9 Possible Causes for Myopathic Features Seen on Biopsy

  • Autosomal Recessive Centronuclear Myopathy 5

    Luciano Merlini, Paolo Bonaldo, Emanuele Marzetti Frontiers Media SA, ١٨‏/٠١‏/٢٠١٦ - 248 من الصفحات Loss of muscle mass and increased fibrosis characterize both sarcopenia of aging and muscular dystrophy. Research is increasingly showing that these two conditions also share several pathophysiological mechanisms,[…][books.google.com]

  • Myopathy

    Mild myopathic features were seen on muscle biopsy of five patients (28%).[doi.org] Needle electromyography myopathic features in nine patients (26%) and a mixed neurogenic‐myopathic pattern in most (60%).[doi.org]

  • Congenital Muscular Dystrophy

    However, muscle biopsy may be normal or may show nonspecific myopathic picture or prominent fibrosis. [4] In the early stages, a striking inflammatory infiltrate may be seen[annalsofian.org] . [3] These variable histological features on muscle biopsy may cause diagnostic errors. [5] In this paper, we present a series of patients with CMD with significant inflammatory[annalsofian.org]

  • Congenital Muscular Dystrophy Type 1A

    However, muscle biopsy may be normal or may show nonspecific myopathic picture or prominent fibrosis. [4] In the early stages, a striking inflammatory infiltrate may be seen[annalsofian.org] . [3] These variable histological features on muscle biopsy may cause diagnostic errors. [5] In this paper, we present a series of patients with CMD with significant inflammatory[annalsofian.org]

  • Hyperparathyroidism

    On muscle biopsy, typical myopathic features are absent and atrophy is seen greater in type II fibers than in type 1 fibers.[rheumatologyadvisor.com]

  • Idiopathic Camptocormia

    Biopsies revealed consistently myopathic changes and in some cases fatty degeneration. Clinical or electromyographic features favoring dystonia were absent.[ncbi.nlm.nih.gov] Early signs were seen mainly during the first year and degenerative changes after 1.5 years.[ncbi.nlm.nih.gov]

  • Inclusion Body Myopathy

    Myopathic features include variation in muscle fiber size, mildly increased endomysial connective tissue and large focal regions of 'myopathic grouping' commonly seen in hereditary[nature.com] Rimmed vacuolar inclusions were noted in 35% of muscle biopsy specimens analyzed from the 13 families.[nature.com]

  • Disorder of Carbohydrate Metabolism

    The EMG shows myopathic features with or without spontaneous activity at rest.[ncbi.nlm.nih.gov] Muscle biopsy reveals severe triglyceride storage, best seen with the oil red O stain in frozen sections. This condition is transmitted as an autosomal recessive trait.[ncbi.nlm.nih.gov]

  • Distal Myopathy with Early Respiratory Muscle Involvement

    . • EMGs – myopathic. – MFMs, myotonic or pseudomyotonic discharges are common. • Muscle biopsy – Often show nonspecific dystrophic features rimmed vacuoles. – MFM is associated[slideshare.net] […] with the accumulation of dense inclusions, as well as amorphous material best seen on Gomoris trichrome and myofibrillar disruption on electron microscopy. – MFM  Immune[slideshare.net]
