146 Possible Causes for EMG Shows Myopathy

  • Hyaline Body Myopathy

    OBJECTIVE: To identify the gene and specific mutation underlying hyaline body myopathy in the family studied. METHODS: A microsatellite-based whole genome scan was performed. Linkage analysis assumed autosomal dominant inheritance and equal allele frequencies. A candidate gene approach within the linked interval and[…][ncbi.nlm.nih.gov]

  • Chronic Alcoholism

    The ECG pattern was consistent with a diagnosis of low potassium content in serum, and the EMG pattern was consistent with a diagnosis of myopathy.[ncbi.nlm.nih.gov] The repeated muscle biopsies showed that vacuolation, hyaline degeneration and significant phagocyte infiltration were observed in the muscle on the 9th day after the onset[ncbi.nlm.nih.gov]

  • Polyneuropathy

    Many tests may help show muscles are damaged (EMG, muscle enzymes) but only biopsy and chromosomal analysis are likely to show the specific etiology. 21-10.[dartmouth.edu] Reflexes are preserved until very late in myopathy. 21-9. What additional test would point to myopathy as a cause of weakness? Answer 21-9.[dartmouth.edu]

  • Polyarthritis

    EMG revealed no evidence of a generalized myopathy. Rheumatology was consulted.[shmabstracts.com] Hand x‐rays did not show any erosions. MRI cervical spine revealed mild spondylosis with normal cord morphology.[shmabstracts.com]

  • Demyelinating Disease

    Electromyography (EMG) may show features characteristic of alcoholic myopathy or neuropathy.[the-medical-dictionary.com] In chronic alcoholic myopathy, serum creatine kinase often is normal, and muscle biopsy shows atrophy, or loss of muscle fibers.[the-medical-dictionary.com]

  • Chronic Kidney Disease

    Electromyography (EMG) and nerve conduction velocity (NCV) showed abnormal spontaneous activities (ASA), suggesting myopathy, not nerve damage.[ncbi.nlm.nih.gov]

  • Duchenne Muscular Dystrophy

    MRI, EMG and NCV were compatible with proximal muscle myopathy.[ncbi.nlm.nih.gov] Muscle biopsy on vastus lateralis showed suspicious perifascicular atrophy and infiltration of mono-macrophage lineage cells complicating the diagnosis.[ncbi.nlm.nih.gov]

  • Autoimmune Necrotizing Myopathy

    An electromyogram (EMG) showed an acute noninflammatory myopathy. Prednisone 60mg daily was started to treat immune mediated necrotizing myopathy (IMNM).[shmabstracts.com] Electromyography (EMG) shows myopathic findings.[orpha.net] With IMNM, the EMG may show an irritable myopathy pattern as with other inflammatory myopathies.[understandingmyositis.org]

  • Pulmonary Fibrosis

    , low TLC, decreased DLCO, poor lung compliance Neuromuscular Myasthenia gravis, ALS f, myopathy Physical examination, EMGs g, serology Low RV, low TLC, low NIF h, low MMV[emedicine.medscape.com] Interstitial Interstitial lung disease including IPF c, NSIP d, COP e Radiography, CT scanning, physical examination, echo often shows pulmonary hypertension Low RV, low FVC[emedicine.medscape.com]

  • Oculo-Pharyngo-Distal Myopathy

    EMG showed myotonic discharges in oculopharyngodistal myopathy.[ncbi.nlm.nih.gov] EMG usually indicates a myopathic pattern. The muscle biopsy shows nonspecific features of a myopathy.[clinicalgate.com] […] in s-IBM may show neurogenic changes (ie, enlarged MUAPs), but these changes are relatively minor compared with predominance of smaller MUAPs, suggesting myopathy; fasciculation[emedicine.staging.medscape.com]
