emotional stress before the vaccination procedure. History data on previous minor trauma at the site of vaccination or emotional stress may necessitate temporary vaccination delay due to their proneness to impaired local or systemic immune response and CRPS as a complication of vaccination. If a child or an adult has prominent swelling and severe pain after vaccination, the diagnosis of CRPS I should be considered and if confirmed, the multidisciplinary treatment should start as soon as possible.

Autoimmune diseases represent a diverse group of disorders that have generally of unknown etiology and poorly understood pathogenesis. They may be organ-specific or systemic, giving rise to ...overlapping syndromes; more than one autoimmune disease may occur in the same patient. Numerous case reports have documented that multiple sclerosis (MS) may be present concurrently with other autoimmune diseases, most commonly rheumatoid arthritis, autoimmune thyroid disease, type I diabetes mellitus and pernicious anemia. Case reports of disseminated encephalomyelitis (DEM) coincidental with other autoimmune diseases are rare. Many of systemic autoimmune diseases cause central nervous system (CNS) demyelination and are frequently then diagnosed as MS, whereas they often are instances of DEM, the result of vascular, granulomatous or postinfectious manifestations. We have reviewed 15 patients with autoimmune diseases and CNS demyelination in order to determine the nature of the demyelinating process.
Spinal arteriovenous malformations (AVM) have been devided into dural (Type I), intramedullary glomus (Type II), juvenile (Type III), and perimedullary direct arteriovenous fistulae (Type IV). AVMs ...are usually associated with subacute myelopathy in what has been known as Foix-Alajouanine syndrome. We presented two patients with two intradural spinal arteriovenous malformations associated in what we call Foix-Alajouanine syndrome. The both patient developed acute back pain and paresthesias, followed by paraplegia and incontinence. The clinical status of one patient has been improved after particle embolization for a 17 years when he deteriorated up to paraplegia after spinal angiography for follow up. Clinical status in another patient deteriorated, because particle emoblisation cannot be performed due to very descrete presentation of the feeding artery. Extensive neuroradiological examination in both patients revealed coexistence of numerous associated developmental anomalies in both patients. We conclude that arteriovenous malformations occasionally are associated with other vascular and nonvascular developmental anomalies elsewhere in the body. These findings rise attention about keep in mind the suspicion of mutual etiopathogenesis and congenital origin of these anomalies. Early timing of the diagnostic and therapeutic interventiosn are stressed to prevent or delay irreversible ishaemic myellopathy or haemorrhage. For the definitive diagnosis of spinal arteriovenous malformations and evaluation of its occlusion grade after the therapy spinal angiography is needed
In myasthenia gravis (MG) patients without detectable anti-acetylcholine receptor (anti-AChR) antibody, referred to as seronegative myasthenia gravis patients, there is a variable proportion of ...patients with antibodies against the muscle-specific kinase (MuSK). MuSK antibodies were found in 8 (29.6%) of our 27 patients with generalized MG without anti-AChR antibodies. All these patients were female. The age at the onset ranged from 22 to 38 years. All patients had ocular and bulbar symptoms, and two patients also had generalized limb weakness. Two patients had pure ocular symptoms for 7 or 8 years before the development of bulbar symptoms. All anti-MuSK positive patients were treated with immunosuppressive drugs, three received plasmapheresis and one patient required mechanical ventilation. Our results are consistent with other literature reports.
Magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) have been investigated in a single neurodegenerative disease manifesting as either amyotrophic lateral sclerosis (ALS) or ...frontotemporal dementia (FTD) alone, but have not been examined in combined disorders such as ALS with FTD (ALS-FTD). To our knowledge, this study is the first attempt to demonstrate relationship between MRI abnormalities and MR spectroscopic metabolite changes of the motor cortex, frontal white matter and corticospinal tract in a patient with the diagnosis of ALS with probable upper motor neuron signs (ALS-PUMNS) and FTD. Patient presented underwent MRI of the brain and MRS. The ratio of N-acetylaspartate (NAA) to creatine (Cr), choline to Cr, myo-inositol (ml) to Cr and glutamate-glutamine (Glx) to Cr were derived from peak area measurement. Spectra from the right motor cortex, frontal white matter and corticospinal tract were obtained. MR images were evaluated for sulcus centralis enlargement, corticospinal tract hyperintensity and frontal lobes atrophy. Spectra showed reduced NAA/Cr and Glx/Cr ratio, yet the ratio of Cho/Cr exhibited significant elevation. MR images revealed sulcus centralis enlargement, high signal intensity of corticospinal tract and atrophy of both frontal lobes. Proton spectroscopic metabolic changes in a current patient fully correlate with previously reported MRS metabolic changes in ALS alone. Surprisingly, normal ml (glial marker) values have been found in almost all measured voxels of interest except in the frontal white matter. These findings differ from the previous findings in ALS or FTD alone. In conclusion, these findings support the concept that ALS, FTD and ALS-FTD may represent different manifestations of a single pathological continuum.
We observed seven patients who developed their first signs and symptoms of motor neuron disease together with signs of protrusion/prolapse of intervertebral disc. The age of the patients was between ...55 and 67, of which one female and six male patients. All of them suffered from cervical spine pain or low back pain. The female patient and one male patient developed weakness in the small feet muscles as initial symptom and they complained of paresthesia along dermatomes L5S1 and of severe pain. The other five patients developed wasting of the hands muscles. They had a rather mild pain in the cervical spine and early morning paresthesia as well as severe causalgia along dermatomes C5C6 or C6C7. After the diagnosis of compressive radiculopathy in all patients, they underwent surgical treatment and very soon developed very severe progression of muscle wasting which included muscles of limbs, trunk and bulbar innervated muscles with signs and symptoms of lower and upper motor neuron lesion. Five patients died from 12 to 15 months after surgical treatment and two patients are still living.
A 44-year-old woman developed rheumatoid arthritis, pemphigus vulgaris and myasthenia gravis. Motor neurone disease appeared 2 years later. Hashimoto's thyroiditis was diagnosed after a severe stress ...in the autumn of 1991.
