24 Possible Causes for Percussion Myotonia, Pseudohypertrophy of Calf Muscles

  • Muscular Dystrophy

    Myotonia (prolonged muscle contraction) occurs spontaneously or is elicited by voluntary activity or by mild stimulation, such as tapping on a muscle (percussion myotonia)[neuropathology-web.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] […] typically elicited by percussion of the thenar eminence with a tendon hammer—‘percussion myotonia’.[doi.org]

  • Sarcotubular Myopathy

    There was no actionor percussion myotonia, or muscle rippling. The tendonreflexes and sensory examination were normal.[documents.tips] Abnormality of limbs Calf muscle pseudohypertrophy Quadriceps muscle weakness Abnormality of metabolism/homeostasis CREATINE PHOSPHOKINASE INCREASED Abnormality of the musculature[familydiagnosis.com] Sarcotubular myopathy Clinical features : Imported from Human Phenotype Ontology (HPO) Abnormality of head or neck Mask-like facies Neck flexor weakness Weakness of face muscles[familydiagnosis.com]

  • Congenital Muscular Dystrophy

    Myotonia (prolonged muscle contraction) occurs spontaneously or is elicited by voluntary activity or by mild stimulation, such as tapping on a muscle (percussion myotonia)[neuropathology-web.org] We report the first known Egyptian patient with FCMD, established by clinical features of generalized weakness, pseudohypertrophy of calf muscles, progressive joint contractures[ncbi.nlm.nih.gov]

  • Oculopharyngodistal Myopathy

    myotonia: delayed relaxation following percussion of the thenar eminence Grip myotonia: delayed relaxation of firm handshake Reflexes depressed Gait: high steppage (foot[evidencereviewed.com] It weakens the sarcolemma and leads to muscle necrosis What are the clinical features of Duchenne's MD? 1. Difficulty running, waddling gait 2. Calf Pseudohypertrophy 3.[brainscape.com] The calf muscles remain very strong even late in the course of these disorders.[clinicalgate.com]

  • Autosomal Dominant Limb-Girdle Muscular Dystrophy Type 1D

  • Emery-Dreifuss Muscular Dystrophy Type 1

    Myotonia (prolonged muscle contraction) occurs spontaneously or is elicited by voluntary activity or by mild stimulation, such as tapping on a muscle (percussion myotonia)[neuropathology-web.org] Contractures of the elbow, flexors, neck flexors, and calf muscles often occur; muscle pseudohypertrophy and mental retardation do not occur. A cardiomyopathy is common.[medical-dictionary.thefreedictionary.com] Kids with MD often develop enlarged calf muscles (called calf pseudohypertrophy ) as muscle tissue is destroyed and replaced by fat. How Is Muscular Dystrophy Diagnosed?[kidshealth.org]
