As this is a small retrospective series, it was not possible to determine whether DD was related to thymectomy and its potential impact on myasthenia gravis clinical control.
Brain magnetic resonance imaging MRI disclosed pons and cerebellum FLAIR and T2 hyperintense signal and mild gadolinium enhancement compatible with demyelination Figure demsielinizantes, cerebro-spinal fluid was normal. Cyclosporine dose was raised and deflazacort introduced for symptomatic desmieliniizantes of ptosis. Patient 2 had intermittent diplopia since the age of 27 and was further diagnosed with ocular myasthenia.
She underwent thymectomy one year later and evolved asymptomatic on pyridostigmine treatment, thymus pathology disclosed lymphoid hyperplasia.

Some authors state that this association may not desmoelinizantes by chance, as the incidence of DD in patients with MG is much higher than expected in the general population 6,15and both may be part of multiple autoimmune syndromes or genetic predisposition to autoimmunity 5.
Services on Demand Journal. Disease definition Polyneuropathy associated with IgM monoclonal gammapathy MG with anti-MAG myelin-associated-glycoprotein activity is a demyelinating polyneuropathy characterized clinically by sensory ataxia, tremor, paresthesia, and impaired gait.
Patients that presented with symptoms suggesting DD were selected for description. Other search option s Alphabetical list. While we evaluated ambulatory patients, Gotkine et al surveyed patients that were admitted to the hospital, which does not reflect the whole population of patients with MG in a tertiary care center.

Prednisone was switched to azathioprine due to hypertension, but symptoms only resolved when cyclosporine was started.
Differential diagnosis includes GBS and rarely some other acquired polyneuropathies monoclonal gammopathy see this terminfections, or systemic inflammatory or immune-mediated diseases, toxic neuropathies, neuropathy due to nutritional deficiency.
Patients with MG can present other autoimmune diseases in association, commonly hypo or hyperthyroidism. Desmielinizanres report on three Brazilian patients with MG that presented distinct demyelinating diseases, two monophasic and one recurrent neuromyelitis optica, several years after the diagnosis of MG, and discuss their clinical courses.
Myasthenia gravis MG is an autoimmune disease characterized by fluctuating muscle weakness, caused by impaired neuromuscular transmission. The diagnosis of MG was based on clinical history, neurological examination, electrophysiological testing and response to acetyl cholinesterase inhibitor medication pyridostigmineassessed by a neurologist trained in neuromuscular diseases. We herein describe three Brazilian patients with MG that presented different DD and discuss their clinical courses.

This methodological difference may have left to selection bias of more severe patients, among them those with DD. Does myasthenia gravis affect the brain?
CSF analysis and histological findings can provide additional supportive data but are not mandatory. Rarely, cranial nerve dysfunction and respiratory failure may occur. During the next 2 years she presented with 1 myelitis and 2 optic neuritis relapses, treated with IV desmielinizanttes.
In addition, supportive criteria include raised CSF proteins and segmental and multifocal demyelination in nerve biopsy in clinically suspected SIDP cases in which electrophysiological proof of demyelination is absent.

Myasthenia gravis and multiple sclerosis: Subacute inflammatory demyelinating polyradiculoneuropathy Prevalence: Neuromyelitis optica in patients with myasthenia gravis who underwent thymectomy.
Two of our patients have undergone thymectomy and only one presented positive ANA patient 3 ; interestingly, this was the only one that evolved to doennas recurrent DD.
