839 Possible Causes for EMG Shows Evidence of Reinnervation, Muscle Biopsy Abnormal, Pseudohypertrophy of Calf Muscles

  • 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] Pseudohypertrophy of the calf muscles is due to fibrous tissue and fat infiltration. Involvement of the heart consists of usually terminal cardiomyopathy.[icd9data.com] Under the microscope, the muscle of a positive biopsy generally shows dead tissue and abnormally large muscle fibers.[cedars-sinai.edu]

  • 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] Clinical examination reveals muscle pseudohypertrophy affecting the calf muscles and there may be atrophy of more proximal muscles such as the quadriceps.[orpha.net]

  • Becker Muscular Dystrophy

    Electromyography was abnormal in all patients. Muscle biopsy in 1 patient demonstrated normal immunostaining for dystrophin.[ncbi.nlm.nih.gov] , fatigue and pseudohypertrophy of calf muscles[medical-dictionary.thefreedictionary.com] 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]

  • Spinal Muscular Atrophy

    Muscle biopsies showed typical signs of neurogenic damage. Molecular genetic analysis showed mutations of the ASAH1 gene.[ncbi.nlm.nih.gov] In some situations other tests such as an EMG electromyography (EMG) or muscle biopsy may be needed because it is not possible to conduct the SMN gene tests or no abnormality[genome.gov] Possible involvement of the central acoustic and visual pathways was suggested by abnormal auditory and visual evoked potentials.[ncbi.nlm.nih.gov]

  • Adult Spinal Muscular Atrophy

    Muscle biopsy- reveals evidence of devervation with no other structural abnormalities.[en.wikibooks.org] In some situations other tests such as an EMG electromyography (EMG) or muscle biopsy may be needed because it is not possible to conduct the SMN gene tests or no abnormality[genome.gov]

  • Limb-Girdle Muscular Dystrophy

    Muscle biopsy abnormalities in two individuals very early in the course of their disease suggest that biopsy would probably be useful in detection of preclinical disease in[pediatrics.aappublications.org] Pseudohypertrophy of the calf muscles is due to fibrous tissue and fat infiltration. Involvement of the heart consists of usually terminal cardiomyopathy.[icd9data.com] Some LGMD subtypes have distinguishing features, including pattern of muscle involvement, cardiac abnormalities, extramuscular involvement, and muscle biopsy findings.[ncbi.nlm.nih.gov]

  • 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]

  • Eosinophilic Fasciitis

    MRI of femur demonstrated oedema and abnormal enhancement along all of the fascial planes surrounding the pelvic and thigh muscles.[imj.ie] […] necrosis Pseudohypertrophy of muscle R iliotibial band syndrome Right iliotibial band syndrome Rupture of lunotriquetral ligament of wrist Ulcer of left ankle with muscle[icd9data.com] Currently, eosinophilic fasciitis can be diagnosed definitively only by full-thickness epidermis-to-muscle biopsy.[ajronline.org]

  • Facioscapulohumeral Muscular Dystrophy

    If genetic testing does not confirm the diagnosis, then muscle biopsy can be done.[merckmanuals.com] Pseudohypertrophy of the calf muscles is due to fibrous tissue and fat infiltration. Involvement of the heart consists of usually terminal cardiomyopathy.[icd9data.com] pseudohypertrophy LABS: CPK is usually normal histology: not impressive; most constant finding is isolated small atrophic fibers intermixed with hypertrophic muscle fibers[gait.aidi.udel.edu]
