10 Possible Causes for Myopathy, Subsarcolemmal Accumulation of Normal Mitochondria

  • MELAS Syndrome

    Initially the muscle biopsy may show only muscle fibers with subsarcolemmal accumulation of mitochondria without typical RRF, but all patients with MELAS have RRF in the course[] Abstract Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is a rare neurodegenerative disease caused by the decreased ability[] MELAS syndrome (mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes) is one of the classic mitochondrial encephalomyopathies with variable clinical[]

  • Chronic Progressive External Ophthalmoplegia

    […] and intermyofibrillar accumulation of mitochondria in muscles ( mitochondria stain red).[] Here, we report a patient with chronic progressive external ophthalmoplegia complicated with inflammatory myopathy and after treated with prednisone as myositis, he had a[] In conclusion, mitochondrial myopathy was definitely diagnosed.[]

  • Carnitine Transporter Deficiency

    […] and intermyofibrillar accumulation of mitochondria in muscles ( mitochondria stain red).[] There is lipid myopathy with microvesicular lipid accumulation found in the muscle and liver as well as elevated liver transaminases and hyperammonemia.[] Early diagnosis and treatment with high-dose oral primary carnitine supplementation is critical and lifesaving and reverses the end-stage cardiomyopathy, myopathy, and episodes[]

  • Autosomal Dominant Myoglobinuria

    In addition, COX can highlight the subsarcolemmal accumulations of mitochondria.[] Elsevier Health Sciences, ٢٣‏/٠٧‏/٢٠١٤ - 14 من الصفحات Congential myopathies, Muscular dystropies, Glycogen storage diseases of muscle, and Idiopathic and Inflammatory myopathies[] 359.5 Endocrine myopathy 359.6 Inflammatory myopathy in other diseases 359.8 Other myopathies 359.9 Myopathy, unspecified 710.3 Dermatomyositis 710.4 Polymyositis ICD-10[]

  • Genetic Recurrent Myoglobinuria

    An increased immunoreactivity in the subsarcolemmal zone owing to the accumulation of mitochondria was observed (fig 2G).[] Mitochondrial Myopathies Mitochondrial myopathies are emerging as a more frequent cause of metabolic myopathy than previously recognized.[] Episodes of rhabdomyolysis usually occur when a person with a metabolic myopathy “overdoes it” (sometimes unknowingly).[]

  • Juvenile Cystinosis

    […] and intermyofibrillar accumulation of mitochondria in muscles ( mitochondria stain red).[] Adults with cystinosis develop pulmonary dysfunction, diabetes, muscle weakness, myopathy, and vascular calcification, although good adherence to treatment lessens the likelihood[] […] storage does not occur in the donor kidney, but continued accumulation in the host tissue can result in retinal blindness, corneal erosions, diabetes mellitus, a distal myopathy[]
