827 Possible Causes for EMG Shows Evidence of Reinnervation, Muscle Biopsy Abnormal

  • Motor Neuron Disease

    For patients with MND affecting the LMNs, the EMG will show evidence of: (1) acute denervation, which is ongoing as motor neurons degenerate, and (2) chronic denervation and[en.wikipedia.org] The results of electromyography and muscle biopsy were compatible with ALS. However, supranuclear vertical gaze palsy and slow saccades are seen.[ncbi.nlm.nih.gov] reinnervation of the muscle, as the remaining motor neurons attempt to fill in for lost motor neurons.[en.wikipedia.org]

  • Muscular Dystrophy

    This condition is typically characterized by large and abnormally distributed mitochondria on muscle biopsy, which can distinguish this condition from the other muscle conditions[ncbi.nlm.nih.gov] Under the microscope, the muscle of a positive biopsy generally shows dead tissue and abnormally large muscle fibers.[cedars-sinai.edu] Muscle biopsies from subjects 1 and 3 were severely dystrophic with abnormal immunofluorescence and western blotting indicative of α-dystroglycan hypoglycosylation.[ncbi.nlm.nih.gov]

  • Duchenne Muscular Dystrophy

    Diagnosis of Duchenne Muscular Dystrophy A muscle biopsy (taking a sample of muscle) for dystrophin studies can be done to look for abnormal levels of dystrophin in the muscle[disabled-world.com] […] fibers) For Duchenne and Becker muscular dystrophies, muscle biopsy may show whether dystrophin, a muscle protein, is missing or abnormal, and DNA testing is used to analyze[webmd.com] A muscle biopsy (taking a sample of muscle) for dystrophin studies can be done to look for abnormal levels of dystrophin in the muscle.[genome.gov]

  • Rhabdomyosarcoma

    Rhabdomyosarcoma is a rare, highly malignant soft tissue tumor that develops from cells of the striated muscle. It occurs most frequently in the head and neck and is also found in the genitourinary tract, extremities and retroperitoneum. The two most common forms are embryonal rhabdomyosarcoma and alveolar[…][symptoma.com]

  • Amyotrophic Lateral Sclerosis

    Only about 10% of ALS patients have abnormal nerve conduction study results, but the test can also suggest other diagnoses. A muscle biopsy.[webmd.com]

  • Stiff-Person Syndrome

    Previous diagnostic testing, including magnetic resonance imaging, muscle biopsy, and electromyography, showed no specific abnormalities and blood was negative for anti-GAD[redorbit.com] Trials of several muscle relaxant medications and intravenous immunoglobulin did not provide any significant relief.[redorbit.com]

  • Becker Muscular Dystrophy

    Electromyography was abnormal in all patients. Muscle biopsy in 1 patient demonstrated normal immunostaining for dystrophin.[ncbi.nlm.nih.gov] Elevated serum CK Skeletal muscle biopsy showing decreased dystrophin quantity Panel overlap The gene on this panel is also included on our Autism Intellectual Disability[unmc.edu] Dystrophin immunohistochemical analysis showed a discontinuous patchy staining pattern in cardiac and skeletal muscles biopsied from the proband.[ncbi.nlm.nih.gov]

  • Eosinophilic Fasciitis

    Currently, eosinophilic fasciitis can be diagnosed definitively only by full-thickness epidermis-to-muscle biopsy.[ajronline.org] MRI of femur demonstrated oedema and abnormal enhancement along all of the fascial planes surrounding the pelvic and thigh muscles.[imj.ie] Because of the ability of MRI to show fascial signal abnormalities clearly, it is useful also in directing the surgeon to the optimal location for biopsy, thus reducing the[ajronline.org]

  • MELAS Syndrome

    Electron microscopy of a muscle biopsy sample revealed mitochondria with abnormally arranged cristae and abnormal electron densities.[mja.com.au] Histologically, there are ragged red fibres on muscle biopsy and accumulation of abnormal mitochondria in smooth muscle.[omicsonline.org] Demonstration of ragged-red fibers on muscle biopsy.[accessanesthesiology.mhmedical.com]
